Subject: [PATCH 0021/1244] Remove subordinate mode and instead use a key in
 the system key-space to track metacluster membership. Use this key to
 determine if a cluster is already part of a metacluster or can be configured
 away from required mode. Disallow configuring to or from a management cluster
 that has data.

 * ``optional`` - Tenants can be created. Each transaction can choose whether or not to use a tenant. This mode is primarily intended for migration and testing purposes, and care should be taken to avoid conflicts between tenant and non-tenant data.
 * ``required`` - Tenants can be created. Each normal transaction must use a tenant. To support special access needs, transactions will be permitted to access the raw key-space using the ``RAW_ACCESS`` transaction option.
 * ``management`` - The cluster is configured as the management cluster in a metacluster. Subordinate data clusters can be registered with this management cluster and created tenants will be assigned to them. This cluster is not allowed to store data.
-* ``subordinate`` - The cluster is configured as a data cluster in a metacluster. Like ``required`` mode, except tenants cannot be created and deleted directly on a ``subordinate`` cluster.

Date: Wed, 18 May 2022 08:18:25 -0700
Subject: [PATCH 0022/1244] Remove the internal special key-space mechanism (at
 least for now), instead relying on the local logic to implement the
 metacluster functions. Add ability to force remove a cluster. Improve
 idempotency of register operation.

Subject: [PATCH 0051/1244] Change the command to create a metacluster from
 using 'configure tenant_mode=management' to 'metacluster create <NAME>'.
 Distribute this name to all processes in a metacluster. Eliminate the tenant
 mode entirely from metacluster clusters, instead relying on a metacluster
 registration key.

 * ``disabled`` - Tenants cannot be created or used. Disabled is the default tenant mode.
 * ``optional`` - Tenants can be created. Each transaction can choose whether or not to use a tenant. This mode is primarily intended for migration and testing purposes, and care should be taken to avoid conflicts between tenant and non-tenant data.
 * ``required`` - Tenants can be created. Each normal transaction must use a tenant. To support special access needs, transactions will be permitted to access the raw key-space using the ``RAW_ACCESS`` transaction option.
-* ``management`` - The cluster is configured as the management cluster in a metacluster. Subordinate data clusters can be registered with this management cluster and created tenants will be assigned to them. This cluster is not allowed to store data.

+Trace Logging
+#############
+
+Overview
+========
+
+FoundationDB processes generate log files known as trace logs that include details about the sequence of events that a process performed and record a variety of metrics about that process. These log files are useful for observing the state of a cluster over time and for debugging issues that occur in the cluster, a client, or various tools.
+
+Each file contains a sequence of events for a single process, ordered by time. Clients that use the multi-version or multi-threaded client features will generate :ref:`multiple log files simultaneously <mvc-logging>`. Each entry in the log file will be either an XML event or a JSON object that containts several mandatory fields and zero or more arbitrary fields. For example, the following is an event generated in the XML format::
+
+<Event Severity="10" Time="1579736072.656689" Type="Net2Starting" ID="0000000000000000" Machine="1.1.1.1:4000" LogGroup="default"/>
+
+Most FoundationDB processes generate trace logs in the format described in this document. This includes server and client processes, fdbcli, and backup and DR tooling.

-Trace Logging

-Overview
-========
-
-FoundationDB processes generate log files known as trace logs that include details about the sequence of events that a process performed and record a variety of metrics about that process. These log files are useful for observing the state of a cluster over time and for debugging issues that occur in the cluster, a client, or various tools.
-
-Each file contains a sequence of events for a single process, ordered by time. Clients that use the multi-version or multi-threaded client features will generate :ref:`multiple log files simultaneously <mvc-logging>`. Each entry in the log file will be either an XML event or a JSON object that containts several mandatory fields and zero or more arbitrary fields. For example, the following is an event generated in the XML format::
-
-<Event Severity="10" Time="1579736072.656689" Type="Net2Starting" ID="0000000000000000" Machine="1.1.1.1:4000" LogGroup="default"/>
-
-Most FoundationDB processes generate trace logs in the format described in this document. This includes server and client processes, fdbcli, and backup and DR tooling.

Subject: [PATCH 0076/1244] use a VectorRef for tokens to improve memory&copy

the number of tenants in a token will be typically very small
(maybe 1-2), so hashing seems unnecessary (and potentially expensive).

Also copying the cache entry will be cheaper if VectorRef is used as the
memory will just be ref-counted

Subject: [PATCH 0077/1244] add LRU cache and unit test

the boost LRU cache copies the key into the list when
doing `lru::get`. This is problematic if the memory for
the key is owned by the value (which is the case in our
use-case).

+# Load Balancing in FoundationDB
+
+In FoundationDB, often multiple *interface*s are available for the same type of *request*s. A load balancer can be used to distribute the requests to those interfaces, while awaring the possible failures.
+
+Two load balancer are provided: `basicLoadBalance` and `loadBalance`, both defined in `LoadBalance.actor.h`. The `basicLoadBalance` is a simple 
+
+## `basicLoadBalance`
+
+`basicLoadBalance` implements a simple load balancing algorithm. It applies to
+
+* Commit proxy interface
+* GetReadVersion proxy interface
+* ConfigFollower interface
+
+The interface is assumed to be always *fresh*, i.e. the list of the servers is fixed.
+
+```mermaid
+graph LR
+    H0{Has alternatives?}
+    H1[Pick up an alternative]
+    H2[Backoff]
+    H3[Request]
+    H4([Reply])
+    H5([Error])
+    H6([Never])
+    H((Start)) --> H0
+    H0 --No--> H6
+    H0 --Yes--> H1
+    H1 --No healthy alternatives--> H2 --> H1
+    H1 --Has alternative--> H3 --Success--> H4
+    H3 --Exception--> H5
+    H3 --Broken Promise --> H2
+```
+
+### Alternative pick up algorithm
+
+In `basicLoadBalance`, a *best* alternative is picked up and used at the beginning. At this stage, this alternative is randomly picked up among all alternatives. If the best alternative does not work, it will iteratively try other interfaces, see [here](#picking-up-an-alternative-in-basic-load-balancing-algorithm).
+
+## `loadBalance`
+
+`loadBalance` provides a more sophisticated implementation of load balancing. In addition of the basic load balancing, it also provides a variety of features, such like
+
+* Support for Test Storage Server ([TSS](https://github.com/apple/foundationdb/blob/main/documentation/sphinx/source/tss.rst))
+* Distance-based candidate election
+* Able to handle timeouts and exceptions with retries
+* etc.
+
+Currently it is used for
+
+* Storage Server interface
+* BlobWorker interface
+
+
+
+```mermaid
+graph LR
+    H((Start))
+    H0{Has alternatives?}
+    H1[Choose initial candidates]
+    H4([Never])
+    H5[Pick up an alternative]
+    H6[Send request]
+    H7[Wait for available alternative]
+    H8([Response])
+    H9([All alternatives failed])
+
+    H --> H0 --No--> H4
+    H0 --Yes--> H1
+    H1 --> H5
+    H5 --Has alternative--> H6
+    H5 --No alternative-->H7
+    H6 --Success--> H8
+    H6 --Failure--> H5
+    H7 --At least one alternative--> H5
+    H7 --> H9
+```
+
+Note:
+
+* Response could be an exception, e.g. `process_behind` or `request_maybe_delivered`, and will be delivered as `Error` to the caller.
+
+### Choose initial candidates
+
+Two initial candidates will be picked up before the requests start. They will be selected as the first two alternatives for the load balancer. If both of them failed, other alternatives are used in a round-robin way.
+
+#### No `QueueModel`
+
+If no `QueueModel` is provided, the initial candidates are picked up randomly. The first candidate, or the *best* alternative, will always be one of local workers.
+
+#### With `QueueModel`
+
+`QueueModel` holds information about each candidate related to future version, latency and penalty.
+
+* If the storage server is returning a future version error, it is marked as not available until some certain time.
+* Penalty is reported by storage server in each response (see `storageserver.actor.cpp:StorageServer::getPenalty`). It is determined by the write queue length and the version lagging.
+
+If `QueueModel` exists, the candidates will be picked base on the penalty. Workers with high penalties will be avoided when picking up the first two candidates. 
+
+### Pick up an alternative
+
+As mentioned above, the alternatives are chosen in the round-robin way when the first two candidates failed.
+
+If all alternatives failed, a flag is set, so if the next request fails with `process_behind`, the caller will receive the `process_behind` error.
+
+### Send requests to workers
+
+Here it is assumed that there are at least one alternative available.
+
+```mermaid
+graph LR
+    H((start))
+    H0{Is first request}
+    H1[Send first request]
+   	H2([Response])
+   	H3[Pick up next alternative]
+   	H4[Send additional request]
+
+    H --> H3
+    H3 -->H0
+   	H0 --Yes--> H1
+   	H1 --Success--> H2
+   	H1 --Timeout--> H3
+   	H0 --No--> H4
+   	H4 --First request succeed--> H2
+   	H4 --Second request succeed--> H2
+   	H4 --Additional request failed--> H3
+```
+
+If the first request failed, it is reset and the next request will be considered as the first request. Certain types of errors can also be returned as response, e.g. `request_may_be_delivered` or `process_behind`, which may not trigger a load-balancer retry.
+
+### Wait for available alternative
+
+When there is no alternatives available, the load balancer may wait until at least one interface is up.
+
+```mermaid
+graph LR
+    H0((start))
+    H1{Is first request in-flight}
+    H2[Wait for the first request]
+    H3([Response])
+    H4([Retry])
+    H5[Wait for alternatives]
+    H6([all_alternatives_failed])
+    
+    H0 --> H1
+    H1 --Yes--> H2
+    H1 --No--> H5
+    H5 --Timeout-->H6
+    H5 --Success-->H4
+    H2 --Success-->H3
+    H2 --Failed-->H4
+```
+
+Note that "Wait for alternatives" will only timeout if the alternatives are not always fresh, i.e. this only happens when accessing storage servers.
+
+#### Requests
+
+Original requests in `loadBalancer` are wrapped by `LoadBalance.actor.h:RequestData`. It provides the following additional operations besides the original `flow` request:
+
+* TSS support if `QueueModel` is available
+* Translate some errors into `maybe_delivered`, `process_behind` or retries
+* Update the `QueueModel` information including latency, penalty, etc.
+
+## Appendix
+
+### Picking up an alternative in load balancing algorithm
+
+The following script simulates the alternative picking up algorithm. The chosen alternatives will be printed out one-by-one.
+
+```python
+#! /usr/bin/env python3
+
+import random
+import time
+
+
+class Alternatives:
+
+    def __init__(self, num_alternatives):
+        self._size = num_alternatives
+    
+    def size(self):
+        return self._size
+
+    def get_best(self):
+        return random.randint(0, self._size - 1)
+
+
+# Entry
+NUM_ALTERNATIVES = 10
+alts = Alternatives(NUM_ALTERNATIVES)
+
+best_alt = alts.get_best()
+next_alt = random.randint(0, alts.size() - 2)
+if next_alt >= best_alt:
+    next_alt += 1
+start_alt = next_alt
+start_distance = (best_alt + alts.size() - start_alt) % alts.size()
+use_alt = None
+
+print("best_alt = {}".format(best_alt))
+print("start_alt = {}".format(start_alt))
+print("start_distance = {}".format(start_distance))
+
+while True:
+    for alt_num in range(0, alts.size()):
+        use_alt = next_alt
+        if next_alt == start_alt:
+            print("  Going back to the start_alt")
+            use_alt = best_alt
+        elif (next_alt + alts.size() - start_alt) % alts.size() <= start_distance:
+            print("  Entering start_distance")
+            use_alt = (next_alt + alts.size() - 1) % alts.size()
+        
+        print("Attempting alt: {}".format(use_alt))
+
+        # Next loop
+        next_alt = (next_alt + 1) % alts.size()
+        time.sleep(.2)
+```

 Keys can be moved from a server to another for several reasons:

-(2) DD splits or merges shards in order to rebalance the disk usage of servers;
-(3) DD removes redundant teams when the team number is larger than the desired number;

+(3) DD splits or merges shards in order to rebalance the disk usage of servers;

 (2) The destination server will issue transactions to read the shard range and write the key-value pairs back. The key-value will be routed to the destination server and saved in the server’s storage engine;
 (3) DD removes the source server from the shard’s ownership by modifying the system keyspace;
 (4) DD removes the shard’s information owned by the source server from the server’s team information (i.e., *shardsAffectedByTeamFailure*).
+
+# Read-aware Data Distribution
+
+## Motivation
+Before FDB 7.2, when the data distributor wants to rebalance shard, it only considers write bandwidth when choosing source and destination team, and the moved shard is chosen randomly. There are several cases where uneven read distribution from users causes a small subset of servers to be busy with read requests. This motivates the data distributor considering read busyness to minimize the read load unevenness.
+
+## When does read rebalance happen
+The data distributor will periodically check whether the read rebalance is needed. The conditions of rebalancing are 
+* the **worst CPU usage of source team >= 0.15** , which means the source team is somewhat busy;
+* the ongoing relocation is less than the parallelism budget. `queuedRelocation[ priority ] < countLimit (default 50)`;
+* the source team is not throttled to be a data movement source team. `( now() - The last time the source team was selected ) * time volumn (default 20) > read sample interval (2 min default)`;
+* the read load difference between source team and destination team is larger than 30% of the source team load;
+
+## Metrics definition
+* READ_LOAD = ceil(READ_BYTES_PER_KSECOND / PAGE_SIZE) 
+* READ_IMBALANCE = ( MAX READ_LOAD / AVG READ_LOAD )
+* MOVE_SCORE = READ_DENSITY = READ_BYTES_PER_KSECOND / SHARD_BYTE
+
+The aim for read-aware data distributor is to minimize the IMBALANCE while not harm the disk utilization balance.
+
+## Which shard to move
+Basically, the MountainChopper will handle read-hot shards distribution with following steps:
+1. The MountainChopper chooses **the source team** with the largest READ_LOAD while it satisfies HARD_CONSTRAINT, then check whether rebalance is needed; 
+    * Hard constraint:
+        * Team is healthy
+        * The last time this team was source team is larger than (READ_SAMPLE_INTERVAL / MOVEMENT_PER_SAMPLE)
+        * The worst CPU usage of source team >= 0.15
+2. Choose the destination team for moving
+    * Hard constraint:
+        * Team is healthy
+        * The team’s available space is larger than the median free space
+    * Goals
+        * The destination team has the least LOAD in a random team set while it satisfies HARD_CONSTRAINT;
+3. Select K shards on the source team of which 
+    a. `LOAD(shard) < (LOAD(src) - LOAD(dest)) * READ_REBALANCE_MAX_SHARD_FRAC `; 
+    b. `LOAD(shard) > AVG(SourceShardLoad)`; 
+    c. with the highest top-K `MOVE_SCORE`; 
+
+    We use 3.a and 3.b to set a eligible shard bandwidth for read rebalance moving. If the upper bound is too large, it’ll just make the hot shard shift to another team but not even the read load. If the upper bound is small, we’ll just move some cold shards to other servers, which is also not helpful. The default value of READ_REBALANCE_MAX_SHARD_FRAC, of which the value is up to 0.5, is 0.2 which is decided based on skewed workload test.
+4. Issue relocation request to move a random shard in the top k set. If the maximum limit of read-balance movement is reached, give up this relocation.
+
+Note: The ValleyFiller chooses a source team from a random set with the largest LOAD, and a destination team with the least LOAD.
+
+## Performance Test and Summary
+### Metrics to measure
+1. StorageMetrics trace event report “FinishedQueries” which means the current storage server finishes how many read operations. The rate of FinishedQueries is what we measure first. The better the load balance is, the more similar the FinishedQueries rate across all storage servers.
+CPU utilization. This metric is in a positive relationship with “FinishedQueries rate”. A even “FinishedQueries” generally means even CPU utilization in the read-only scenario.
+2. Data movement size. We want to achieve load balance with the movement as little as possible;
+3. StandardDeviation(FinishedQueries). It indicates how much difference read load each storage server has.
+
+### Typical test case
+120GB data, key=32B, value=200B; Single replica; 8 SS (20%) serves 80% read; 8 SS servers 60% write; 4 servers are both read and write hot;  TPS=100000, 7 read/txn + 1 write/txn; 
+
+### Test Result Summary and Recommendation 
+* With intersected sets of read-hot and write-hot servers, read-aware DD even out the read + write load on the double-hot (be both read and write hot) server, which means the converged write load is similar to disk rebalance only algorithm.
+* Read-aware DD will balance the read workload under the read-skew scenario. Starting from an imbalance `STD(FinishedQueries per minute)=16k`,the best result it can achieve is `STD(FinishedQueries per minute) = 2k`.
+* The typical movement size under a read-skew scenario is 100M ~ 600M under default KNOB value `READ_REBALANCE_MAX_SHARD_FRAC=0.2, READ_REBALANCE_SRC_PARALLELISM = 20`. Increasing those knobs may accelerate the converge speed with the risk of data movement churn, which overwhelms the destination and over-cold the source.
+* The upper bound of `READ_REBALANCE_MAX_SHARD_FRAC` is 0.5. Any value larger than 0.5 can result in hot server switching.
+* When needing a deeper diagnosis of the read aware DD, `BgDDMountainChopper_New`, and `BgDDValleyFiller_New` trace events are where to go.

Patch addresses an issue where loop generating random buffer
for the test might run in an infinite loop if KeySpace gets
exhausted but the 'targetBuffer' bytes aren't generated.

 # Load Balancing in FoundationDB
 
-In FoundationDB, often multiple *interface*s are available for the same type of *request*s. A load balancer can be used to distribute the requests to those interfaces, while awaring the possible failures.
+## Introduction
 
-Two load balancer are provided: `basicLoadBalance` and `loadBalance`, both defined in `LoadBalance.actor.h`. The `basicLoadBalance` is a simple 
+FoundationDB is a distributed key-value database. A FoundationDB cluster is constituted by one or more processes over one or more physical machines, where each process is a *worker* and takes certain *role*s, such as coordinator, proxy, TLog, storage server, etc., in the system.
+
+The interpocess communications (IPC) between the processes are supported by the [`flow`](https://github.com/apple/foundationdb/tree/main/flow) infrastructure. In the `flow` context, each process will expose one or more *interface*(s). Each interface is able to accept given type of *request*s, and *reply* `Void`, requested data or error. The interfaces and the corresponding request/reply pairs forms the IPC protocol of FoundationDB.
+
+In many cases, the same request can be proceed by multiple processes, e.g. all commit proxies can accept commit requests, and multiple storage server processes can provide values for a given key in double/triple redundancy mode. A load balancer (LB) can be used to distribute the requests over the possible interfaces, preventing one or a few processes getting overloaded. The interface candidates are also referred as *alternative*s. The LB is also able to react when one or more interfaces are (temporarily) unavailable by retrying, or re-routing the request to other candidates. The interface candidates are also known as *alternative*s.
+
+Two LBs are provided in FoundationDB: `basicLoadBalance` and `loadBalance`, both defined in [`LoadBalance.actor.h`](https://github.com/apple/foundationdb/blob/main/fdbrpc/include/fdbrpc/LoadBalance.actor.h). The `basicLoadBalance` is a simple load balancer which each interface is equally chosen; while the `loadBalance` accepts a model object, which provides [datacenter](https://apple.github.io/foundationdb/configuration.html#configuring-regions) (DC) awaring balancing algorithms, allowing requests being sent to interfaces in the same DC.
+
+In the following sections, the two LBs will be discussed in details.

Subject: [PATCH 0153/1244] Fix parsing of knob values to reject invalid
 values.

As of version 7.1, knob parsing started using std::stol which will
partially consume its input and return success, even if that's not
what we want, e.g. std::stol("4GiB") returns 4.

This changes returns the behavior of 7.0, which would consider the
above example invalid.

 #include "flow/actorcompiler.h" // must be last include
 
+// In the function names below, several terms are used repeatedly. The context-specific are defined here:
+//
+// Cost: Every read or write operation has an associated cost, determined by the number of bytes accessed.
+//       Global tag throttling quotas are specified in terms of the amount of this cost that can be consumed
+//       per second. In the global tag throttler, cost refers to the per second rate of cost consumption.
+//
+// TPS: Transactions per second. Quotas are not specified in terms of TPS, but the limits given to clients must
+//      be specified in terms of TPS because throttling is performed at the front end of transactions (before costs are
+//      known).
+//
+// Total: Refers to the total quota specified by clients through the global tag throttling API. The sum of the
+//        costs of all operations (cluster-wide) with a particular tag cannot exceed the tag's specified total quota,
+//        even if the cluster has no saturated processes.
+//
+// Desired TPS: Assuming that a tag is able to achieve its total quota, this is the TPS it would be able to perform.
+//
+// Reserved: Refers to the reserved quota specified by clients through the global tag throttling API. As long as the
+//           sum of the costs of all operations (cluster-wide) with a particular tag are not above the tag's
+//           specified reserved quota, the tag should not experience any throttling from the global tag throttler.
+//
+// Current [Cost|TPS]: Measuring the current throughput on the cluster, independent of any specified quotas.
+//
+// ThrottlingRatio: Based on the health of each storage server, a throttling ratio is provided,
+//                  informing the global tag throttler what ratio of the current throughput can be maintained.
+//
+// Limiting [Cost|TPS]: Based on the health of storage servers, a limiting throughput may be enforced.
+//
+// Target [Cost|TPS]: Based on reserved, limiting, and desired throughputs, this is the target throughput
+//                    that the global tag throttler aims to achieve (across all clients).
+//
+// PerClient TPS: Because the target throughput must be shared across multiple clients, and all clients must
+//           be given the same limits, a per-client limit is calculated based on the current and target throughputs.

+## Global Tag Throttling
+
+When the `GLOBAL_TAG_THROTTLING` knob is enabled, the ratekeeper will use the [transaction tagging feature](https://apple.github.io/foundationdb/transaction-tagging.html) to throttle tags according to the global tag throttling algorithm. This page describes the implementation of this algorithm.
+
+### Tag Quotas
+The global tag throttler bases throttling decisions on "quotas" provided by clients through the tag quota API. Each tag quota has four different components:
+
+* Reserved read quota
+* Reserved write quota
+* Total read quota
+* Total write quota
+
+The global tag throttler can not throttle tags to a throughput below the reserved quotas, and it cannot allow throughput to exceed the total quotas.
+
+### Cost
+The units for these quotas are computed as follows. The "cost" of a read operation is computed as:
+
+```
+readCost = bytesRead / SERVER_KNOBS->READ_COST_BYTE_FACTOR + 1;
+```
+
+The "cost" of a write operation is computed as:
+
+```
+writeCost = bytesWritten / CLIENT_KNOBS->WRITE_COST_BYTE_FACTOR + 1;
+```
+
+Here `bytesWritten` includes cleared bytes. The size of range clears is estimated at commit time.
+
+### Tuple Layer
+Tag quotas are stored inside of the system keyspace (with prefix `\xff/tagQuota/`). They are stored using the tuple layer, in a tuple of form: `(reservedReadQuota, totalReadQuota, reservedWriteQuota, totalWriteQuota)`. There is currently no custom code in the bindings for manipulating these system keys. However, in any language for which bindings are available, it is possible to use the tuple layer to manipulate tag quotas.
+
+### fdbcli
+The easiest way for an external client to interact with tag quotas is through `fdbcli`. To get the quota of a particular tag, run the following command:
+
+```
+fdbcli> get <tag> [reserved|total] [read|write]
+```
+
+To set the quota through `fdbcli`, run:
+
+```
+fdbcli> set <tag> [reserved|total] [read|write] <value>
+```
+
+### Limit Calculation
+The transaction budget that ratekeeper calculates and distributes to clients (via GRV proxies) for each tag is calculated based on several intermediate rate calculations, outlined in this section.
+
+* Reserved Rate: Based on reserved quota and the average transaction cost, a reserved TPS rate is computed for each tag.
+
+* Desired Rate: Based on total quota and the average transaction cost, a desired TPS rate is computed for each tag.
+
+* Limiting Rate: When a storage server is near saturation, tags contributing notably to the workload on this storage server will receive a limiting TPS rate, computed to relieve the workload on the storage server.
+
+* Target Rate: The target rate is the cluster-wide rate enforced by the global tag throttler. This rate is computed as:
+
+```
+targetTps = max(reservedTps, min(desiredTps, limitingTps));
+```
+
+* Per-Client Rate: While the target rate represents the cluster-wide desired throughput according to the global tag throttler, this budget must be shared across potentially many clients. Therefore, based on observed throughput from various clients, each client will receive an equal budget based on a per-client, per-tag rate computed by the global tag throttler. This rate is in the end what will be sent to clients to enforce throttling.
+
+## Implementation
+
+### Stat collection
+The transaction rates and costs of all transactions must be visible to the global tag throttler. Whenever a client tags a transaction, sampling is performed to determine whether to attach the tag to messages sent to storage servers and commit proxies.
+
+For read operations that are sampled (with probability `CLIENT_KNOBS->READ_TAG_SAMPLE_RATE`), read costs are aggregated on storage servers using the `TransactionTagCounter` class. This class tracks the busyness of the top-k tags affecting the storage server with read load (here `k` is determined by `SERVER_KNOBS->SS_THROTTLE_TAGS_TRACKED`). Storage servers periodically send per-tag read cost statistics to the ratekeeper through `StorageQueuingMetricsReply` messages.
+
+For write operations that are sampled (with probability `COMMIT_SAMPLE_COST`), write costs are aggregated on commit proxies in the `ProxyCommitData::ssTrTagCommitCost` object. Per-storage, per-tag write cost statistics are periodically sent from commit proxies to the ratekeeper through `ReportCommitCostEstimationRequest` messages.
+
+The ratekeeper tracks per-storage, per-tag cost statistics in the `GlobalTagThrottlerImpl::throughput` object.
+
+The ratekeeper must also track the rate of transactions performed with each tag. Each GRV proxy agreggates a per-tag counter of transactions started (without sampling). These are sent to the ratekeeper through `GetRateInfoRequest` messages. The global tag throttler then tracks per tag transaction rates in the `GlobalTagThrottlerImpl::tagStatistics` object.
+
+### Average Cost Calculation
+Quotas are expressed in terms of cost, but because throttling is enforced at the beginning of transactions, budgets need to be calculated in terms of transactions per second. To make this conversion, it is necessary to track the average cost of transactions (per-tag, and per-tag on a particular storage server).
+
+Both cost and transaction counters are smoothed using the `Smoother` class to provide stability over time. The "smoothing interval" can be modified through `SERVER_KNOBS->GLOBAL_TAG_THROTTLING_FOLDING_TIME`.
+
+### Reserved Rate Calculation
+The global tag throttler periodically reads reserved quotas from the system keyspace. Using these reserved quotas and the average cost of transactions with the given tag, a reserved TPS rate is computed. Read and write rates are aggregated as follows:
+
+```
+reservedTps = max(reservedReadTps, reservedWriteTps);
+```
+
+### Desired Rate Calculation
+Similar to reserved rate calculation, the total quota is read from the system key space. Then, using the average cost of transactions with the given tag, a desired TPS rate is computed. Read and write rates are aggregated as follows:
+
+```
+desiredTps = min(desiredReadTps, desiredWriteTps);
+```
+
+### Limiting Rate Calculation
+In addition to tag busyness statistics, the `StorageQueuingMetricsReply` messages sent from storage servers to the ratekeeper also contain metrics on the health of storage servers. The ratekeeper uses these metrics as part of its calculation of a global transaction rate (independent of tag throttling).
+
+The global tag throttler also makes use of these metrics to compute a "throttling ratio" for each storage server. This throttling ratio is computed in `StorageQueueInfo::getThrottlingRatio`. The global tag throttler uses the throttling ratio for each tracked storage server to compute a "limiting transaction rate" for each combination of storage server and tag.
+
+In the "healthy" case where no metrics are near saturation, the throttling ratio will be an empty `Optional<double>`, indicating that the storage server is not near saturation. If, on the other hand, the metrics indicate approaching saturation, the throttling ratio will be a number between 0 and 2 indicating the ratio of current throughput the storage server can serve. In this case, the global tag throttler looks at the current cost being served by the storage server, multiplies it by the throttling ratio, and computes a limiting cost for the storage server. Among all tags using significant resources on this storage server, this limiting cost is divided up according to the relative total quotas allocated to these tags. Next, a transaction limit is determined for each tag, based on how much the average transaction for the given tag affects the given storage server.
+
+These per-tag, per-storage limiting transaction rates are aggregated to compute per-tag limiting transaction rates:
+
+```
+limitingTps(tag) = min{limitingTps(tag, storage) : all storage servers}
+```
+
+If the throttling ratio is empty for all storage servers affected by a tag, then the per-tag, per-storage limiting TPS rate is also empty. In this case the target rate for this tag is simply the desired rate.
+
+If an individual zone is unhealthy, it may cause the throttling ratio for storage servers in that zone to shoot up. This should not be misinterpretted as a workload issue that requires active throttling. Therefore, the zone with the worst throttling ratios is ignored when computing the limiting transaction rate for a tag (similar to the calculation of the global transaction limit in `Ratekeeper::updateRate`).
+
+### Client Rate Calculation
+The smoothed per-client rate for each tag is tracked within `GlobalTagThrottlerImpl::PerTagStatistics`. Once a target rate has been computed, this is passed to `GlobalTagThrotterImpl::PerTagStatistics::updateAndGetPerClientRate` which adjusts the per-client rate. The per-client rate is meant to limit the busiest clients, so that at equilibrium, the per-client rate will remain constant and the sum of throughput from all clients will match the target rate.
+
+## Testing
+The `GlobalTagThrottling.toml` test provides a simple end-to-end test using the global tag throttler. Quotas are set using the internal tag quota API in the `GlobalTagThrottling` workload. This is run in parallel with the `ReadWrite` workload, which tags transactions. The number of `transaction_tag_throttled` errors is reported, along with the throughput, which should be roughly predictable based on the quota parameters chosen. 
+
+In addition to this end-to-end test, there is a suite of unit tests with the `/GlobalTagThrottler/` prefix. These tests run in a mock environment, with mock storage servers providing simulated storage queue statistics and tag busyness reports. Mock clients simulate workload on these mock storage servers, and get throttling feedback directly from a global tag throttler which is monitoring the mock storage servers.
+
+In each test, the `GlobalTagThrottlerTesting::monitor` function is used to periodically check whether or not a desired equilibrium state has been reached. If the desired state is reached and maintained for a sufficient period of time, the test passes. If the unit test is unable to reach this desired equilibrium state before a timeout, the test will fail. Commonly, the desired state is for the global tag throttler to report a client rate sufficiently close to the desired rate specified as an input to the `GlobalTagThrottlerTesting::rateIsNear` function.
+
+## Visibility
+
+### Tracing
+On the ratekeeper, every `SERVER_KNOBS->TAG_THROTTLE_PUSH_INTERVAL` seconds, the ratekeeper will call `GlobalTagThrottler::getClientRates`. At the end of the rate calculation for each tag, a trace event of type `GlobalTagThrottler_GotClientRate` is produced. This trace event reports the relevant inputs that went in to the rate calculation, and can be used for debugging.
+
+On storage servers, every `SERVER_KNOBS->TAG_MEASUREMENT_INTERVAL` seconds, there are `BusyReadTag` events for every tag that has sufficient read cost to be reported to the ratekeeper. Both cost and fractional busyness are reported.
+
+### Status
+For each storage server, the busiest read tag is reported in the full status output, along with its cost and fractional busyness.

Subject: [PATCH 0188/1244] Ensure change coordinators request came from same
 generation proxy

There was a rare but possible issue where a change coordinators request
could be in flight, but reading `\xff/coordinators` would return the old
set of coordinators, even though a previous attempt to write it returned
`commit_unknown_result`. This happened if there was an unrelated
recovery between setting `\xff/coordinators` and the updated
coordinators reaching each machine. The `commit_unknown_result` caused
by this recovery meant the change coordinators retry loop would read
`\xff/coordinators`, but since the request was ongoing it would read the
old set of coordinators. The fix is to have the cluster controller
ignore any change coordinators request from an old generation, meaning
when the retry loop reads the old coordiantors from `\xff/coordinators`,
it is guaranteed that the in progress change coordinators message will
be rejected when arriving at the cluster controller.

Subject: [PATCH 0190/1244] Fix ScopeEventFieldTypeMismatch error for
 TLogMetrics

Backport changes made to TLogServer in #4616 back to old TLog implementations.
Old implementations were using SpecialCounter, which is string. The new type
is int64_t. Without the change, we can have many events like:

<Event Severity="30" Time="1658165532.958152" DateTime="2022-07-18T17:32:12Z" Type="ScopeEventFieldTypeMismatch" ID="0000000000000000" EventType="TraceEvent.TLogMetrics" FieldName="QueueDiskBytesUsed" OldType="Int64" NewType="String" ThreadID="2451559325190099131" Machine="10.242.248.26:4703" LogGroup="xxxx" Roles="TL" />

Subject: [PATCH 0228/1244] Build fixes/improvements for sanitizers (#7657)

* Don't build fdb c shim with ubsan

This avoids duplicate symbols when linking. It doesn't really make sense
to assemble files with -fsanitize=undefined anyway, since it won't
insert instrumentation.

* Consolidate boost_asan with boost_target

Subject: [PATCH 0231/1244] Validate subrange reads in simulation (#7597)

* Add extra validation to special key space reads in simulation

* Fix bugs turned up by validating subrange reads

* Change to validateSpecialSubrangeRead

It is in general not safe to expect that a read from the special key
space returns the same results if performed again, since the
transaction may be being modified concurrently.

* Add comment

Subject: [PATCH 0242/1244] Proxy GlobalConfig reads through GRV proxies

Clients should avoid reading system keys unless authorized. Under global
config, each client reads from the system keyspace to check for new
global config keys. This commit moves these reads to a server role (the
GRV proxies) and sends the results back to GlobalConfig for an in-memory
update.

Subject: [PATCH 0248/1244] Reduce global configuration system key reads from
 proxy

Clients now poll the proxy for the latest global config for a specific
version. The proxy now periodically requests the latest global
configuration data and stores it in memory, enabling it to respond
immediately to clients with the appropriate version.

Subject: [PATCH 0273/1244] Fix incorrect range in randomSkewedUInt32()

Currently it invokes pow(10, uniform_rand(log_e(range_begin), log_e(range_end))),
which may overflow beyond UINT32_MAX.
Fix it by preventing log_e(0) case and change pow base to M_E

Subject: [PATCH 0279/1244] Move DD queue code over to using movement-reasons
 rather than priority (#7614)

* Use enum variables to invoke Priority checking

* add an explicit isDataMovementForReadBalancing function

* Set up RelocateShard in terms of data movement reason instead of priority

* Remove isMountainChopperPriority

* Remove isDiskRebalancePriority

* Fix formatting

* Fix misnamed DataMovementReason::TEAM_HEALTHY

Subject: [PATCH 0282/1244] Make dummy transaction commits tenant-aware

Dummy transaction commits are made when earlier transaction returned
commit_unknown_result or request_maybe_delivered, to affirm the status
of earlier transaction. Without tenant-awareness, these transactions
will fail due to lack of authorization in case of untrusted clients.

Subject: [PATCH 0285/1244] ddsketch_utility: Add utility scripts for ddsketch
 (#7602)

* Adds ddsketch_calc.py which implements a class for DDSketch related calculations
* Adds ddsketch_conversion.py for quickly computing a bucket index to a value or vice-versa
* Adds ddsketch_compare.py to compute how similar two ddsketch distributions are
* Adds export_graph.py to graph the ddsketch distribution outputted from mako

The arguments for ddsketch_conversion.py are:
-b, --bucket: the bucket index that we need to calculate the value from (optional)
-v, --value: the value that we need to calculate the bucket index from (optional)
-e, --error_guarantee: the error guarantee for ddsketch (optional, default is 0.005)

The arguments for ddsketch_compare.py are:
--file1: Path to first ddsketch json
--file2: Path to second ddsketch json
--txn1: The transaction type for the first file
--txn2: The transaction type for the second file
--op: The operation name (ex: GRV, GET ...)

The arguments for export_graph.py:
--file: path to ddsketch distribution
--txn, -t: Transaction type from file
--title: title for graph (optional, otherwise "Title" is used)
--savefig: Path to save the image plot (optional)
--op: Which operation to plot

Subject: [PATCH 0361/1244] Disable ShardedRocksDB in simulation when
 shard_encode_location_metadata is disabled (#7726)

* Disabled tests for ShardedRocks.

Cleaned up ShardedRocks TraceEvent.

Added assertion in ShardManager::validate().

* Added test trace.

* Make sure TraceEvent contains `ShardedRocks`.

* Exclude ShardedRocksDB when SHARD_ENCODE_LOCATION_METADATA is disabled.

Subject: [PATCH 0368/1244] C shim library: API for setting client library
 path; additional tests (#7702)

* Adding sources of the Implib.so project

* Run C unit tests and API tests with the shim library

* Reuse compilation of C test binaries with and without shim library

* Resolve client library path from an environment variable

* Refactoring: Reusable module for downloading FDB binaries

* Testing client shim library with current version and last release version

* Tests for specifying client library over an environment variable

* Enable C shim library tests on ARM

* Restore the original path for including fdb_api.hpp

* Improve cmake dependencies on doctest

* Remove unnecessary Implib.so files

* Shim library: API to specify path to the library, additional tests

* Adding shim library to Linux distribution packages

* Update link dependencies of fdb_c_shim_lib_tester

* Add dependencies on Implib.so sources

* Abort on fatal errors of shim library

* fix typo

The fdb c shim build requires python3. Let's not allow python2 to get
used there.

Otherwise we can see something like this:

Subject: [PATCH 0411/1244] Encrypt  BlobGranule delta files (#7735)

* Encrypt  BlobGranule delta files

Description

 diff-1: Address review comments

Major changes proposed by the patch are:
1. Refactor code to allow caching of 'encryption key ctx' as part of
BlobFilePointerRef. The refactoring allows snapshot and/or delta files
to store their own file encryption context.
2. Enable BlobGranule delta file encryption/decryption semantics.

Testing

BlobGranuleCorrrectness
BlobGranuleCorrectnessClean
BlobGranuleFileUnitTestToml

Description

Subject: [PATCH 0414/1244] Let the storage server reports busiest write tag

Issue #7258

The ratekeeper is recording the busiest write tag for *all* storage
servers, which throttles the traceevent. Distribute the busiest write
tag to corresponding storage servers should reduces this throttling
issue.

+//
+//   1. An ACTOR A0 allocates an object O
+//   2. A0 spawns another ACTOR A1, which depends on O
+//   3. A0 triggers A1 and then terminates, destroying O
+//   4. Since A1 is triggered by A0 while not knowing A0 is terminated and O is released, it would cause a SEGV error.
+//
+// In this header file, two classes
+//
+//   * ResourceOwningRef
+//   * ResourceWeakRef
+//
+// are provided. The ResourceOwningRef is the reference that "holds" the resource, When it is destructed, the resource
+// is also released; while ResourceWeakRef is the reference that "weakly holds" the resource. Before each access, it is
+// the user's responsibility to verify if the resource is still available, via the available() method.
+//
+// With the two classes, the issue above can be solved by:
+//
+//    1. A0 allocates the object O via ResourceOwningRef
+//    2. A0 forwards O to A1, via ResourceWeakRef
+//    3. Every time A1 accesses O, it will verify if the resource is still available.
+//    4. When A0 terminates, O is released and all ResourceWeakRef available() call will report the resource is not
+//       available anymore, preventing the SEGV error being raised.

Subject: [PATCH 0435/1244] Add test coverage for
 SpecialKeyRangeAsyncImpl::getRange  (#7671)

* Add getRange test coverage for SpecialKeyRangeAsyncImpl

* Fix the bug in SpecialKeyRangeAsyncImpl found by the test

* Refactor ConflictingKeysImpl::getRange to use containedRanges to simplify the code

* Fix file format

* Initialize SpecialKeyRangeAsyncImpl cache with correct end key

* Add release notes

* Revert "Refactor ConflictingKeysImpl::getRange to use containedRanges to simplify the code"

This reverts commit fdd298f469bf73b107e5ca29072c49774820d3d6.

 * In ``fdbcli``, integer options are now expressed as integers rather than byte strings (e.g. ``option on TIMEOUT 1000``). `(PR #7571) <https://github.com/apple/foundationdb/pull/7571>`_
+* Fixed the bug in ``ConflictingKeysImpl::getRange`` which happens when an underlying conflicting range contains the read range. Added additional test coverage for validating random ``getRange`` results from special keys. `(PR #7597) <https://github.com/apple/foundationdb/pull/7597>`_
+* Fixed the bug in ``SpecialKeyRangeAsyncImpl::getRange`` that the local cache is updated incorrectly after a cross-module read range if it touched more than one ``SpecialKeyRangeAsyncImpl`` in resolving key selectors. Extended the ``SpecialKeySpaceCorrectness`` workload to catch the bug. `(PR #7671) <https://github.com/apple/foundationdb/pull/7671>`_

Subject: [PATCH 0440/1244] blob: allow for alignment of granules to tuple
 boundaries (#7746)

* blob: read TenantMap during recovery

Future functionality in the blob subsystem will rely on the tenant data
being loaded. This fixes this issue by loading the tenant data before
completing recovery such that continued actions on existing blob
granules will have access to the tenant data.

Example scenario with failover, splits are restarted before loading the
tenant data:
BM - BlobManager
epoch 3:                        epoch 4:
  BM record intent to split.
  Epoch fails.
                                BM recovery begins.
  BM fails to persist split.
                                BM recovery finishes.
                                BM.checkBlobWorkerList()
                                  maybeSplitRange().
                                BM.monitorClientRanges().
                                  loads tenant data.

* blob: add tuple key truncation for blob granule alignment

FDB has a backup system available using the blob manager and blob
granule subsystem. If we want to audit the data in the blobs, it's a lot
easier if we can align them to something meaningful.

When a blob granule is being split, we ask the storage metrics system
for split points as it holds approximate data distribution metrics.
These keys are then processed to determine if they are a tuple and
should be truncated according to the new knob,
BG_KEY_TUPLE_TRUNCATE_OFFSET.

Here we keep all aligned keys together in the same granule even if it is
larger than the allowed granule size. The following commit will address
this by adding merge boundaries.

* blob: minor clean ups in merging code

1. Rename mergeNow -> seen. This is more inline with clocksweep naming
   and removes the confusion between mergeNow and canMergeNow.
2. Make clearMergeCandidate() reset to MergeCandidateCannotMerge to make
   a clear distinction what we're accomplishing.
3. Rename canMergeNow() -> mergeEligble().

* blob: add explicit (hard) boundaries

Blob ranges can be specified either through explicit ranges or at the
tenant level. Right now this is managed implicitly. This commit aims to
make it a little more explicit.

Blobification begins in monitorClientRanges() which parses either the
explicit blob ranges or the tenant map. As we do this and add new
ranges, let's explicitly track what is a hard boundary and what isn't.

When blob merging occurs, we respect this boundary. When a hard boundary
is encountered, we submit the found eligible ranges and start looking
for a new range beginning with this hard boundary.

* blob: create BlobGranuleSplitPoints struct

This is a setup for the following commit. Our goal here is to provide a
structure for split points to be passed around. The need is for us to be
able to carry uncommitted state until it is committed and we can apply
these mutations to the in-memory data structures.

* blob: implement soft boundaries

An earlier commit establishes the need to create data boundaries within
a tenant. The reality is we may encounter a set of keys that degnerate
to the same key prefix. We'll need to be able to split those across
granules, but we want to ensure we merge the split granules together
before merging with other granules.

This adds to the BlobGranuleSplitPoints state of new
BlobGranuleMergeBoundary items. BlobGranuleMergeBoundary contains state
saying if it is a left or right boundary. This information is used to,
like hard boundaries, force merging of like granules first.

We read the BlobGranuleMergeBoundary map into memory at recovery.

Subject: [PATCH 0465/1244] Improve test harness logging when there are no
 trace files (#7785)

* Log OldBinary even if there are no trace files

DeterminismCheck and OldBinary attributes don't actually depend on
information in the ProgramStart event, so we can add them
unconditionally.

* Add JoshuaSeed attribute to Test element in test harness

* Add NoTraceFilesFound event in test harness

There's already something similar: NoTraceFileGenerated. It appears that
the original author only wants to log that if the process exited 0
though. I'm not sure what the reason for that is so I think it's safer
to add a new event. This will make it more clear if say an old binary is
corrupt.

Subject: [PATCH 0490/1244] Fix: when a tenant creation permanently failed on
 the data cluster and started over, it could incorrectly fail with a tenant
 already exists error if the subsequent retry successfully committed during a
 commit_unknown_result error. Also expand the tenant management concurrency
 workload to include configure operations.

Subject: [PATCH 0509/1244] Better granule conversion (#7787)

* better check for granule-ification

* Handling blob granule initial split too large

* Re-evaluating split size if too large, even if read doesn't get transaction_too_old

* reworked to have blob worker propose split key

* New GranuleStatusReply to avoid seqno issue stream side effects

* Handling retries on reevaluateInitialSplit properly

* Waiting for stream to be initialized

* Checking reevaluate split for additional split points beyond proposed

* Fixing more races in reevaluate initial split

* properly handling cleaning up old change feed after split re-evaluate

* fixing granule conversion bug with hard boundaries

* fixing clear and merge check race with cycle test

* refactor missed knob check for clearAndMerge

* Fixing formatting

* review comments and improving large range conversion

* fixing typo

* more formatting

Subject: [PATCH 0520/1244] Testing upgrades to a future version of FDB (#7780)

* Enable configuring the next future protocol version as the current protocol version in FDB client, fdbserver, and fdbcli

* Auto format python files used in upgrade tests

* Add a test for upgrading to a future FDB version

* Emphasize that the options for using future protocol version are intended for test purposes only

* Make the global variable for current protocol version visible only locally

* Refactirng to avoid using currentProtocolVersion() in static intialization

* Update go bindings

 * The typical movement size under a read-skew scenario is 100M ~ 600M under default KNOB value `READ_REBALANCE_MAX_SHARD_FRAC=0.2, READ_REBALANCE_SRC_PARALLELISM = 20`. Increasing those knobs may accelerate the converge speed with the risk of data movement churn, which overwhelms the destination and over-cold the source.
 * The upper bound of `READ_REBALANCE_MAX_SHARD_FRAC` is 0.5. Any value larger than 0.5 can result in hot server switching.
 * When needing a deeper diagnosis of the read aware DD, `BgDDMountainChopper_New`, and `BgDDValleyFiller_New` trace events are where to go.
+
+## Data Distribution Diagnosis Q&A
+* Why Read-aware DD hasn't been triggered when there's a read imbalance? 
+  * Check `BgDDMountainChopper_New`, `BgDDValleyFiller_New` `SkipReason` field.
+* The Read-aware DD is triggered, and some data movement happened, but it doesn't help the read balance. Why? 
+  * Need to figure out which server is selected as the source and destination. The information is in `BgDDMountainChopper*`, `BgDDValleyFiller*`  `DestTeam` and `SourceTeam` field.
+  * Also, the `DDQueueServerCounter` event tells how many times a server being a source or destination (defined in 
+  ```c++
+  enum CountType : uint8_t { ProposedSource = 0, QueuedSource, LaunchedSource, LaunchedDest };
+  ```
+  ) for different relocation reason (`Other`, `RebalanceDisk`, `RebalanceRead`) in different phase within `DD_QUEUE_COUNTER_REFRESH_INTERVAL` (default 60) seconds. For example, 
+  ```xml
+  <Event Severity="10" Time="1659974950.984176" DateTime="2022-08-08T16:09:10Z" Type="DDQueueServerCounter" ID="0000000000000000" ServerId="0000000000000004" Other="0 1 3 2" RebalanceDisk="0 0 1 4" RebalanceRead="2 0 0 5" ThreadID="9733255463206053180" Machine="0.0.0.0:0" LogGroup="default" Roles="TS" />
+  ```
+  `RebalanceRead="2 0 0 5"` means server `0000000000000004` has been selected as for read balancing for twice, but it's not queued and executed yet. This server also has been a destination for read balancing for 5 times in the past 1 min.
+* How to track the lifecycle of a relocation attempt for balancing?
+  * First find the TraceId fields in `BgDDMountainChopper*`, `BgDDValleyFiller*`, which indicates a relocation is triggered.
+  * (Only when enabled) Find the `QueuedRelocation` event with the same `BeginPair` and `EndPair` as the original `TraceId`. This means the relocation request is queued.
+  * Find the `RelocateShard` event whose `BeginPair`, `EndPair` field is the same as `TraceId`. This event means the relocation is ongoing.

+# Set up the Azure Backup Testing Environment
+
+Make sure we built FDB with `-DBUILD_AZURE_BACKUP=ON`
+
+# Test
+
+If you run _BackupToBlob_ and _RestoreFromBlob_ workloads with the paramter _backupURL_ starts with `azure://`,
+the workload will backup to and restore from the azure blob storage.
+For example, _BackupAzureBlobCorrectness.toml_
+
+## Url format
+
+The code now supports the following style urls:
+
+- `azure://<account_name>.blob.core.windows.net/<container_name>` (The formal url format for the blob service provided by the azure storage account)
+- `azure://<ip|hostname>:<port>/<account_name>/<container_name>` (Directly providing the endpoint address for the blob service, usually for local testing)
+
+## Local test environment 
+
+We need to use the _Azurite_ to simulate an Azure blob service locally.
+Please follow the [turtorial](https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azurite?tabs=docker-hub) to start your service locally.
+
+For example,
+```
+docker run -p 10000:10000 -v `pwd`:<path> -w <path> mcr.microsoft.com/azure-storage/azurite azurite-blob --blobHost 0.0.0.0 --blobPort 10000 --oauth basic --cert ./<...>.pem --key ./<...>.key.pem --debug ./<log_file_path>
+```
+
+### Notice
+
+- To use uses _https_, we need to provide the certificates via `--cert` and `--key`
+    The detailed [turtorial](https://github.com/Azure/Azurite/blob/main/README.md#https-setup) to setup HTTPS.  (We tested with the `mkcert` method)
+- To use Azure SDKs, we need to pass `--oauth basic` option
+- Please take a look at the [difference](https://github.com/Azure/Azurite/blob/main/README.md#differences-between-azurite-and-azure-storage) between Azurite and Azure Storage

 * How to track the lifecycle of a relocation attempt for balancing?
   * First find the TraceId fields in `BgDDMountainChopper*`, `BgDDValleyFiller*`, which indicates a relocation is triggered.
   * (Only when enabled) Find the `QueuedRelocation` event with the same `BeginPair` and `EndPair` as the original `TraceId`. This means the relocation request is queued.

Subject: [PATCH 0611/1244] Granule force purging (#7846)

* Granule purge cannot delete history entry for fully deleting granule until all children are completely done splitting

* Several purging fixes related to granule history

* Fixed typo in refactor

* fixing memory model for purgeRange

* formatting

* weakening granule purge test for now

* cleanup

* First version of force purging granules

* fixing issue in BW range assignment reporting

* Fixing incorrect assert with force purging

* Error handling when checking force purged state

* fixed force purging and recover/reassign range races and check

* Handling force purge + boundary change race

* more places to check for force purged status

* fixed manager restart in the middle of force purge bug

* fixing same-BM purge and assignment races in all cases

* weakening orphaned granule history check a bit because of difficult to solve races

* fixing txn options on retry

* loading force purged ranges at start to avoid resuming a merge that is being force purged

* cleanup

* Enabling purging in granule tests, and adding check for leaked change feeds in force purge

* formatting

* missed parameter in merge conflicts

* Fixing leaked change feed race with merge and force purge

* adding change feed cleanup when new blob manager recovers in-progress merge that raced with force purge

* added forcepurge fdbcli command

Subject: [PATCH 0613/1244] Split proxy_memory_limit_exceeded to commit/grv
 specific exceptions

Currently GRV is reporting proxy_memory_limit_exceeded error which has
error message claiming Commit proxy failing. This split should remove
such confusion.

Subject: [PATCH 0631/1244] Added throttling when a blob worker falls behind
 (#7751)

* throttle the cluster when blob workers fall behind

* do not throttle on blob workers if they are not enabled

* remove an unnecessary actor

* fixed a compile error

* fetch blob worker metrics at the same interval as the rate is updated, avoid fetching the complete blob worker list too frequently

* fixed another compilation bug

* added a 5 second delay before bw throttling to prevent false positives caused by the 100e6 version jump during recovery. Lower the throttling thresholds to react much quicker to bw lag.

* fixed a number of problems

* changed the minBlobVersionRequest to look at storage server versions since this will be a lot more efficient

* fix: do not let desired go backwards

* fix: track the version of notAtLatest changefeeds for throttling

* ratekeeper now throttled blob workers by estimating the transaction per second throughput of the blob workers

* added metrics for blob worker change feeds

* added a knob to disable bw throttling

* fixed the transaction options in blob manager

+API Tester
+##########
+
+Introduction
+============
+
+API tester is a framework for implementing end-to-end tests of FDB C API, i.e. testing the API on a real
+FDB cluster through all layers of the FDB client. Its executable is ``fdb_c_api_tester``, and the source
+code is located in ``bindings/c/test/apitester``. The structure of API Tests is similar to that of the 
+Simulation Tests. The tests are implemented as workloads using FDB API, which are all built into the 
+``fdb_c_api_tester``. A concrete test configuration is defined as a TOML file, which specifies the
+combination of workloads to be executed by the test together with their parameters. The test can be then
+executed by passing the TOML file as a parameter to ``fdb_c_api_tester``. 
+
+Since simulation tests rely on the actor model to execute the tests deterministically in single-threaded
+mode, they are not suitable for testing various multi-threaded aspects of the FDB client. End-to-end API
+tests complement the simulation tests by testing the FDB Client layers above the single-threaded Native
+Client. 
+
+- The specific testing goals of the end-to-end tests are:
+- Check functional correctness of the Multi-Version Client (MVC) and Thread-Safe Client 
+- Detecting race conditions. They can be caused by accessing the state of the Native Client from wrong
+  threads or introducing other shared state without proper synchronization
+- Detecting memory management errors. Thread-safe reference counting must be used where necessary. MVC
+  works with multiple client libraries. Memory allocated by one client library must be also deallocated
+  by the same library.
+- Maintaining interoperability with other client versions.  The client functionality is made available
+  depending on the selected API version. The API changes are correctly adapted. 
+- Client API behaves correctly in case of cluster upgrades. Database and transaction state is correctly
+  migrated to the upgraded connections. Pending operations are canceled and successfully retried on the
+  upgraded connections.
+
+Implementing a Workload
+=======================
+
+Each workload is declared as a direct or indirect subclass of ``WorkloadBase`` implementing a constructor
+with ``WorkloadConfig`` as a parameter and the method ``start()``, which defines the entry point of the
+workload. 
+
+``WorkloadBase`` provides a set of methods that serve as building blocks for implementation of a workload:
+
+.. function:: execTransaction(start, cont, failOnError = true)
+
+   creates and executes an FDB transaction. Here ``start`` is a function that takes a transaction context
+   as parameter and implements the starting point of the transaction, and ``cont`` is a function implementing
+   a continuation to be executed after finishing the transaction execution. Transactions are automatically
+   retried on retryable errors. Transactions are retried by calling the ``start`` function again. In case
+   of a fatal error, the entire workload is considered as failed unless ``failOnError`` is set to ``false``.
+
+.. function:: schedule(task)
+
+   schedules a task for asynchronous execution. It is usually used in the continuations to schedule 
+   the next step of the workload.
+
+.. function:: info(msg) 
+              error(msg) 
+              
+   are used for logging a message with a tag identifying the workload. Issuing an error message marks
+   the workload as failed.
+
+The transaction context provides methods for implementation of the transaction logics:
+
+.. function:: tx()
+   
+   the reference to the FDB transaction object
+
+.. function:: continueAfter(future, cont, retryOnError = true)
+   
+   set a continuation to be executed when the future is ready. The ``retryOnError`` flag controls whether
+   the transaction should be automatically retried in case the future results in a retriable error.
+
+.. function:: continueAfterAll(futures, cont)
+   
+   takes a vector of futures and sets a continuation to be executed when all of the futures get ready.
+   The transaction is retried if at least one of the futures results in an error. This method is useful 
+   for handling multiple concurrent reads.
+
+.. function:: commit() 
+   
+   commit and finish the transaction. If the commit is successful, the execution proceeds to the
+   continuation of ``execTransaction()``. In case of a retriable error the transaction is
+   automatically retried. A fatal error results in a failure of the workoad.
+
+
+.. function:: done() 
+   
+   finish the transaction without committing. This method should be used to finish read transactions. 
+   The transaction gets destroyed and execution proceeds to the continuation of ``execTransaction()``.
+   Each transaction must be finished either by ``commit()`` or ``done()``, because otherwise
+   the framework considers that the transaction is still being executed, so it won't destroy it and
+   won't call the continuation.
+
+.. function:: onError(err) 
+   
+   Handle an error: restart the transaction in case of a retriable error, otherwise fail the workload.
+   This method is typically used in the continuation of ``continueAfter`` called with
+   ``retryOnError=false`` as a fallback to the default error handling.
+
+A workload execution ends automatically when it is marked as failed or its last continuation does not
+schedule any new task or transaction. 
+
+The workload class should be defined in the namespace FdbApiTester. The file name convention is
+``Tester{Name}Workload.cpp`` so that we distinguish them from the source files of simulation workloads.
+
+Basic Workload Example
+======================
+
+The code below implements a workload that consists of only two transactions. The first one sets a
+randomly generated key to a randomly generated value, and the second one reads the key and checks if
+the returned value matches the written one.
+
+.. literalinclude:: ../../../bindings/c/test/apitester/TesterExampleWorkload.cpp
+   :language: C++
+   :lines: 21-
+
+The workload is implemented in the method ``setAndGet``. It generates a random key and a random value
+and executes a transaction that writes that key-value pair and commits. In the continuation of the
+first ``execTransaction`` call, we execute the second transaction that reads the same key. The read
+operation returns a future. So we call ``continueAfter`` to set a continuation for that future. In the
+continuation we check if the returned value matches the written one and finish the transaction by
+calling ``ctx->done()``. After completing the second transaction we execute the continuation passed
+as parameter to the ``setAndGet`` method by the start method. In this case it is ``NO_OP_TASK``, which
+does nothing and so finishes the workload.
+
+Finally, we declare an instance ``WorkloadFactory`` to register this workload with the name ``SetAndGet``.
+
+Note that we use ``workloadId`` as a key prefix. This is necessary for isolating the key space of this
+workload, because the framework may be instructed to create multiple instances of the ``SetAndGet``
+workload. If we do not isolate the key space, another workload can write a different value for the
+same key and so break the assumption of the test.
+
+The workload is implemented using the internal C++ API, implemented in ``fdb_api.hpp``. It introduces
+a set of classes representing the FDB objects (transactions, futures, etc.). These classes provide C++-style 
+methods wrapping FDB C API calls and automate memory management by means of reference counting.
+
+Implementing Control Structures
+===============================
+
+Our basic workload executes just 2 transactions, but in practice we want to have workloads that generate
+multiple transactions. The following code demonstrates how we can modify our basic workload to generate
+multiple transactions in a loop. 
+
+.. code-block:: C++
+
+   class SetAndGetWorkload : public WorkloadBase {
+   public:
+      ...
+      int numIterations;
+      int iterationsLeft;
+
+      SetAndGetWorkload(const WorkloadConfig& config) : WorkloadBase(config) {
+         keyPrefix = fdb::toBytesRef(fmt::format("{}/", workloadId));
+         numIterations = config.getIntOption("numIterations", 1000);
+      }
+
+      void start() override {
+         iterationsLeft = numIterations;
+         setAndGetLoop();
+      }
+
+      void setAndGetLoop() {
+         if (iterationsLeft == 0) {
+            return;
+         }
+         iterationsLeft--;
+         setAndGet([this]() { setAndGetLoop(); });
+      }
+      ...
+   }
+
+We introduce a workload parameter ``numIterations`` to specify the number of iterations. If not specified
+in the test configuration it defaults to 1000.
+
+The method ``setAndGetLoop`` implements the loop that decrements iterationsLeft counter until it reaches 0
+and each iteration calls setAndGet with a continuation that returns the execution to the loop. As you
+can see we don't need any change in ``setAndGet``, just call it with another continuation. 
+
+The pattern of passing a continuation as a parameter also can be used to decompose the workload into a
+sequence of steps. For example,  we can introduce setup and cleanUp steps to our workload and modify the
+``setAndGetLoop`` to make it composable with an arbitrary continuation:
+
+.. code-block:: C++
+
+    void start() override {
+       setup([this](){
+           iterationsLeft = numIterations;
+           setAndGetLoop([this](){
+               cleanup(NO_OP_TASK);
+           });
+       });
+    }
+
+    void setAndGetLoop(TTaskFct cont) {
+       if (iterationsLeft == 0) {
+           schedule(cont);
+       }
+       iterationsLeft--;
+       setAndGet([this, cont]() { setAndGetLoop(cont); });
+   }
+
+   void setup(TTaskFct cont) { ... }
+
+   void cleanup(TTaskFct cont) {  ... }
+
+Note that we call ``schedule(cont)`` in ``setAndGetLoop`` instead of calling the continuation directly.
+In this way we avoid keeping ``setAndGetLoop`` in the call stack, when executing the next step.
+
+Subclassing ApiWorkload
+=======================
+
+``ApiWorkload`` is an abstract subclass of ``WorkloadBase`` that provides a framework for a typical
+implementation of API test workloads. It implements a workflow consisting of cleaning up the key space
+of the workload, populating it with newly generated data and then running a loop consisting of random
+database operations. The concrete subclasses of ``ApiWorkload`` are expected to override the method
+``randomOperation`` with an implementation of concrete random operations.
+
+The ``ApiWorkload`` maintains a local key-value store that mirrors the part of the database state
+relevant to the workload. A successful database write operation should be followed by a continuation
+that performs equivalent changes in the local store, and the results of a database read operation should
+be validated against the values from the local store. 
+
+Test Configuration
+==================
+
+A concrete test configuration is specified by a TOML file. The file must contain one ``[[test]]`` section
+specifying the general settings for test execution followed by one or more ``[[test.workload]]``
+configuration sessions, specifying the workloads to be executed and their parameters. The specified
+workloads are started all at once and executed concurrently.
+
+The ``[[test]]`` section can contain the following options:
+
+- ``title``: descriptive title of the test
+- ``multiThreaded``: enable multi-threading (default: false)
+- ``minFdbThreads`` and ``maxFdbThreads``: the number of FDB (network) threads to be randomly selected
+  from the given range (default: 1-1). Used only if ``multiThreaded=true``. It is also important to use
+  multiple database instances to make use of the multithreading.
+- ``minDatabases`` and ``maxDatabases``: the number of database instances to be randomly selected from
+  the given range (default 1-1). The transactions of all workloads are randomly load-balanced over the
+  pool of database instances.
+- ``minClients`` and ``maxClients``: the number of clients, i.e. instances of each workload, to be
+  randomly selected from the given range (default 1-8).
+- ``minClientThreads`` and ``maxClientThreads``: the number of client threads, i.e. the threads used
+  for execution of the workload, to be randomly selected from the given range (default 1-1).
+- ``blockOnFutures``: use blocking waits on futures instead of scheduling future callbacks asynchronously
+  (default: false)
+- ``buggify``: Enable client-side failure injection (default: false)
+- ``databasePerTransaction``: Create a separate database instance for each transaction (default: false).
+  It is a special mode useful for testing bugs related to creation and destruction of database instances. 
+- ``fdbCallbacksOnExternalThreads``: Enables the option ``FDB_NET_OPTION_CALLBACKS_ON_EXTERNAL_THREADS``
+  causting the callbacks of futures to be executed directly on the threads of the external FDB clients 
+  rather than on the thread of the local FDB client. 
+
+The workload section ``[[test.workload]]`` must contain the attribute name matching the registered name
+of the workload to be executed. Other options are workload-specific. 
+
+The subclasses of the ``ApiWorkload`` inherit the following configuration options:
+
+- ``minKeyLength`` and ``maxKeyLength``: the size range of randomly generated keys (default: 1-64)
+- ``minValueLength`` and ``maxValueLength``:  the size range of randomly generated values 
+  (default: 1-1000)
+- ``maxKeysPerTransaction``: the maximum number of keys per transaction (default: 50)
+- ``initialSize``: the number of key-value pairs in the initially populated database (default: 1000)
+- ``readExistingKeysRatio``: the probability of choosing an existing key for read operations 
+  (default: 0.9)
+- ``numRandomOperations``: the number of random operations to be executed per workload (default: 1000)
+- ``runUntilStop``: run the workload indefinitely until the stop command is received (default: false).
+   This execution mode in upgrade tests and other scripted tests, where the workload needs to
+   be generated continously until completion of the scripted test.
+- ``numOperationsForProgressCheck``: the number of operations to be performed to confirm a progress 
+   check (default: 10). This option is used in combination with ``runUntilStop``. Progress checks are
+   initiated by a test script to check if the client workload is successfully progressing after a
+   cluster change.
+
+Executing the Tests
+===================
+
+The ``fdb_c_api_tester`` executable takes a single TOML file as a parameter and executes the test
+according to its specification. Before that we must create a FDB cluster and pass its cluster file as
+a parameter to ``fdb_c_api_tester``. Note that multithreaded tests also need to be provided with an
+external client library. 
+
+For example, we can create a temporary cluster and use it for execution of one of the existing API tests:
+
+.. code-block:: bash
+
+   ${srcDir}/tests/TestRunner/tmp_cluster.py --build-dir ${buildDir} -- \
+      ${buildDir}/bin/fdb_c_api_tester \
+      --cluster-file @CLUSTER_FILE@ \
+      --external-client-library=${buildDir}/bindings/c/libfdb_c_external.so \
+      --test-file ${srcDir}/bindings/c/test/apitester/tests/CApiCorrectnessMultiThr.toml
+
+The test specifications added to the ``bindings/c/test/apitester/tests/`` directory are executed as a part
+of the regression test suite. They can be executed using the ``ctest`` target ``fdb_c_api_tests``:
+
+.. code-block:: bash
+   
+   ctest -R fdb_c_api_tests -VV

Subject: [PATCH 0649/1244] Guard initPersistentState() calls with timeout.
 (#7649)

We've observed the recovery process stuck in initPersistentState,
while waiting to acquire persistentDataCommitLock. All of the
other places in that function which potentially interact with a
disk are guarded by a timeout: TLOG_MAX_CREATE_DURATION.

Since it's possible that the current holder of that lock is
stuck in persistentData->commit(), it makes sense to add
a timeout around the entire function, rather than each of the
places where it might get stuck on an I/O operation.

The end result is that after 10 seconds, this process will fail
and cluster recovery will restart.

 #. ``\xff\xff/management/tenant/map/<tenant>`` Read/write. Setting a key in this range to any value will result in a tenant being created with name ``<tenant>``. Clearing a key in this range will delete the tenant with name ``<tenant>``. Reading all or a portion of this range will return the list of tenants currently present in the cluster, excluding any changes in this transaction. Values read in this range will be JSON objects containing the metadata for the associated tenants.
 #. ``\xff\xff/management/tenant/rename/<tenant>`` Read/write. Setting a key in this range to an unused tenant name will result in the tenant with the name ``<tenant>`` to be renamed to the value provided. If the rename operation is a transaction retried in a loop, it is possible for the rename to be applied twice, in which case ``tenant_not_found`` or ``tenant_already_exists`` errors may be returned. This can be avoided by checking for the tenant's existence first.

Subject: [PATCH 0654/1244] Update BlobCipher cache to respect EKP/KMS
 cipherKey TTL (#7885)

Description

FDB native encryption data at-rest supports two type of cipher-keys
in-memory caching:
1. Revocable keys - with a definite expiry (future timestamp)
2. Non-revocable keys - with or without expiry timestamp and/or
refreshAt timestamp.

Patch update BlobCipherKey in-memory cache to respect EKP/KMS
supplied 'refreshAt' and 'expireAt' timestamp. GetLatestCipher
validates `cipher key freshness' as well as GetCipherKey checks
for 'cipher key liveness' before replying details to the caller.

Patch also optimizes the BlobCipher module logging by taking
following measures:
1. BLOB_CIPHER_DEBUG macro to guard spammy log messages needed
mostly for debugging failures.
2. Minimize log volume by logging cipherKey details for any new
key added to the cache, key-refreshes are not logged.
3. Categorize logs into: debug, info and warn on per-usecase basis

Subject: [PATCH 0705/1244] Improved purge tests (#7911)

* doing force purge at the end of the test if it didn't happen during

* better checking for granule metadata left over after purge

* retrying for in-flight granules that weren't known before purge

* letting test pass for a hard to fix purge case

* changed post-test force purge to only be after final availability check

Subject: [PATCH 0724/1244] Remove a unit test which invokes undefined behavior
 (#7937)

The intent of this test is to show that figureVersion does something
reasonable if undefined behavior is invoked, but just invoking it is
already problematic so it's not an interesting test.

Subject: [PATCH 0730/1244] Blob Granules Cleanup (#7941)

* Cleaned up BlobGranule TODO + FIXMEs and addressed some

* popping feed at correct version

* blob worker taking over a granule will pop from where previous worker left off

* addressed fixme of blob worker not re-snapshotting from old change feed

* formatting

* more change feed popped fixes after pop updates

* Getting rid of change feed parallelism lock since it can cause deadlocks in fetching, and relying on full fetch lock

* New blob worker metric and fixing old one

* server-side popped checking still doesn't work because of pops at non-mutation versions

* format

+    This is the central configuration class for test harness. The values in this class are exposed globally through
+    a global variable test_harness.config.config. This class provides some "magic" to keep test harness flexible.
+    Each parameter can further be configured using an `_args` member variable which is expected to be a dictionary.
+    * The value of any variable can be set through the command line. For a variable named `variable_name` we will
+      by default create a new command line option `--variable-name` (`_` is automatically changed to `-`). This
+      default can be changed by setting the `'long_name'` property in the `_arg` dict.
+    * In addition the user can also optionally set a short-name. This can be achieved by setting the `'short_name'`
+      property in the `_arg` dictionary.
+    * All additional properties in `_args` are passed to `argparse.add_argument`.
+    * If the default of a variable is `None` the user should explicitly set the `'type'` property to an appropriate
+      type.
+    * In addition to command line flags, all configuration options can also be controlled through environment variables.
+      By default, `variable-name` can be changed by setting the environment variable `TH_VARIABLE_NAME`. This default
+      can be changed by setting the `'env_name'` property.
+    * Test harness comes with multiple executables. Each of these should use the config facility. For this,
+      `Config.build_arguments` should be called first with the `argparse` parser. Then `Config.extract_args` needs
+      to be called with the result of `argparse.ArgumentParser.parse_args`. A sample example could look like this:
+      ```
+      parser = argparse.ArgumentParser('TestHarness', formatter_class=argparse.ArgumentDefaultsHelpFormatter)
+      config.build_arguments(parser)
+      args = parser.parse_args()
+      config.extract_args(args)
+      ```
+    * Changing the default value for all executables might not always be desirable. If it should be only changed for
+      one executable Config.change_default should be used.

Subject: [PATCH 0761/1244] RegisterWorker to cancel existing watcher if
 reusing the worker (#7949)

Description

Register worker maintain 'id_worker' map to track the worker interface
registeration, it also sets 'WorkerAvailabilityWatcher' actor to track
for failures. However, if worker is already registered but interface gets
updated, the existing code doesn't actively cancel the watcher. One possible
race condition is, old watcher detects worker failure and removes the worker
from id_worker map even before the new watcher started monitoring the new
interface. If such a scenario is hit, it trips an assert in rebootAndCheck
routine which expects the worker should be present in the id_worker map.

Patch addresses the race condition by actively cancelling existing watcher
actor before registering the new watcher actor.

Subject: [PATCH 0804/1244] KMS connector to assist encryption enabled perf
 runs (#7978)

Description

FDB Native encryption requires integration with external
KeyMangement Services to fetch required encryption keys.
For simulation runs, there exists SimKmsConnector implementation
that fakes interaction with external KMS.

Major changes suggested in the patch:
1. Enable setting KMS_CONNECTOR_TYPE via command line arguments.
2. If "FDBPerfKmsConnector" is set as KMS_CONNECTOR_TYPE, then
allow using SimKmsConnector implementation.

Note: SimKmsConnector can handle process reboots.

Testing

Subject: [PATCH 0807/1244] Implement TenantCacheEntry in-memory cache (#7801)

* Implement TenantCacheEntry in-memory cache

Description

  diff-4: TraceEvent usage improvements
  diff-3: Address review comments
  diff-2: Add APIs to read counter values, test improvements
  diff-1: Address review comments

Major changes includes:
1. Implements an actor that enables an in-memory caching of
TenantCacheEntry object, allowing the caller to embed custom
information along with TenantCacheEntry.
2. The cache follows read-through cache semantics where the entry
gets loaded from underlying database on a miss.
3. The cache implements a "periodic poller" to refresh known Tenants
by consulting the database. Once a database keyrange-watch feature is
available, cache shall be updated.

Bonus:
Implement a 'recurringAsync' addition to genericActors allowing caller
to schedule a periodic task registering an "actor functor"; the routine
'waits' for the actor unlike existing 'recurring' implementation.

Testing

Subject: [PATCH 0809/1244] flow: allow for patch version to be set again for
 protocol version

While only major and minor version matters for fdb releases regarding
protocol version, this makes testing a little bit easier.

Subject: [PATCH 0810/1244] Fix missing localities for fdbserver

The localities are stored in ServerDBInfo for calculating distances to other
processes. The localities are not set when creating ServerDBInfo, thus any
distances calculated before UpdateServerDBInfoRequest will be wrong.

This PR fixes this issue, thus preventing unnecessary cross DC calls,
especially for index prefetching on the storage servers.

+# Dynamic Knobs
+
+This document is largely adapted from original design documents by Markus
+Pilman and Trevor Clinkenbeard.
+
+## Background
+
+FoundationDB parameters control the behavior of the database, including whether
+certain features are available and the value of internal constants. Parameters
+will be referred to as knobs for the remainder of this document. Currently,
+these knobs are configured through arguments passed to `fdbserver` processes,
+often controlled by `fdbmonitor`. This has a number of problems:
+
+1. Updating knobs involves updating `foundationdb.conf` files on each host in a
+   cluster. This has a lot of overhead and typically requires external tooling
+   for large scale changes.
+2. All knob changes require a process restart.
+3. We can't easily track the history of knob changes.
+
+## Overview
+
+The dynamic knobs project creates a strictly serializable quorum-based
+configuration database stored on the coordinators. Each `fdbserver` process
+specifies a configuration path and applies knob overrides from the
+configuration database for its specified classes.
+
+### Caveats
+
+The configuration database explicitly does not support the following:
+
+1. A high load. The update rate, while not specified, should be relatively low.
+2. A large amount of data. The database is meant to be relatively small (under
+   one megabyte). Data is not sharded and every coordinator stores a complete
+   copy.
+3. Concurrent writes. At most one write can succeed at a time, and clients must
+   retry their failed writes.
+
+## Design
+
+### Configuration Path
+
+Each `fdbserver` process can now include a `--config_path` argument specifying
+its configuration path. A configuration path is a hierarchical list of
+configuration classes specifying which knob overrides the `fdbserver` process
+should apply from the configuration database. For example:
+
+```bash
+$ fdbserver --config_path classA/classB/classC ...
+```
+
+Knob overrides follow descending priority:
+
+1. Manually specified command line knobs.
+2. Individual configuration class overrides.
+  * Subdirectories override parent directories. For example, if the
+    configuration path is `az-1/storage/gp3`, the `gp3` configuration takes
+    priority over the `storage` configuration, which takes priority over the
+    `az-1` configuration.
+3. Global configuration knobs.
+4. Default knob values.
+
+#### Example
+
+For example, imagine an `fdbserver` process run as follows:
+
+```bash
+$ fdbserver --datadir /mnt/fdb/storage/4500 --logdir /var/log/foundationdb --public_address auto:4500 --config_path az-1/storage/gp3 --knob_disable_asserts false
+```
+
+And the configuration database contains:
+
+| ConfigClass | KnobName            | KnobValue |
+|-------------|---------------------|-----------|
+| az-2        | page_cache_4k       | 8e9       |
+| storage     | min_trace_severity  | 20        |
+| az-1        | compaction_interval | 280       |
+| storage     | compaction_interval | 350       |
+| az-1        | disable_asserts     | true      |
+| \<global\>  | max_metric_size     | 5000      |
+| gp3         | max_metric_size     | 1000      |
+
+The final configuration for the process will be:
+
+| KnobName            |  KnobValue  | Explanation |
+|---------------------|-------------|-------------|
+| page_cache_4k       | \<default\> | The configuration database knob override for `az-2` is ignored, so the compiled default is used |
+| min_trace_severity  | 20          | Because the `storage` configuration class is part of the process’s configuration path, the corresponding knob override is applied from the configuration database |
+| compaction_interval | 350         | The `storage` knob override takes precedence over the `az-1` knob override |
+| disable_asserts     | false       | This knob is manually overridden, so all other overrides are ignored |
+| max_metric_size     | 1000        | Knob overrides for specific configuration classes take precedence over global knob overrides, so the global override is ignored |
+
+### Clients
+
+Clients can write to the configuration database using transactions.
+Configuration database transactions are differentiated from regular
+transactions through specification of the `USE_CONFIG_DATABASE` database
+option.
+
+In configuration transactions, the client uses the tuple layer to interact with
+the configuration database. Keys are tuples of size two, where the first item
+is the configuration class being written, and the second item is the knob name.
+The value should be specified as a string. It will be converted to the
+appropriate type based on the declared type of the knob being set.
+
+Below is a sample Python script to write to the configuration database.
+
+```python
+import fdb
+
+fdb.api_version(720)
+
+@fdb.transactional
+def set_knob(tr, knob_name, knob_value, config_class, description):
+        tr['\xff\xff/description'] = description
+        tr[fdb.tuple.pack((config_class, knob_name,))] = knob_value
+
+# This function performs two knob changes transactionally.
+@fdb.transactional
+def set_multiple_knobs(tr):
+        tr['\xff\xff/description'] = 'description'
+        tr[fdb.tuple.pack((None, 'min_trace_severity',))] = '10'
+        tr[fdb.tuple.pack(('az-1', 'min_trace_severity',))] = '20'
+
+db = fdb.open()
+db.options.set_use_config_database()
+
+set_knob(db, 'min_trace_severity', '10', None, 'description')
+set_knob(db, 'min_trace_severity', '20', 'az-1', 'description')
+```
+
+### Disable the Configuration Database
+
+The configuration database includes both client and server changes and is
+enabled by default. Thus, to disable the configuration database, changes must
+be made to both.
+
+#### Server
+
+The configuration database can be disabled by specifying the ``fdbserver``
+command line option ``--no-config-db``. Note that this option must be specified
+for *every* ``fdbserver`` process.
+
+#### Client
+
+The only client change from the configuration database is as part of the change
+coordinators command. The change coordinators command is not considered
+successful until the configuration database is readable on the new
+coordinators. This will cause the change coordinators command to hang if run
+against a database with dynamic knobs disabled. To disable the client side
+configuration database liveness check, specify the ``--no-config-db`` flag when
+changing coordinators. For example:
+
+```
+fdbcli> coordinators auto --no-config-db
+```
+
+## Status
+
+The current state of the configuration database is output as part of `status
+json`. The configuration path for each process can be determined from the
+``command_line`` key associated with each process.
+
+Sample from ``status json``:
+
+```
+"configuration_database" : {
+    "commits" : [
+        {
+            "description" : "set some knobs",
+            "timestamp" : 1659570000,
+            "version" : 1

+        {
+            "description" : "make some other changes",
+            "timestamp" : 1659570000,
+            "version" : 2

+
+## Detailed Implementation
+
+The configuration database is implemented as a replicated state machine living
+on the coordinators. This allows configuration database transactions to
+continue to function in the event of a catastrophic loss of the transaction
+subsystem.
+
+To commit a transaction, clients run the two phase Paxos protocol. First, the
+client asks for a live version from a quorum of coordinators. When a
+coordinator receives a request for its live version, it increments its local
+live version by one and returns it to the client. Then, the client submits its
+writes at the live version it received in the previous step. A coordinator will
+accept the commit if it is still on the same live version. If a majority of
+coordinators accept the commit, it is considered committed.
+
+### Coordinator
+
+Each coordinator runs a ``ConfigNode`` which serves as a replica storing one
+full copy of the configuration database. Coordinators never communicate with
+other coordinators while processing configuration database transactions.
+Instead, the client runs the transaction and determines when it has quorum
+agreement.
+
+Coordinators serve the following ``ConfigTransactionInterface`` to allow
+clients to read from and write to the configuration database.
+
+#### ``ConfigTransactionInterface``
+| Request          | Request fields                                                 | Reply fields                                                                                  | Explanation                                                                                                      |

+| Get              | (configuration class, knob name, coordinatorsHash, generation) | (knob value or empty) or (coordinators_changed error) or (transaction_too_old error)          | Returns the current value stored at the specified configuration class and knob name, or empty if no value exists |
+| GetConfigClasses | (coordinatorsHash, generation)                                 | (configuration classes) or (coordinators_changed error) or (transaction_too_old error)        | Returns a list of all configuration classes stored in the configuration database                                 |
+| GetKnobs         | (configuration class, coordinatorsHash, generation)            | (knob names) or (coordinators_changed error) or (transaction_too_old error)                   | Returns a list of all knob names stored for the provided configuration class                                     |
+| Commit           | (mutation list, coordinatorsHash, generation)                  | ack or (coordinators_changed error) or (commit_unknown_result error) or (not_committed error) | Commit mutations set by the transaction                                                                          |
+
+Coordinators also serve the following ``ConfigFollowerInterface`` to provide
+access to (and modification of) their current state. Most interaction through
+this interface is done by the cluster controller through its
+``IConfigConsumer`` implementation living on the ``ConfigBroadcaster``.
+

+
+### Cluster Controller
+
+The cluster controller runs a singleton ``ConfigBroadcaster`` which is
+responsible for periodically polling the ``ConfigNode``s for updates, then
+broadcasting these updates to workers through the ``ConfigBroadcastInterface``.
+When workers join the cluster, they register themselves and their
+``ConfigBroadcastInterface`` with the broadcaster. The broadcaster then pushes
+new updates to registered workers.
+
+The ``ConfigBroadcastInterface`` is also used by ``ConfigNode``s to register
+with the ``ConfigBroadcaster``. ``ConfigNode``s need to register with the
+broadcaster because the broadcaster decides when the ``ConfigNode`` may begin
+serving requests, based on global information about status of other
+``ConfigNode``s. For example, if a system with three ``ConfigNode``s suffers a
+fault where one ``ConfigNode`` loses data, the faulty ``ConfigNode``  should
+not be allowed to begin serving requests again until it has been rolled forward
+and is up to date with the latest state of the configuration database.
+
+#### ``ConfigBroadcastInterface``
+
+| Request    | Request fields                                             | Reply fields                  | Explanation                                                                                 |
+|------------|------------------------------------------------------------|-------------------------------|---------------------------------------------------------------------------------------------|
+| Snapshot   | (snapshot, version, restartDelay)                          | ack                           | A snapshot of the configuration database sent by the broadcaster to workers                 |
+| Changes    | (changes, mostRecentVersion, restartDelay)                 | ack                           | A list of changes up to and including mostRecentVersion, sent by the broadcaster to workers |
+| Registered | ()                                                         | (registered, lastSeenVersion) | Sent by the broadcaster to new ``ConfigNode``s to determine their registration status       |
+| Ready      | (snapshot, snapshotVersion, liveVersion, coordinatorsHash) | ack                           | Sent by the broadcaster to new ``ConfigNode``s to allow them to start serving requests      |
+
+### Worker
+
+Each worker runs a ``LocalConfiguration`` instance which receives and applies
+knob updates from the ``ConfigBroadcaster``. The local configuration maintains
+a durable ``KeyValueStoreMemory`` containing the following:
+
+* The latest known configuration version
+* The most recently used configuration path
+* All knob overrides corresponding to the configuration path at the latest known version
+
+Once a worker starts, it will:
+
+* Apply manually set knobs
+* Read its local configuration file
+  * If the stored configuration path does not match the configuration path
+    specified on the command line, delete the local configuration file
+  * Otherwise, apply knob updates from the local configuration file. Manually
+    specified knobs will not be overridden
+  * Register with the broadcaster to receive new updates for its configuration
+    classes
+    * Persist these updates when received and restart if necessary
+
+### Knob Atomicity
+
+All knobs are classified as either atomic or non-atomic. Atomic knobs require a
+process restart when changed, while non-atomic knobs do not.
+
+### Compaction
+
+``ConfigNode``s store individual mutations in order to be able to update other,
+out of date ``ConfigNode``s without needing to send a full snapshot. Each
+configuration database commit also contains additional metadata such as a
+timestamp and a text description of the changes being made. To keep the size of
+the configuration database manageable, a compaction process runs periodically
+(defaulting to every five minutes) which compacts individual mutations into a
+simplified snapshot of key-value pairs. Compaction is controlled by the
+``ConfigBroadcaster``, using information it peridiodically requests from
+``ConfigNode``s. Compaction will only compact up to the minimum known version
+across *all* ``ConfigNode``s. This means that if one ``ConfigNode`` is
+permanently partitioned from the ``ConfigBroadcaster`` or from clients, no
+compaction will ever take place.
+
+### Rollback / Rollforward
+
+It is necessary to be able to roll ``ConfigNode``s backward and forward with
+respect to their committed versions due to the nature of quorum logic and
+unreliable networks.
+
+Consider a case where a client commit gets persisted durably on one out of
+three ``ConfigNode``s (assume commit messages to the other two nodes are lost).
+Since the value is not committed on a majority of ``ConfigNode``s, it cannot be
+considered committed. But it is also incorrect to have the value persist on one
+out of three nodes as future commits are made. In this case, the most common
+result is that the ``ConfigNode`` will be rolled back when the next commit from
+a different client is made, and then rolled forward to contain the data from
+the commit. ``PaxosConfigConsumer`` contains logic to recognize ``ConfigNode``
+minorities and update them to match the quorum.
+
+### Changing Coordinators
+
+Since the configuration database lives on the coordinators and the
+[coordinators can be
+changed](https://apple.github.io/foundationdb/configuration.html#configuration-changing-coordination-servers),
+it is necessary to copy the configuration database from the old to the new
+coordinators during such an event. A coordinator change performs the following
+steps in regards to the configuration database:
+
+1. Write ``\xff/coordinatorsKey`` with the new coordinators string. The key
+   ``\xff/previousCoordinators`` contains the current (old) set of
+   coordinators.
+2. Lock the old ``ConfigNode``s so they can no longer serve client requests.
+3. Start a recovery, causing a new cluster controller (and therefore
+   ``ConfigBroadcaster``) to be selected.
+4. Read ``\xff/previousCoordinators`` on the ``ConfigBroadcaster`` and, if
+   present, read an up-to-date snapshot of the configuration database on the
+   old coordinators.
+5. Determine if each registering ``ConfigNode`` needs an up-to-date snapshot of
+   the configuration database sent to it, based on its reported version and the
+   snapshot version of the database received from the old coordinators.
+   * Some new coordinators which were also coordinators in the previous
+     configuration may not need a snapshot.
+6. Send ready requests to new ``ConfigNode``s, including an up-to-date snapshot
+   if necessary. This allows the new coordinators to begin serving
+   configuration database requests from clients.
+
+## Testing
+
+The ``ConfigDatabaseUnitTests`` class unit test a number of different
+configuration database dimensions.
+
+The ``ConfigIncrement`` workload tests contention between clients attempting to
+write to the configuration database, paired with machine failure and
+coordinator changes.

Subject: [PATCH 0827/1244] Fixed a few bugs which caused ratekeeper to
 unnecessarily throttle a cluster (#8006)

* do not count recently created change feeds for throttling

* fix: blocked assignments were not decremented when force purging

* fix: created needs to be updated when the changefeed is reset

* added asserts to detect if ratekeeper is throttled on blob workers

Subject: [PATCH 0831/1244] Make envvar access in envvar-knob parsing
 cross-platform (#7999)

* Make envvar access in envvar-knob parsing cross-platform

Variable `environ' is defined for Linux,
does not exist in Mac, and is deprecated in Windows

* Prevent env knob strings from being copied at each iteration

* Add headers for {Get|Free}EnvironmentStrings()

* Adjust for different memory layout of environ vs GetEnvironmentStrings()

GetEnvironmentStrings returns a single byte string
with adjacent key=value strings delimited with null bytes,
whereas environ is an array of key=value strings.

* Fix missing return value for Windows build

* Have just one return statement

* fix: blocked assignments were not decremented when force purging

* fix: created needs to be updated when the changefeed is reset

* added asserts to detect if ratekeeper is throttled on blob workers

* fix: the cluster controller did not halt singletons if their role wait failure client triggered but their worker wait failure client did not trigger

 On the ratekeeper, every `SERVER_KNOBS->TAG_THROTTLE_PUSH_INTERVAL` seconds, the ratekeeper will call `GlobalTagThrottler::getClientRates`. At the end of the rate calculation for each tag, a trace event of type `GlobalTagThrottler_GotClientRate` is produced. This trace event reports the relevant inputs that went in to the rate calculation, and can be used for debugging.
 
 On storage servers, every `SERVER_KNOBS->TAG_MEASUREMENT_INTERVAL` seconds, there are `BusyReadTag` events for every tag that has sufficient read cost to be reported to the ratekeeper. Both cost and fractional busyness are reported.

-For each storage server, the busiest read tag is reported in the full status output, along with its cost and fractional busyness.

-At path `.cluster.qos.global_tag_throttler`, throttling limitations for each tag are reported:

Subject: [PATCH 0870/1244] KeyRangeMap: introduce Unaligned KeyRangMap
 functions

This allows us to return:
[firstKey, transition points, endKey]
where firstKey <= keys.begin and endKey >= keys.end.

This also fixes a prior issue where we were ending the range with a
larger key's value rather than carrying the largest value within the
range to the end.

Subject: [PATCH 0877/1244] Support Redwood encryption (#7376)

A new knob `ENABLE_STORAGE_SERVER_ENCRYPTION` is added, which despite its name, currently only Redwood supports it. The knob is mean to be only used in tests to test encryption in individual components, and otherwise enabling encryption should be done through the general `ENABLE_ENCRYPTION` knob.

Under the hood, a new `Encryption` encoding type is added to `IPager`, which use AES-256 to encrypt a page. With this encoding, `BlobCipherEncryptHeader` is inserted into page header for encryption metadata. Moreover, since we compute and store an SHA-256 auth token with the encryption header, we rely on it to checksum the data (and the encryption header), and skip the standard xxhash checksum.

`EncryptionKeyProvider` implements the `IEncryptionKeyProvider` interface to provide encryption keys, which utilizes the existing `getLatestEncryptCipherKey` and `getEncryptCipherKey` actors to fetch encryption keys from either local cache or EKP server. If multi-tenancy is used, for writing a new page, `EncryptionKeyProvider` checks if a page contain only data for a single tenant, if so, fetches tenant specific encryption key; otherwise system encryption key is used. The tenant check is done by extracting tenant id from page bound key prefixes. `EncryptionKeyProvider` also holds a reference of the `tenantPrefixIndex` map maintained by storage server, which is used to check if a tenant do exists, and getting the tenant name in order to get the encryption key.

+    This is the central configuration class for test harness. The values in this class are exposed globally through
+    a global variable test_harness.config.config. This class provides some "magic" to keep test harness flexible.
+    Each parameter can further be configured using an `_args` member variable which is expected to be a dictionary.
+    * The value of any variable can be set through the command line. For a variable named `variable_name` we will
+      by default create a new command line option `--variable-name` (`_` is automatically changed to `-`). This
+      default can be changed by setting the `'long_name'` property in the `_arg` dict.
+    * In addition the user can also optionally set a short-name. This can be achieved by setting the `'short_name'`
+      property in the `_arg` dictionary.
+    * All additional properties in `_args` are passed to `argparse.add_argument`.
+    * If the default of a variable is `None` the user should explicitly set the `'type'` property to an appropriate
+      type.
+    * In addition to command line flags, all configuration options can also be controlled through environment variables.
+      By default, `variable-name` can be changed by setting the environment variable `TH_VARIABLE_NAME`. This default
+      can be changed by setting the `'env_name'` property.
+    * Test harness comes with multiple executables. Each of these should use the config facility. For this,
+      `Config.build_arguments` should be called first with the `argparse` parser. Then `Config.extract_args` needs
+      to be called with the result of `argparse.ArgumentParser.parse_args`. A sample example could look like this:
+      ```
+      parser = argparse.ArgumentParser('TestHarness', formatter_class=argparse.ArgumentDefaultsHelpFormatter)
+      config.build_arguments(parser)
+      args = parser.parse_args()
+      config.extract_args(args)
+      ```
+    * Changing the default value for all executables might not always be desirable. If it should be only changed for
+      one executable Config.change_default should be used.

+# Dynamic Knobs
+
+This document is largely adapted from original design documents by Markus
+Pilman and Trevor Clinkenbeard.
+
+## Background
+
+FoundationDB parameters control the behavior of the database, including whether
+certain features are available and the value of internal constants. Parameters
+will be referred to as knobs for the remainder of this document. Currently,
+these knobs are configured through arguments passed to `fdbserver` processes,
+often controlled by `fdbmonitor`. This has a number of problems:
+
+1. Updating knobs involves updating `foundationdb.conf` files on each host in a
+   cluster. This has a lot of overhead and typically requires external tooling
+   for large scale changes.
+2. All knob changes require a process restart.
+3. We can't easily track the history of knob changes.
+
+## Overview
+
+The dynamic knobs project creates a strictly serializable quorum-based
+configuration database stored on the coordinators. Each `fdbserver` process
+specifies a configuration path and applies knob overrides from the
+configuration database for its specified classes.
+
+### Caveats
+
+The configuration database explicitly does not support the following:
+
+1. A high load. The update rate, while not specified, should be relatively low.
+2. A large amount of data. The database is meant to be relatively small (under
+   one megabyte). Data is not sharded and every coordinator stores a complete
+   copy.
+3. Concurrent writes. At most one write can succeed at a time, and clients must
+   retry their failed writes.
+
+## Design
+
+### Configuration Path
+
+Each `fdbserver` process can now include a `--config_path` argument specifying
+its configuration path. A configuration path is a hierarchical list of
+configuration classes specifying which knob overrides the `fdbserver` process
+should apply from the configuration database. For example:
+
+```bash
+$ fdbserver --config_path classA/classB/classC ...
+```
+
+Knob overrides follow descending priority:
+
+1. Manually specified command line knobs.
+2. Individual configuration class overrides.
+  * Subdirectories override parent directories. For example, if the
+    configuration path is `az-1/storage/gp3`, the `gp3` configuration takes
+    priority over the `storage` configuration, which takes priority over the
+    `az-1` configuration.
+3. Global configuration knobs.
+4. Default knob values.
+
+#### Example
+
+For example, imagine an `fdbserver` process run as follows:
+
+```bash
+$ fdbserver --datadir /mnt/fdb/storage/4500 --logdir /var/log/foundationdb --public_address auto:4500 --config_path az-1/storage/gp3 --knob_disable_asserts false
+```
+
+And the configuration database contains:
+
+| ConfigClass | KnobName            | KnobValue |
+|-------------|---------------------|-----------|
+| az-2        | page_cache_4k       | 8e9       |
+| storage     | min_trace_severity  | 20        |
+| az-1        | compaction_interval | 280       |
+| storage     | compaction_interval | 350       |
+| az-1        | disable_asserts     | true      |
+| \<global\>  | max_metric_size     | 5000      |
+| gp3         | max_metric_size     | 1000      |
+
+The final configuration for the process will be:
+
+| KnobName            |  KnobValue  | Explanation |
+|---------------------|-------------|-------------|
+| page_cache_4k       | \<default\> | The configuration database knob override for `az-2` is ignored, so the compiled default is used |
+| min_trace_severity  | 20          | Because the `storage` configuration class is part of the process’s configuration path, the corresponding knob override is applied from the configuration database |
+| compaction_interval | 350         | The `storage` knob override takes precedence over the `az-1` knob override |
+| disable_asserts     | false       | This knob is manually overridden, so all other overrides are ignored |
+| max_metric_size     | 1000        | Knob overrides for specific configuration classes take precedence over global knob overrides, so the global override is ignored |
+
+### Clients
+
+Clients can write to the configuration database using transactions.
+Configuration database transactions are differentiated from regular
+transactions through specification of the `USE_CONFIG_DATABASE` database
+option.
+
+In configuration transactions, the client uses the tuple layer to interact with
+the configuration database. Keys are tuples of size two, where the first item
+is the configuration class being written, and the second item is the knob name.
+The value should be specified as a string. It will be converted to the
+appropriate type based on the declared type of the knob being set.
+
+Below is a sample Python script to write to the configuration database.
+
+```python
+import fdb
+
+fdb.api_version(720)
+
+@fdb.transactional
+def set_knob(tr, knob_name, knob_value, config_class, description):
+        tr['\xff\xff/description'] = description
+        tr[fdb.tuple.pack((config_class, knob_name,))] = knob_value
+
+# This function performs two knob changes transactionally.
+@fdb.transactional
+def set_multiple_knobs(tr):
+        tr['\xff\xff/description'] = 'description'
+        tr[fdb.tuple.pack((None, 'min_trace_severity',))] = '10'
+        tr[fdb.tuple.pack(('az-1', 'min_trace_severity',))] = '20'
+
+db = fdb.open()
+db.options.set_use_config_database()
+
+set_knob(db, 'min_trace_severity', '10', None, 'description')
+set_knob(db, 'min_trace_severity', '20', 'az-1', 'description')
+```
+
+### Disable the Configuration Database
+
+The configuration database includes both client and server changes and is
+enabled by default. Thus, to disable the configuration database, changes must
+be made to both.
+
+#### Server
+
+The configuration database can be disabled by specifying the ``fdbserver``
+command line option ``--no-config-db``. Note that this option must be specified
+for *every* ``fdbserver`` process.
+
+#### Client
+
+The only client change from the configuration database is as part of the change
+coordinators command. The change coordinators command is not considered
+successful until the configuration database is readable on the new
+coordinators. This will cause the change coordinators command to hang if run
+against a database with dynamic knobs disabled. To disable the client side
+configuration database liveness check, specify the ``--no-config-db`` flag when
+changing coordinators. For example:
+
+```
+fdbcli> coordinators auto --no-config-db
+```
+
+## Status
+
+The current state of the configuration database is output as part of `status
+json`. The configuration path for each process can be determined from the
+``command_line`` key associated with each process.
+
+Sample from ``status json``:
+
+```
+"configuration_database" : {
+    "commits" : [

+            "description" : "set some knobs",

+            "timestamp" : 1659570000,

+            "knob_name" : "compaction_interval",

+        },
+        {
+            "config_class" : "az-1",
+            "knob_name" : "compaction_interval",
+            "knob_value" : "double:60.000000",
+            "type" : "set",
+            "version" : 1
+        },
+        {

+            "type" : "clear",
+            "version" : 2
+        },
+        {
+            "config_class" : "<global>",
+            "knob_name" : "update_node_timeout",
+            "knob_value" : "double:4.000000",
+            "type" : "set",

+        }
+    ],
+    "snapshot" : {

+            "update_node_timeout" : "double:4.000000"
+        },
+        "az-1" : {
+            "compaction_interval" : "double:60.000000"
+        }
+    }
+}
+```
+
+After compaction, ``status json`` would show:
+
+```
+"configuration_database" : {
+    "commits" : [
+    ],
+    "last_compacted_version" : 2,
+    "most_recent_version" : 2,
+    "mutations" : [
+    ],
+    "snapshot" : {
+        "<global>" : {
+            "min_trace_severity" : "int:5",
+            "update_node_timeout" : "double:4.000000"
+        },
+        "az-1" : {
+            "compaction_interval" : "double:60.000000"
+        }
+    }
+}
+```
+
+## Detailed Implementation
+
+The configuration database is implemented as a replicated state machine living
+on the coordinators. This allows configuration database transactions to
+continue to function in the event of a catastrophic loss of the transaction
+subsystem.
+
+To commit a transaction, clients run the two phase Paxos protocol. First, the
+client asks for a live version from a quorum of coordinators. When a
+coordinator receives a request for its live version, it increments its local
+live version by one and returns it to the client. Then, the client submits its
+writes at the live version it received in the previous step. A coordinator will
+accept the commit if it is still on the same live version. If a majority of
+coordinators accept the commit, it is considered committed.
+
+### Coordinator
+
+Each coordinator runs a ``ConfigNode`` which serves as a replica storing one
+full copy of the configuration database. Coordinators never communicate with
+other coordinators while processing configuration database transactions.
+Instead, the client runs the transaction and determines when it has quorum
+agreement.
+
+Coordinators serve the following ``ConfigTransactionInterface`` to allow
+clients to read from and write to the configuration database.
+
+#### ``ConfigTransactionInterface``

+| GetConfigClasses | (coordinatorsHash, generation)                                 | (configuration classes) or (coordinators_changed error) or (transaction_too_old error)        | Returns a list of all configuration classes stored in the configuration database                                 |
+| GetKnobs         | (configuration class, coordinatorsHash, generation)            | (knob names) or (coordinators_changed error) or (transaction_too_old error)                   | Returns a list of all knob names stored for the provided configuration class                                     |

+
+Coordinators also serve the following ``ConfigFollowerInterface`` to provide
+access to (and modification of) their current state. Most interaction through
+this interface is done by the cluster controller through its
+``IConfigConsumer`` implementation living on the ``ConfigBroadcaster``.

+
+### Cluster Controller
+
+The cluster controller runs a singleton ``ConfigBroadcaster`` which is
+responsible for periodically polling the ``ConfigNode``s for updates, then
+broadcasting these updates to workers through the ``ConfigBroadcastInterface``.
+When workers join the cluster, they register themselves and their
+``ConfigBroadcastInterface`` with the broadcaster. The broadcaster then pushes
+new updates to registered workers.
+
+The ``ConfigBroadcastInterface`` is also used by ``ConfigNode``s to register
+with the ``ConfigBroadcaster``. ``ConfigNode``s need to register with the
+broadcaster because the broadcaster decides when the ``ConfigNode`` may begin
+serving requests, based on global information about status of other
+``ConfigNode``s. For example, if a system with three ``ConfigNode``s suffers a
+fault where one ``ConfigNode`` loses data, the faulty ``ConfigNode``  should
+not be allowed to begin serving requests again until it has been rolled forward
+and is up to date with the latest state of the configuration database.
+
+#### ``ConfigBroadcastInterface``

+| Ready      | (snapshot, snapshotVersion, liveVersion, coordinatorsHash) | ack                           | Sent by the broadcaster to new ``ConfigNode``s to allow them to start serving requests      |
+
+### Worker
+
+Each worker runs a ``LocalConfiguration`` instance which receives and applies
+knob updates from the ``ConfigBroadcaster``. The local configuration maintains
+a durable ``KeyValueStoreMemory`` containing the following:
+
+* The latest known configuration version
+* The most recently used configuration path
+* All knob overrides corresponding to the configuration path at the latest known version
+
+Once a worker starts, it will:
+
+* Apply manually set knobs
+* Read its local configuration file
+  * If the stored configuration path does not match the configuration path
+    specified on the command line, delete the local configuration file
+  * Otherwise, apply knob updates from the local configuration file. Manually
+    specified knobs will not be overridden
+  * Register with the broadcaster to receive new updates for its configuration
+    classes
+    * Persist these updates when received and restart if necessary
+
+### Knob Atomicity
+
+All knobs are classified as either atomic or non-atomic. Atomic knobs require a
+process restart when changed, while non-atomic knobs do not.
+
+### Compaction
+
+``ConfigNode``s store individual mutations in order to be able to update other,
+out of date ``ConfigNode``s without needing to send a full snapshot. Each
+configuration database commit also contains additional metadata such as a
+timestamp and a text description of the changes being made. To keep the size of
+the configuration database manageable, a compaction process runs periodically
+(defaulting to every five minutes) which compacts individual mutations into a
+simplified snapshot of key-value pairs. Compaction is controlled by the
+``ConfigBroadcaster``, using information it peridiodically requests from
+``ConfigNode``s. Compaction will only compact up to the minimum known version
+across *all* ``ConfigNode``s. This means that if one ``ConfigNode`` is
+permanently partitioned from the ``ConfigBroadcaster`` or from clients, no
+compaction will ever take place.
+
+### Rollback / Rollforward
+
+It is necessary to be able to roll ``ConfigNode``s backward and forward with
+respect to their committed versions due to the nature of quorum logic and
+unreliable networks.
+
+Consider a case where a client commit gets persisted durably on one out of
+three ``ConfigNode``s (assume commit messages to the other two nodes are lost).
+Since the value is not committed on a majority of ``ConfigNode``s, it cannot be
+considered committed. But it is also incorrect to have the value persist on one
+out of three nodes as future commits are made. In this case, the most common
+result is that the ``ConfigNode`` will be rolled back when the next commit from
+a different client is made, and then rolled forward to contain the data from
+the commit. ``PaxosConfigConsumer`` contains logic to recognize ``ConfigNode``
+minorities and update them to match the quorum.
+
+### Changing Coordinators
+
+Since the configuration database lives on the coordinators and the
+[coordinators can be
+changed](https://apple.github.io/foundationdb/configuration.html#configuration-changing-coordination-servers),
+it is necessary to copy the configuration database from the old to the new
+coordinators during such an event. A coordinator change performs the following
+steps in regards to the configuration database:
+
+1. Write ``\xff/coordinatorsKey`` with the new coordinators string. The key
+   ``\xff/previousCoordinators`` contains the current (old) set of
+   coordinators.
+2. Lock the old ``ConfigNode``s so they can no longer serve client requests.
+3. Start a recovery, causing a new cluster controller (and therefore
+   ``ConfigBroadcaster``) to be selected.
+4. Read ``\xff/previousCoordinators`` on the ``ConfigBroadcaster`` and, if
+   present, read an up-to-date snapshot of the configuration database on the
+   old coordinators.
+5. Determine if each registering ``ConfigNode`` needs an up-to-date snapshot of
+   the configuration database sent to it, based on its reported version and the
+   snapshot version of the database received from the old coordinators.
+   * Some new coordinators which were also coordinators in the previous
+     configuration may not need a snapshot.
+6. Send ready requests to new ``ConfigNode``s, including an up-to-date snapshot
+   if necessary. This allows the new coordinators to begin serving
+   configuration database requests from clients.
+
+## Testing
+
+The ``ConfigDatabaseUnitTests`` class unit test a number of different
+configuration database dimensions.
+
+The ``ConfigIncrement`` workload tests contention between clients attempting to
+write to the configuration database, paired with machine failure and
+coordinator changes.

+API Tester
+##########
+
+Introduction
+============
+
+API tester is a framework for implementing end-to-end tests of FDB C API, i.e. testing the API on a real
+FDB cluster through all layers of the FDB client. Its executable is ``fdb_c_api_tester``, and the source
+code is located in ``bindings/c/test/apitester``. The structure of API Tests is similar to that of the 
+Simulation Tests. The tests are implemented as workloads using FDB API, which are all built into the 
+``fdb_c_api_tester``. A concrete test configuration is defined as a TOML file, which specifies the
+combination of workloads to be executed by the test together with their parameters. The test can be then
+executed by passing the TOML file as a parameter to ``fdb_c_api_tester``. 
+
+Since simulation tests rely on the actor model to execute the tests deterministically in single-threaded
+mode, they are not suitable for testing various multi-threaded aspects of the FDB client. End-to-end API
+tests complement the simulation tests by testing the FDB Client layers above the single-threaded Native
+Client. 
+
+- The specific testing goals of the end-to-end tests are:
+- Check functional correctness of the Multi-Version Client (MVC) and Thread-Safe Client 
+- Detecting race conditions. They can be caused by accessing the state of the Native Client from wrong
+  threads or introducing other shared state without proper synchronization
+- Detecting memory management errors. Thread-safe reference counting must be used where necessary. MVC
+  works with multiple client libraries. Memory allocated by one client library must be also deallocated
+  by the same library.
+- Maintaining interoperability with other client versions.  The client functionality is made available
+  depending on the selected API version. The API changes are correctly adapted. 
+- Client API behaves correctly in case of cluster upgrades. Database and transaction state is correctly
+  migrated to the upgraded connections. Pending operations are canceled and successfully retried on the
+  upgraded connections.
+
+Implementing a Workload
+=======================
+
+Each workload is declared as a direct or indirect subclass of ``WorkloadBase`` implementing a constructor
+with ``WorkloadConfig`` as a parameter and the method ``start()``, which defines the entry point of the
+workload. 
+
+``WorkloadBase`` provides a set of methods that serve as building blocks for implementation of a workload:
+
+.. function:: execTransaction(start, cont, failOnError = true)
+
+   creates and executes an FDB transaction. Here ``start`` is a function that takes a transaction context
+   as parameter and implements the starting point of the transaction, and ``cont`` is a function implementing
+   a continuation to be executed after finishing the transaction execution. Transactions are automatically
+   retried on retryable errors. Transactions are retried by calling the ``start`` function again. In case
+   of a fatal error, the entire workload is considered as failed unless ``failOnError`` is set to ``false``.
+
+.. function:: schedule(task)
+
+   schedules a task for asynchronous execution. It is usually used in the continuations to schedule 
+   the next step of the workload.
+
+.. function:: info(msg) 
+              error(msg) 
+              
+   are used for logging a message with a tag identifying the workload. Issuing an error message marks
+   the workload as failed.
+
+The transaction context provides methods for implementation of the transaction logics:
+
+.. function:: tx()
+   
+   the reference to the FDB transaction object
+
+.. function:: continueAfter(future, cont, retryOnError = true)
+   
+   set a continuation to be executed when the future is ready. The ``retryOnError`` flag controls whether
+   the transaction should be automatically retried in case the future results in a retriable error.
+
+.. function:: continueAfterAll(futures, cont)
+   
+   takes a vector of futures and sets a continuation to be executed when all of the futures get ready.
+   The transaction is retried if at least one of the futures results in an error. This method is useful 
+   for handling multiple concurrent reads.
+
+.. function:: commit() 
+   
+   commit and finish the transaction. If the commit is successful, the execution proceeds to the
+   continuation of ``execTransaction()``. In case of a retriable error the transaction is
+   automatically retried. A fatal error results in a failure of the workoad.
+
+
+.. function:: done() 
+   
+   finish the transaction without committing. This method should be used to finish read transactions. 
+   The transaction gets destroyed and execution proceeds to the continuation of ``execTransaction()``.
+   Each transaction must be finished either by ``commit()`` or ``done()``, because otherwise
+   the framework considers that the transaction is still being executed, so it won't destroy it and
+   won't call the continuation.
+
+.. function:: onError(err) 
+   
+   Handle an error: restart the transaction in case of a retriable error, otherwise fail the workload.
+   This method is typically used in the continuation of ``continueAfter`` called with
+   ``retryOnError=false`` as a fallback to the default error handling.
+
+A workload execution ends automatically when it is marked as failed or its last continuation does not
+schedule any new task or transaction. 
+
+The workload class should be defined in the namespace FdbApiTester. The file name convention is
+``Tester{Name}Workload.cpp`` so that we distinguish them from the source files of simulation workloads.
+
+Basic Workload Example
+======================
+
+The code below implements a workload that consists of only two transactions. The first one sets a
+randomly generated key to a randomly generated value, and the second one reads the key and checks if
+the returned value matches the written one.
+
+.. literalinclude:: ../../../bindings/c/test/apitester/TesterExampleWorkload.cpp
+   :language: C++
+   :lines: 21-
+
+The workload is implemented in the method ``setAndGet``. It generates a random key and a random value
+and executes a transaction that writes that key-value pair and commits. In the continuation of the
+first ``execTransaction`` call, we execute the second transaction that reads the same key. The read
+operation returns a future. So we call ``continueAfter`` to set a continuation for that future. In the
+continuation we check if the returned value matches the written one and finish the transaction by
+calling ``ctx->done()``. After completing the second transaction we execute the continuation passed
+as parameter to the ``setAndGet`` method by the start method. In this case it is ``NO_OP_TASK``, which
+does nothing and so finishes the workload.
+
+Finally, we declare an instance ``WorkloadFactory`` to register this workload with the name ``SetAndGet``.
+
+Note that we use ``workloadId`` as a key prefix. This is necessary for isolating the key space of this
+workload, because the framework may be instructed to create multiple instances of the ``SetAndGet``
+workload. If we do not isolate the key space, another workload can write a different value for the
+same key and so break the assumption of the test.
+
+The workload is implemented using the internal C++ API, implemented in ``fdb_api.hpp``. It introduces
+a set of classes representing the FDB objects (transactions, futures, etc.). These classes provide C++-style 
+methods wrapping FDB C API calls and automate memory management by means of reference counting.
+
+Implementing Control Structures
+===============================
+
+Our basic workload executes just 2 transactions, but in practice we want to have workloads that generate
+multiple transactions. The following code demonstrates how we can modify our basic workload to generate
+multiple transactions in a loop. 
+
+.. code-block:: C++
+
+   class SetAndGetWorkload : public WorkloadBase {
+   public:
+      ...
+      int numIterations;
+      int iterationsLeft;
+
+      SetAndGetWorkload(const WorkloadConfig& config) : WorkloadBase(config) {
+         keyPrefix = fdb::toBytesRef(fmt::format("{}/", workloadId));
+         numIterations = config.getIntOption("numIterations", 1000);
+      }
+
+      void start() override {
+         iterationsLeft = numIterations;
+         setAndGetLoop();
+      }
+
+      void setAndGetLoop() {
+         if (iterationsLeft == 0) {
+            return;
+         }
+         iterationsLeft--;
+         setAndGet([this]() { setAndGetLoop(); });
+      }
+      ...
+   }
+
+We introduce a workload parameter ``numIterations`` to specify the number of iterations. If not specified
+in the test configuration it defaults to 1000.
+
+The method ``setAndGetLoop`` implements the loop that decrements iterationsLeft counter until it reaches 0
+and each iteration calls setAndGet with a continuation that returns the execution to the loop. As you
+can see we don't need any change in ``setAndGet``, just call it with another continuation. 
+
+The pattern of passing a continuation as a parameter also can be used to decompose the workload into a
+sequence of steps. For example,  we can introduce setup and cleanUp steps to our workload and modify the
+``setAndGetLoop`` to make it composable with an arbitrary continuation:
+
+.. code-block:: C++
+
+    void start() override {
+       setup([this](){
+           iterationsLeft = numIterations;
+           setAndGetLoop([this](){
+               cleanup(NO_OP_TASK);
+           });
+       });
+    }
+
+    void setAndGetLoop(TTaskFct cont) {
+       if (iterationsLeft == 0) {
+           schedule(cont);
+       }
+       iterationsLeft--;
+       setAndGet([this, cont]() { setAndGetLoop(cont); });
+   }
+
+   void setup(TTaskFct cont) { ... }
+
+   void cleanup(TTaskFct cont) {  ... }
+
+Note that we call ``schedule(cont)`` in ``setAndGetLoop`` instead of calling the continuation directly.
+In this way we avoid keeping ``setAndGetLoop`` in the call stack, when executing the next step.
+
+Subclassing ApiWorkload
+=======================
+
+``ApiWorkload`` is an abstract subclass of ``WorkloadBase`` that provides a framework for a typical
+implementation of API test workloads. It implements a workflow consisting of cleaning up the key space
+of the workload, populating it with newly generated data and then running a loop consisting of random
+database operations. The concrete subclasses of ``ApiWorkload`` are expected to override the method
+``randomOperation`` with an implementation of concrete random operations.
+
+The ``ApiWorkload`` maintains a local key-value store that mirrors the part of the database state
+relevant to the workload. A successful database write operation should be followed by a continuation
+that performs equivalent changes in the local store, and the results of a database read operation should
+be validated against the values from the local store. 
+
+Test Configuration
+==================
+
+A concrete test configuration is specified by a TOML file. The file must contain one ``[[test]]`` section
+specifying the general settings for test execution followed by one or more ``[[test.workload]]``
+configuration sessions, specifying the workloads to be executed and their parameters. The specified
+workloads are started all at once and executed concurrently.
+
+The ``[[test]]`` section can contain the following options:
+
+- ``title``: descriptive title of the test
+- ``multiThreaded``: enable multi-threading (default: false)
+- ``minFdbThreads`` and ``maxFdbThreads``: the number of FDB (network) threads to be randomly selected
+  from the given range (default: 1-1). Used only if ``multiThreaded=true``. It is also important to use
+  multiple database instances to make use of the multithreading.
+- ``minDatabases`` and ``maxDatabases``: the number of database instances to be randomly selected from
+  the given range (default 1-1). The transactions of all workloads are randomly load-balanced over the
+  pool of database instances.
+- ``minClients`` and ``maxClients``: the number of clients, i.e. instances of each workload, to be
+  randomly selected from the given range (default 1-8).
+- ``minClientThreads`` and ``maxClientThreads``: the number of client threads, i.e. the threads used
+  for execution of the workload, to be randomly selected from the given range (default 1-1).
+- ``blockOnFutures``: use blocking waits on futures instead of scheduling future callbacks asynchronously
+  (default: false)
+- ``buggify``: Enable client-side failure injection (default: false)
+- ``databasePerTransaction``: Create a separate database instance for each transaction (default: false).
+  It is a special mode useful for testing bugs related to creation and destruction of database instances. 
+- ``fdbCallbacksOnExternalThreads``: Enables the option ``FDB_NET_OPTION_CALLBACKS_ON_EXTERNAL_THREADS``
+  causting the callbacks of futures to be executed directly on the threads of the external FDB clients 
+  rather than on the thread of the local FDB client. 
+
+The workload section ``[[test.workload]]`` must contain the attribute name matching the registered name
+of the workload to be executed. Other options are workload-specific. 
+
+The subclasses of the ``ApiWorkload`` inherit the following configuration options:
+
+- ``minKeyLength`` and ``maxKeyLength``: the size range of randomly generated keys (default: 1-64)
+- ``minValueLength`` and ``maxValueLength``:  the size range of randomly generated values 
+  (default: 1-1000)
+- ``maxKeysPerTransaction``: the maximum number of keys per transaction (default: 50)
+- ``initialSize``: the number of key-value pairs in the initially populated database (default: 1000)
+- ``readExistingKeysRatio``: the probability of choosing an existing key for read operations 
+  (default: 0.9)
+- ``numRandomOperations``: the number of random operations to be executed per workload (default: 1000)
+- ``runUntilStop``: run the workload indefinitely until the stop command is received (default: false).
+   This execution mode in upgrade tests and other scripted tests, where the workload needs to
+   be generated continously until completion of the scripted test.
+- ``numOperationsForProgressCheck``: the number of operations to be performed to confirm a progress 
+   check (default: 10). This option is used in combination with ``runUntilStop``. Progress checks are
+   initiated by a test script to check if the client workload is successfully progressing after a
+   cluster change.
+
+Executing the Tests
+===================
+
+The ``fdb_c_api_tester`` executable takes a single TOML file as a parameter and executes the test
+according to its specification. Before that we must create a FDB cluster and pass its cluster file as
+a parameter to ``fdb_c_api_tester``. Note that multithreaded tests also need to be provided with an
+external client library. 
+
+For example, we can create a temporary cluster and use it for execution of one of the existing API tests:
+
+.. code-block:: bash
+
+   ${srcDir}/tests/TestRunner/tmp_cluster.py --build-dir ${buildDir} -- \
+      ${buildDir}/bin/fdb_c_api_tester \
+      --cluster-file @CLUSTER_FILE@ \
+      --external-client-library=${buildDir}/bindings/c/libfdb_c_external.so \
+      --test-file ${srcDir}/bindings/c/test/apitester/tests/CApiCorrectnessMultiThr.toml
+
+The test specifications added to the ``bindings/c/test/apitester/tests/`` directory are executed as a part
+of the regression test suite. They can be executed using the ``ctest`` target ``fdb_c_api_tests``:
+
+.. code-block:: bash
+   
+   ctest -R fdb_c_api_tests -VV

+``three_data_hall_fallback`` mode
+    FoundationDB stores data in duplicate, with one copy each on a storage server in two of three data halls. The transaction logs are replicated four times, with two data halls containing two replicas apiece. Four available machines (two in each of two data halls) are therefore required to make progress. This configuration is similar to ``three_data_hall``, differing only in that data is stored on two instead of three replicas. This configuration is useful to unblock data distribution when a data hall becomes temporarily unavailable. Because ``three_data_hall_fallback`` reduces the redundancy level to two, it should only be used as a temporary measure to restore cluster health during a datacenter outage.

+# Set up the Azure Backup Testing Environment
+
+Make sure we built FDB with `-DBUILD_AZURE_BACKUP=ON`
+
+# Test
+
+If you run _BackupToBlob_ and _RestoreFromBlob_ workloads with the paramter _backupURL_ starts with `azure://`,
+the workload will backup to and restore from the azure blob storage.
+For example, _BackupAzureBlobCorrectness.toml_
+
+## Url format
+
+The code now supports the following style urls:
+
+- `azure://<account_name>.blob.core.windows.net/<container_name>` (The formal url format for the blob service provided by the azure storage account)
+- `azure://<ip|hostname>:<port>/<account_name>/<container_name>` (Directly providing the endpoint address for the blob service, usually for local testing)
+
+## Local test environment 
+
+We need to use the _Azurite_ to simulate an Azure blob service locally.
+Please follow the [turtorial](https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azurite?tabs=docker-hub) to start your service locally.
+
+For example,
+```
+docker run -p 10000:10000 -v `pwd`:<path> -w <path> mcr.microsoft.com/azure-storage/azurite azurite-blob --blobHost 0.0.0.0 --blobPort 10000 --oauth basic --cert ./<...>.pem --key ./<...>.key.pem --debug ./<log_file_path>
+```
+
+### Notice
+
+- To use uses _https_, we need to provide the certificates via `--cert` and `--key`
+    The detailed [turtorial](https://github.com/Azure/Azurite/blob/main/README.md#https-setup) to setup HTTPS.  (We tested with the `mkcert` method)
+- To use Azure SDKs, we need to pass `--oauth basic` option
+- Please take a look at the [difference](https://github.com/Azure/Azurite/blob/main/README.md#differences-between-azurite-and-azure-storage) between Azurite and Azure Storage

Subject: [PATCH 0886/1244] Make fdbcli check for TLSConfig and coordinator
 address mismatch

At least one of the coordinator addresses in cluster file must contain ":tls" suffix
if fdbcli's resolved TLS client configuration holds any of the TLS elements (key, cert, or CA)

Conversely, if none of the TLS elements are configured,
at least one of coordinator addresses must be without ":tls" suffix

Subject: [PATCH 0892/1244] Improve memory safety (#8069)

* Move arena members to the end of serializer calls

See
https://github.com/apple/foundationdb/tree/main/flow#flatbuffersobjectserializer
for why this is necessary.

* Fix a heap-use-after-free

Previously memory owned by
EncryptKeyProxyData::baseCipherDomainIdKeyIdCache was borrowed by a call
to EncryptKeyProxyData::insertIntoBaseDomainIdCache where it was
invalidated and then used. Now
EncryptKeyProxyData::insertIntoBaseDomainIdCache takes shared ownership
by taking a Standalone.

And also rename some types to end in Ref to follow the flow conventions
described here: https://github.com/apple/foundationdb/tree/main/flow#arenas

Subject: [PATCH 0893/1244] ClusterCore to handle leader replacement (#8035)

Description

In current code the leader replacement handling is done by
ClusterControllerWatchDog, it is possible that if the cluster
recruitment is in-progress, the leader replacement handling gets
delayed causing the multiple leaders to present simulateneously
impacting cluster recovery.

Move the cluster leader replacement logic to ClusterController
core to avoid above described scenario.

Subject: [PATCH 0895/1244] flow: switch from hard coded to ApiVersion like
 ProtocolVersion (#8071)

* flow: add ApiVersion to replace hard coding api version

Instead of hard coding api value, let's rely on feature versions akin to
ProtocolVersion.

* ApiVersion: remove use of -1 for latest and use LATEST_VERSION

Subject: [PATCH 0901/1244] Encryption data at-rest db-config (#7929)

* Encryption data at-rest db-config

Description

 diff-1: Handle 'force' updates to encryption_at_rest db-config

Major changes proposed:
1. Introduce 'encryption_data_at_rest_mode" 'configure new'
option to enable Encryption data at-rest. The feature is disabled
by default.
2. The configuration is meant to be set at the time of database
creation, addition checks will be done to avoid updating the config
in subsequent PR.
3. DatabaseConfiguration validity check to account for "tenant_mode"
set to `required` if Encryption data at-rest is selected given
EncryptionDomain matches Tenant boundaries.

Testing

Its syntax is ``configure [new|tss] [single|double|triple|three_data_hall|three_datacenter] [ssd|memory] [grv_proxies=<N>] [commit_proxies=<N>] [resolvers=<N>] [logs=<N>] [count=<TSS_COUNT>] [perpetual_storage_wiggle=<WIGGLE_SPEED>] [perpetual_storage_wiggle_locality=<<LOCALITY_KEY>:<LOCALITY_VALUE>|0>] [storage_migration_type={disabled|aggressive|gradual}] [tenant_mode={disabled|optional_experimental|required_experimental}] [encryption_at_rest_mode={aes_256_ctr|disabled}]``.
 
 The ``new`` option, if present, initializes a new database with the given configuration rather than changing the configuration of an existing one. When ``new`` is used, both a redundancy mode and a storage engine must be specified.

Subject: [PATCH 0912/1244] Use distinct base trace file names for client
 threads (#7922)

* Save thread indexes for client instances in MVC

* An option to inlude client thread identifiers into trace file names

* Avoid using new trace file options in client versions not supporting them

* Remove redundant include generated by IDE

* Use different base trace file names for client threads by default. Provide an option to revert to using a shared base file name

* Fixing typos in the description of trace_share_among_client_threads

Subject: [PATCH 0913/1244] Split shards along tenant keyspace boundaries
 (disabled by default) (#7432)

* Boilerplate code for tenant-aware DD

* Add an DD tenant-cache-assembly actor

* Add basic tenant list monitoring for tenant cache. Tenant cache is not yet a DD-scoped structure

* Create a DDTenantCache class

* Move DDTenantCache to new files

* Tweak some traces; fix placement of build and monitor actor invocations

* Update DD tenant cache refresh to be more efficient and unit-testable

* Fix incorrect use of prefixToID in the DDTenantCache code; it is not correct when the tenant is within a tenant subspace

* Fix a faulty assertion in a DDTenantCache unit test, and add a server knob to switch of DDTenantCache code for the moment

* Fix a DDTenantCache UT bug where count of tenants could be 0, causing divide-by-0 exceptions in the test code; Fix accidental movement of atrace statement; rename some DD tenant-cache related variables

* Make some member DDTenantCache member functions const, and change the ddtc abbreviation to ddTenantCache, for ddtc could refer to DDTeamCollection

* Remove unnecessary assertion that erase-ing an element from a Map really removes it

* Remove the DD prefix in the tenant cache class name (and associated impl and UT class names); there is nothing specific to DD in it; DD uses it; other modules may use it in the future

* Disable DD tenant awareness by default

* Split shards along tenant keyspace boundaries

* Update some naming, switch to using prefixRange and fix a bug in tenantShardSplit

* Reorganize tenant shard splitter

* Moved new header file to new include dir under fdbserver

* Make shardEvaluator trigger shard merger only if adjacent shards belong to the same tenant, if tenant-keyspace boundaries are being honored

* Fix issues in the way shard merge decisions are made based on tenant boundaries

* Minor reorg and bug fix in shard merger decision-making

* Resolve merge issues

* Fix bug in ShardEvaluator that made it run in a loop rather than waiting for metrics changes

* Fix tenant splitter for when start and end are in different shards and only one of them needs to be split

* Remove some uses of printable

* Remove uses of printable

* Fix code formatting

* Add a TENANT_SPLIT RelocateReason and fix errors from incorrect merge of upstream code

* Move tenantCreationSignal ownership to TenantCache

* Update fdbserver/DataDistributionTracker.actor.cpp

Co-authored-by: Xiaoxi Wang <xiaoxi.wang@snowflake.com>

* Fix a couple of bugs and spelling errors in tenantShardSplitter

* Update fdbserver/DataDistributionTracker.actor.cpp

Co-authored-by: Xiaoxi Wang <xiaoxi.wang@snowflake.com>

* Refactor split-merge feasibility check methods

* Merge upstream changes

* Break down tenantShardSplitter to remove dependency on DataDistributionTracker and make the splitter unit-testable

* Add unit tests for tenant shard splitting

* Factor out some repeated code when finding tenant boundaries within a shard

* Extract fault line verification steps used in UTs into a separate function

Subject: [PATCH 0915/1244] Rollback #7374

Valgrind is complaining about use of uninitialized memory in
absl::GetStackTrace, and the cases where it complains the backtraces are
incomplete. Note: this means that jemalloc heap profiling no longer
works out of the box. Advanced users who want to enable jemalloc heap
profiling will now have to revert this change and build from source.

Subject: [PATCH 0925/1244] Fix crashes on database create errors (#8115)

* ApiTester: enable access to database instances in workloads

* ApiTester: Inject database create errors

* Fix getClusterProtocol and database shared object initialization in case of database create errors

* Check deferred error in all Thread-Safe API calls returning a future

* ApiTester: disable injection of database create errors for tests with old versions

Subject: [PATCH 0927/1244] Remove API 720 guards for tenants (experimental
 feature) and the cluster ID special keys (#8108)

* Remove API 720 guards for tenants (experimental feature) and the cluster ID special keys (no need to guard)

* Enable the relaxed special key access in transactions that need to use special key-space APIs introduced in 7.2

 Listed below are the special keys that have been deprecated.

Clients specifying older API versions will be able to continue using the deprecated key(s).
 
 #. ``\xff\xff/management/profiling/<client_txn_sample_rate|client_txn_size_limit>`` Deprecated as of API version 720. The corresponding functionalities are now covered by the global configuration module. For details, see :doc:`global-configuration`. Read/write. Changing these two keys will change the corresponding system keys ``\xff\x02/fdbClientInfo/<client_txn_sample_rate|client_txn_size_limit>``, respectively. The value of ``\xff\xff/management/client_txn_sample_rate`` is a literal text of ``double``, and the value of ``\xff\xff/management/client_txn_size_limit`` is a literal text of ``int64_t``. A special value ``default`` can be set to or read from these two keys, representing the client profiling is disabled. In addition, ``clear`` in this range is not allowed. For more details, see help text of ``fdbcli`` command ``profile client``.
-#. ``\xff\xff/management/tenant_map/<tenant>`` Removed as of API version 720 and renamed to ``\xff\xff/management/tenant/map/<tenant>``.

Subject: [PATCH 0950/1244] Add encryption metrics (#8070)

Adding the following metrics:
* BlobCipherKeyCache hit/miss
* EKP: KMS requests latencies
* For each component that using encryption, they now need to pass a UsageType enum to the encryption helper methods (GetEncryptCipherKeys/GetLatestEncryptCipherKey/encrypt/decrypt) and those methods will help to log get cipher key latency samples and encryption/decryption cpu times accordingly.

Subject: [PATCH 0951/1244] Testing with invalid cluster files, fixing update
 from changed cluster file (#8126)

* ApiTester: test with invalid cluster files

* More asserts in monitorProxies

* ApiTester: Test tampering the cluster file

* Fix update of connection string from the cluster file to use the new connection string only if it valid

* ApiTester: add linker dependency on std++fs

* upgrade_test: no-cleanup-on-error option

* ApiTester: use atomic operations to change and access the transaction handle

Subject: [PATCH 0968/1244] Use tls plugin for old binaries < 5.2.0

This fixes restart tests from old binaries < 5.2.0, which previously
were immediately crashing in a TLS codepath. This behavior was not
originally ported from the old test harness to the new test harness.

Subject: [PATCH 0988/1244] bindings: clean up ApiVersion settings

Let's at least clean it up so it's once per file or less and use some
redirection against FDB_API_VERSION or API_VERSION.

Subject: [PATCH 1001/1244] Add flag to disable the configuration database

The `--no-config-db` flag, passed to `fdbserver`, will disable the
configuration database. When this flag is specified, no `ConfigNode`s
will be started, the `ConfigBroadcaster` will not be started, and on a
coordinator change no attempt will be made to lock `ConfigNode`s.

Subject: [PATCH 1002/1244] Add `--no-config-db` option to fdbcli coordinators
 command

Specifying the `--no-config-db` option when changing coordinators
through fdbcli will prevent the command from hanging when the
configuration database is not active. Failing to specify this option
when the configuration database is not active will not affect the
correctness of the command, but it will hang instead of returning.

Subject: [PATCH 1004/1244] Fix various correctness and timeout issues

Contains the following fixes:

* When handling the special case rollforward where nodes can be rolled
  forward even if a majority are at version 0, we don't want to reset
  the live version of the node being rolled forward. This is because a
  quorum of nodes at version 0 can continue handing out and incrementing
  their live version, and if they are rolled forward there is the
  potential for them to go back in time in regard to their live version.
  So in this one special case, they should maintain their existing live
  version.
* Fixes some unseed issues due to fields not being initialized properly.
* Temporarily disables a coordinator restart in the recovery path (in
  the coordinated state) due to it causing a timeout. This needs more
  investigation in the future.

+Authorization
+#############
+
+.. warning :: Authorization is currently experimental and is not recommended for use in production.
+
+Introduction
+============
+
+:ref:`Multi-tenant <multi-tenancy>` database implies a couple of new concepts that did not previously exist in FoundationDB.
+The first is the concept of privilege levels: we have clients whose typical workload is limited to accessing a tenant keyspace.
+On the other hand, we have *administrators* who may read or update cluster-wide configurations through system keyspaces.
+These operations also include creation and deletion of tenants.
+The second is access control: with multiple tenant keyspaces, it comes naturally that we would want to restrict database access of a client to a subset of them.
+
+Privilege Levels
+----------------
+
+Authorization feature extends FoundationDB's existing TLS policy to distinguish administrators from data clients,
+making TLS configuration a prerequisite for enabling authorization.
+There are only two privilege levels: *trusted* versus *untrusted* clients.
+Trusted clients are authorized to perform any operation that pre-authorization FoundationDB clients used to do, including accessing the system keyspace.
+Untrusted clients may only request what is necessary to access tenant keyspaces for which they are authorized.
+Untrusted clients are blocked from accessing anything in the system keyspace or issuing management operations that modifies the cluster in any way.
+
+In order to be considered a trusted client, a client needs to be :ref:`configured with a valid chain of X.509 certificates and keys <enable-TLS>`,
+and its certificate chain must be trusted by the server.
+If the server was configured with trusted IP subnets, i.e. run with one or more ``--trusted-subnet-SUBNET_NAME`` followed by a CIDR block decribing the subnet,
+then the client's IP as seen from the server must also belong to one of the subnets.
+
+Choosing to respond with empty certificate chain during `client authentication <https://www.rfc-editor.org/rfc/rfc5246#section-7.4.6>`_,
+or not belonging to the trusted subnet marks the client as untrusted.
+
+.. note:: Presenting a bad or untrusted certificate chain causes the server to break the connection and eventually throttle the client.
+          It does not let the client connect untrusted.
+
+Access Control
+--------------
+
+To restrict client access only to a pertinent subset of tenant keyspaces, authorization feature allows database administrators
+to grant tenant-scoped access in the form of `JSON Web Tokens <https://www.rfc-editor.org/rfc/rfc7519>`_.
+Token verification is performed against a set of named public keys written in `JWK Set <https://www.rfc-editor.org/rfc/rfc7517#section-5>`_ format.
+A token's header part must contain the key identifier (or `kid <https://www.rfc-editor.org/rfc/rfc7515.html#section-4.1.4>`_) of the public key which shall be used to verify itself.
+Below is the list of token fields recognized by FoundationDB.
+Note that some of the fields are *recognized* by FoundationDB but not actively used in enforcing security, pending future implementation.
+Those fields are marked as *NOT required*.

+Public keys in the set must be either `RSA <https://datatracker.ietf.org/doc/html/rfc7518#section-6.3>`_ public keys
+containing ``n`` and ``e`` parameters, each containing `Base64urlUInt <https://www.rfc-editor.org/rfc/rfc7518#section-2>`_-encoded modulus and exponent.

+`base64url <https://datatracker.ietf.org/doc/html/rfc4648#section-5>`_-encoded affine coordinates.
+In addition, each public key JSON object in set must contain ``kty`` (set to ``EC`` or ``RSA``) field to indicate public key algorithm,
+along with ``kid``, and ``alg`` fields to be compared against their token header counterparts.
+Private keys are strongly recommended against being included in the public key set and, if found, are excluded from consideration.
+
+.. note:: By design, FoundationDB authorization feature does not support revocation of outstanding tokens. Use extra caution in assigning long token durations.
+
+Enabling clients to use Authorization Tokens
+============================================
+
+In order to use an untrusted client with an authorization token, a client must be configured to trust the server's CA,
+but must not be configured to use its certificates and keys. More concretely, a client's ``TLS_CA_FILE`` must include the server's root CA certificate,
+and a client must not be configured with its own ``TLS_CERTIFICATE_FILE`` or ``TLS_KEY_FILE``, neither programmatically nor by environment variable.
+Before performing a tenant data read or update, a client must set transaction option ``AUTHORIZATION_TOKEN`` with the token string as argument.
+It is the client's responsibility to keep the token up-to-date.
+
+Public Key Rotation
+===================
+
+Public key set automatically refreshes itself based on the file's latest content every ``PUBLIC_KEY_FILE_REFRESH_INTERVAL_SECONDS``.
+The in-memory set of public keys does not update unless the key file is a correct JWK set.
+
+Token Caching
+=============
+
+In a single-threaded runtime environment such as FoundationDB, it is important not to let the main thread be bogged down by computationally expensive operations,
+such as cryptographic signature verification. FoundationDB internally caches the tokens that are considered valid at the time of verification in a fixed-size LRU cache,
+whose size may be configured using ``TOKEN_CACHE_SIZE`` knob.
+
+.. note:: Token cache is independent of the active public key set. Once the token reaches the cache, it is valid until its expiration time,
+          regardless of any key rotation that takes place thereafter.

 Tenants
 #######
 
+.. _multi-tenancy:
+
 .. warning :: Tenants are currently experimental and are not recommended for use in production.
 
 FoundationDB provides a feature called tenants that allow you to configure one or more named transaction domains in your cluster. A transaction domain is a key-space in which a transaction is allowed to operate, and no tenant operations are allowed to use keys outside the tenant key-space. Tenants can be useful for managing separate, unrelated use-cases and preventing them from interfering with each other. They can also be helpful for defining safe boundaries when moving a subset of data between clusters.

 If the server was configured with trusted IP subnets, i.e. run with one or more ``--trusted-subnet-SUBNET_NAME`` followed by a CIDR block describing the subnet,
 then the client's IP as seen from the server must additionally belong to one of the subnets.

Subject: [PATCH 1028/1244] Introduce "default encryption domain" (#8139)

* Introduce "default encryption domain"

Description

In current FDB native encryption data at-rest implementation,
an entity getting encrypted (mutation, KV and/or file) is categorized
into one of following encryption domains:
1. Tenant domain, where, Encryption domain == Tenant boundaries
2. FDB system keyspace - FDB metadata encryption domain
3. FDB Encryption Header domain - used to generate digest for
plaintext EncryptionHeader.

The scheme doesn't support encryption if an entity can't be categorized
into any of above mentioned encryption domains, for instance, non-tenant
mutations are NOT supported.

Patch extend the encryption support for mutations for which corresponding
Tenant information can't be obtained (Key length shorter than TenantPrefix)
and/or mutations do not belong to any valid Tenant
(FDB management cluster data) by mapping such mutations to a
"default encryption domain".

TODO

CommitProxy driven TLog encryption implementation requires every transaction
mutation to contain 1 KV, not crossing Tenant-boundaries. Only exception to
this rule is ClearRange mutations. For now ClearRange mutations are mapped
to 'default encryption domain', in subsequent patch appropriate handling
for ClearRange mutations shall be proposed.

Testing

Subject: [PATCH 1036/1244] Disable zlib find_package, effectively disable gzip
 compression (#8179)

Description

find_package was used to find and link `zlib` library needed to enable
boost::gzip compression filter. However, the code adds dynamic linkage
of zlib shared object with generated binaries (fdbserver for instance).

For now disable the ZLIB find code to effectively disable GZIP compression
support.

Subject: [PATCH 1062/1244] Fix heap use after free (#8189)

Previously, we had Ref types outliving the arena's that owned them,
specifically encryptDomains in the getResolution actor. Refactor to use
Standalone's, which both fixes the memory error and makes this easier to
reason about.

Also fix a potential ODR violation.

From 74b152e550d786410614da224614a9fbe1cafdbb Mon Sep 17 00:00:00 2001

Subject: [PATCH 1072/1244] Removed two obsolete things:  explicit maxPriority
 argument from PriorityMultiLock as it is redundant after the launch limit
 refactor, and the redwood read concurrency lock which is no longer needed
 after the StorageServer priority refactor as it will control the concurrency
 of requests sent to the KVS.

Subject: [PATCH 1085/1244] Increase test coverage of TLS server-client
 combination (#8057)

Explore all combinations where the server and the client
each takes one of the following TLS/cert-chain configuration:
  No TLS, no chain, valid chain, expired chain, valid self-signed, expired self-signed

Negative cases are indirectly tested using timeouts:
  i.e. if it times out, it means it's not connecting

+ Fix TSAN data race error in original test
  (Calling FlowTransport::bind() with an active network thread running in background)
+ Properly redirect-and-capture subprocess stdout instead of just printing
  (CTest tends to truncate subprocess console outputs)

Subject: [PATCH 1096/1244] Fix Python binding's fdb_c lookup

All python documentations indicate you shouldn't put prefixes like 'lib' or
suffixes like '.so', '.dll', or '.dylib' in argument to ctypes.util.find_library(),
unlike ctypes.CDLL() which demands an exact file name.
I suppose this case hasn't been tested.

+Code Probes
+===========
+
+Code probes are a mechanism in FDB to prove that certain code-paths are being tested under the right conditions. They differ from code coverage in multiple ways (explained below).
+
+The general format of a code probe is:
+
+.. code-block:: C++
+
+   CODE_PROBE(<condition>, "Comment", [annotations...]);
+
+A simple example of a code probe could look as follows:
+
+.. code-block:: C++
+
+   CODE_PROBE(self->forceRecovery, "Resolver detects forced recovery", context::sim2);
+
+On a very high level, the above code will indicate that whenever this line is executed and ``self->forceRecovery`` is ``true``, we ran into some interesting case. In addition this probe is also annotated with ``context::sim2``. This indicates that we expect this code to be eventually hit in simulation.
+
+By default, FDB simply will write a trace-line when this code is hit and the condition is ``true``. If the code is never hit, the simulator will, at the end of the run, print the code probe but set the ``covered`` field to ``false``.
+
+We expect that ALL code probes will be hit in a nightly run. In the future we can potentially use this feature for other things (like instructing the simulator to do an extensive search starting when one of these probes is being hit).
+
+In addition to ``context`` annotations, users can also define and pass assertsions. For example:
+
+.. code-block:: C++
+
+   CODE_PROBE(condition, "Some comment", assert::simOnly);
+
+These will add an assertion to the code. In addition to that, the simulator will not print missed code probes that asserted that the probe won't be hit in simulation.
+
+Test Harness
+============
+
+TestHarness is our primary testing tool. It has multiple jobs:
+
+* *Running*: It can run a test in Joshua.
+* *Statictics*: It will chose a test to run based on previously spent CPU time for all tests. It does that by writing statistics about the test at the end of each run.
+* *Reporting*: After an ensemble has finished (or while it is running), ``TestHarness`` can be used to generate a report in ``xml`` or ``json``.
+
+Test Harness can be found in the FDB source repository under ``contrib/TestHarness2``. It has a weak dependency to `joshua <https://github.com/foundationDB/fdb-joshua>`_ (if Test Harness can find joshua it will report back about failed tests, otherwise it will just print out general statistics about the ensemble). Joshua will call Test Harness as follows:
+
+.. code-block:: shell
+
+   python3 -m test_harness.app -s ${JOSHUA_SEED} --old-binaries-path ${OLDBINDIR}
+
+Here the seed is a random number generated by joshua and ``OLDBINDIR`` is a directory path where the old fdb binaries can be found (this is needed for restart tests). If once wants to retry a test they can pass the previous joshua seed, a directory path that has *exactly* the same content as ``OLDBINARYDIR``, plus the reported statistics to the test harness app. This should then rerun the same code as before.
+
+In order to figure out what command line arguments ``test_harness.app`` (and ``test_harness.results``) accepts, one can check the contents of ``contrib/TestHarness2/test_harness/config.py``.
+
+Reporting
+---------
+
+After a joshua ensemble completed, ``test_harness.results`` can be used in order to get a report on the ensemble. This will include, by default, a list of all failed tests (similar to ``joshua tail --errors``, though in a more human readable file). For completed ensemble it will also print code probes that weren't hit often enough. An ensemble is considered to be successful if no simulation runs completed with an error AND all code probes have been hit sufficiently often.

Subject: [PATCH 1123/1244] sim: don't allow calls to killProcess or
 killInterface to kill protected processes.

killProcess_internal assumes that we've already checked and won't attempt to kill
a protected process. It's up to killProcess and killInterface, which are invoked
externally from simulated workloads, to enforce that constraint.

+tenant
+------
+
+The ``tenant`` command is used to view and manage the tenants in a cluster. The ``tenant`` command has the following subcommands:
+
+create
+^^^^^^
+
+``tenant create <NAME> [tenant_group=<TENANT_GROUP>]``
+
+Creates a new tenant in the cluster.
+
+``NAME`` - The desired name of the tenant. The name can be any byte string that does not begin with the ``\xff`` byte. 
+
+``TENANT_GROUP`` - The tenant group the tenant will be placed in.
+
+delete
+^^^^^^
+
+``tenant delete <NAME>``
+
+Deletes a tenant from the cluster. The tenant must be empty.
+
+``NAME`` - the name of the tenant to delete.
+
+list
+^^^^
+
+``tenant list [BEGIN] [END] [LIMIT]``
+
+Lists the tenants present in the cluster.
+
+``BEGIN`` - the first tenant to list. Defaults to the empty tenant name ``""``.
+
+``END`` - the exclusive end tenant to list. Defaults to ``\xff\xff``.
+
+``LIMIT`` - the number of tenants to list. Defaults to 100.
+
+get
+^^^
+
+``tenant get <NAME> [JSON]``
+
+Prints the metadata for a tenant.
+
+``NAME`` - the name of the tenant to print.
+
+``JSON`` - if specified, the output of the command will be printed in the form of a JSON string::
+
+    {
+        "tenant": {
+            "id": 0,
+            "prefix": {
+              "base64": "AAAAAAAAAAU=",

+            }
+        },
+        "type": "success"
+    }
+
+In the event of an error, the JSON output will include an error message::
+
+    {
+        "error": "...",
+        "type": "error"
+    }
+
+configure
+^^^^^^^^^
+
+``tenant configure <TENANT_NAME> <[unset] tenant_group[=GROUP_NAME]>``
+
+Changes the configuration of a tenant.
+
+``TENANT_NAME`` - the name of the tenant to reconfigure.
+
+The following tenant fields can be configured:
+
+``tenant_group`` - changes the tenant group a tenant is assigned to. If ``unset`` is specified, the tenant will be configured to not be in a group. Otherwise, ``GROUP_NAME`` must be specified to the new group that the tenant should be made a member of.
+
+rename
+^^^^^^
+
+``tenant rename <OLD_NAME> <NEW_NAME>``
+
+Changes the name of an existing tenant.
+
+``OLD_NAME`` - the name of the tenant being renamed.
+
+``NEW_NAME`` - the desired name of the tenant. This name must not already be in use.

Subject: [PATCH 1141/1244] Limit BUILD_AWS_BACKUP to x86_64 for now

With aarch64, in the current docker image, linking curl statically doesn't work yet.

This is the diagnostic:

```
fdbclient/awssdk-build/curl/lib/strerror.c:32:6: error: #error "strerror_r MUST be either POSIX, glibc or vxworks-style"
2022-09-22 16:05:30   #    error "strerror_r MUST be either POSIX, glibc or vxworks-style"
2022-09-22 16:05:30        ^~~~~
```

The root cause is that curl's cmake feature detection logic gets
confused since it can't build binaries that execute successfully with
the link flags it wants:

```
$ cc test.c -lssl
$ ./a.out
./a.out: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
```

+tenantgroup
+-----------
+
+The ``tenantgroup`` command is used to view details about the tenant groups in a cluster. The ``tenantgroup`` command has the following subcommands:
+
+list
+^^^^
+
+``tenantgroup list [BEGIN] [END] [LIMIT]``
+
+Lists the tenant groups present in the cluster.
+
+``BEGIN`` - the first tenant group to list. Defaults to the empty tenant group name ``""``.
+
+``END`` - the exclusive end tenant group to list. Defaults to ``\xff\xff``.
+
+``LIMIT`` - the number of tenant groups to list. Defaults to 100.
+
+get
+^^^
+
+``tenantgroup get <NAME> [JSON]``
+
+Prints the metadata for a tenant group.
+
+``NAME`` - the name of the tenant group to print.
+
+``JSON`` - if specified, the output of the command will be printed in the form of a JSON string::
+
+    {
+        "tenant_group": {
+            "assigned_cluster": "cluster1",
+        },
+        "type": "success"

Subject: [PATCH 1153/1244] Enable ZSTD compression support (#8014)

* Enable ZSTD compression filter

Description

  diff-4: Randomize Knob Compression filter selection
  diff-3: Minor refactoring
  diff-2: Limit ZSTD availability to CLANG compiler
  diff-1: Add ZSTD compression option to BlobGranule tests

Major changes includes:
1. Update FDB CMake to download, install and build Boost with
ZSTD compatibility
2. Update CompressionUtils to enable boost::iostreams::zstd
compression filter

Subject: [PATCH 1165/1244] Change crashAndDie to abort instead of segv (#7827)

* Change crashAndDie to abort instead of segv

This way we still terminate early when `--crash` is set, but folks
inspecting error reports don't get mislead and confuse assertion
failures with genuine memory errors.

* Add SIGABRT to crash handler

 When the `GLOBAL_TAG_THROTTLING` knob is enabled, the ratekeeper will use the [transaction tagging feature](https://apple.github.io/foundationdb/transaction-tagging.html) to throttle tags according to the global tag throttling algorithm. This page describes the implementation of this algorithm.
 
 ### Tag Quotas
-The global tag throttler bases throttling decisions on "quotas" provided by clients through the tag quota API. Each tag quota has four different components:
+The global tag throttler bases throttling decisions on "quotas" provided by clients through the tag quota API. Each tag quota has two components:

+Internally, the units for these quotas are "page costs", computed as follows. The "page cost" of a read operation is computed as:
 
 ```
-readCost = bytesRead / SERVER_KNOBS->READ_COST_BYTE_FACTOR + 1;

 ```
 
 Here `bytesWritten` includes cleared bytes. The size of range clears is estimated at commit time.
 
 ### Tuple Layer
-Tag quotas are stored inside of the system keyspace (with prefix `\xff/tagQuota/`). They are stored using the tuple layer, in a tuple of form: `(reservedReadQuota, totalReadQuota, reservedWriteQuota, totalWriteQuota)`. There is currently no custom code in the bindings for manipulating these system keys. However, in any language for which bindings are available, it is possible to use the tuple layer to manipulate tag quotas.

Subject: [PATCH 1173/1244] tuple: user defined type support (#8300)

* tuple: add support for usertype as last part of tuple

The expectation is user defined types come at the end as there is no
delimiter standard. In that case, if we encounter a user defined type,
we append it to the end of the tuple and allow users to transform that
type by parsing raw string returned.

* blob: use Tuple::unpackUserType() for key alignment

We want blob granule key alignment to be able to understand user data
types. This upgrades support and allows user data types to be the last
key in a blob granule and for us to be able to parse that properly.

Subject: [PATCH 1174/1244] Fix RocksDB link issue (#8296)

* Fix the RocksDB compile issue with clang

By default, RocksDB is using its own compile/link flags, no matter how
FDB flags are. This led to the issue that if FDB decides to use
clang/ldd/libc++, RocksDB will pick up the compiler/linker but still use
libstdc++, which is incompatible to libc++, causing Symobl Missing error
during the link stage.

With this patch, if FDB uses libc++, then the information is stored in
CMAKE_CXX_FLAGS and being forwarded to RocksDB. RocksDB will then use
libc++ and compatible with FDB.

* fixup! update the indentation

-// Both Range and Log formats are designed to be readable starting at any 1MB boundary
+// Both Range and Log formats are designed to be readable starting at any BACKUP_RANGEFILE_BLOCK_SIZE boundary
+// so they can be read in parallel.
+//
+// Writer instances must be kept alive while any member actors are in progress.
+//
+// EncryptedRangeFileWriter must be used as follows:
+//   1 - writeKey(key) the queried key range begin
+//   2 - writeKV(k, v) each kv pair to restore
+//   3 - writeKey(key) the queried key range end
+//   4 - finish()
+//
+// EncryptedRangeFileWriter will insert the required padding, header, and extra
+// end/begin keys around the 1MB boundaries as needed.
+//
+// Example:
+//   The range a-z is queries and returns c-j which covers 3 blocks across 2 tenants.
+//   The client code writes keys in this sequence:
+//             t1a t1c t1d t1e t1f t1g t2h t2i t2j t2z
+//
+//   H = header   P = padding   a...z = keys  v = value | = block boundary
+//
+//   Encoded file:  H t1a t1cv t1dv t1ev P | H t1e t1ev t1fv t1gv t2 P | H t2 t2hv t2iv t2jv t2z
+//   Decoded in blocks yields:
+//           Block 1: range [t1a, t1e) with kv pairs t1cv, t1dv
+//           Block 2: range [t1e, t2) with kv pairs t1ev, t1fv, t1gv
+//           Block 3: range [t2, t2z) with kv pairs t2hv, t2iv, t2jv
+//
+//   NOTE: All blocks except for the final block will have one last
+//   value which will not be used.  This isn't actually a waste since
+//   if the next KV pair wouldn't fit within the block after the value
+//   then the space after the final key to the next 1MB boundary would
+//   just be padding anyway.
+//
+//   NOTE: For the EncryptedRangeFileWriter blocks will be split either on the BACKUP_RANGEFILE_BLOCK_SIZE boundary or
+//   when a new tenant id is encountered. If a block is split for crossing tenant boundaries then the last key will be
+//   truncated to just the tenant prefix and the value will be empty (to avoid having sensitive data of one tenant be

Subject: [PATCH 1222/1244] Enable encryption authentication configurability
 (#8312)

* Enable encryption authentication configurability

Description

 diff-1: Remove memcpy due to auth-token computation
         Address review comments

Patch proposes major changes:
1. Enable FDB to choose encryption authentication as a configurable
parameter. Fix issues choosing ENCRYPT_HEADER_AUTH_TOKEN_NONE mode.
2. Introduce AES_CMAC as supported encryption authentication scheme.

Patch allows cluster to govern: if encryption authentication needs to
enabled, if yes, then choose from two supported schemes:
1. HMAC_SHA_256
2. AES_256_CMAC

Testing

Subject: [PATCH 1229/1244] Init TLogPersistent storage for a sharedTLog
 (#8363)

* Init TLogPersistent storage for a sharedTLog

Description

  diff-1: Address review comments

Patch udpates the code to intialize TLogPersistent storage for a
shared TLog independent of intializing persistentState for a
versioned Tlog data. Appraoch allows initializing Tlog persistent
storage as well as writing 'persistFormat' key for a shared TLog
earlier in the TLog creation lifecycle.

Subject: [PATCH 1231/1244] Update TenantEntryCache workload refresh to handle
 fault injection (#8369)

* Update TenantEntryCache workload refresh to handle fault injection

Description

 diff-1: Add trace event to log wait

Patch update TenantEntryCache::testCacheRefresh to better handle fault
injection causing longer cluster recovery/availability delays. The
test is modified to loop for a threshold time waiting for next round
of tenantCache refresh cycle to happen. Otherwise throws 'timed_out'
error.

Testing

Subject: [PATCH 1243/1244] Split Redwood page by tenant boundary (#7979)

Redwood encrypt with page granularity. To do per-tenant encryption (i.e. each tenant are encrypted with different set of cipher keys), we need to split Redwood pages by tenant boundary. Moreover, it also needs to handle different tenant modes:
* tenantMode = disabled: do not split page by tenant, all data encrypt using default encryption domain.
* tenantMode = required: look at the prefix of the keys and split by tenant accordingly, and encrypt in tenant specific encryption domain accordingly.
* tenantMode = optional: some key ranges may not map to a tenant. In additional to looking at the key prefix, the key provider also query the tenant prefix index. For prefixes not found in the tenant prefix index, corresponding key should be encrypted using the default encryption domain.

The change also enforce data for each tenant forms a subtree, and key of the link to the subtree is exactly the tenant prefix.

This PR is building on top of #8172 and use the IPageEncryptionKeyProvider interface added there. Changes:
* In `writePages` and `splitPages`, query the key provider to split page accordingly.
* In `commitSubtree`, when doing in-place update (to both of leaf or internal page), check if the entry being insert belong to the same encryption domain as existing data of the page. If not, fallback to full page rebuild, where `writePages` will handle the page split.
* When updating the root, check if it is encrypted using non-default (i.e. tenant specific) domain. If so, add a redundant root node which will be encrypted with default encryption domain.

Tested with 100K run of `Lredwood/correctness/btree` unit test, where it uses `RandomEncryptionKeyProvider`, which is updated to support and generate random encryption domain with 4 byte domain prefixes.
