The workers in different processes can still access the global variables, which makes one worker overwrite another work's global variable value. To solve this problem, which happens in other FDB code as well, we allocate the global variable in a heap and pass the pointers across functions, as what DataDistribution.actor does. The other approach is to create two code path: one for real mode and the other for simulator, as the g_simulator does to create the process context for each simulated process --- fdbclient/BackupContainer.h | 19 +- fdbserver/Restore.actor.cpp | 624 ++++++++++++++++++++++++--------- fdbserver/RestoreInterface.h | 15 +- fdbserver/TLogServer.actor.cpp | 1 + 4 files changed, 480 insertions(+), 179 deletions(-) diff --git a/fdbclient/BackupContainer.h b/fdbclient/BackupContainer.h index 1fea16c6bb..5b47da048d 100644 --- a/fdbclient/BackupContainer.h +++ b/fdbclient/BackupContainer.h @@ -144,16 +144,15 @@ struct RestorableFileSet { std::vector logs; std::vector ranges; KeyspaceSnapshotFile snapshot; - //RestorableFileSet(Void) {} //work around compilation - /* - - RestorableFileSet(RestorableFileSet &fileSet) { - targetVersion = fileSet.targetVersion; - logs = fileSet.logs; - ranges = fileSet.ranges; - snapshot = fileSet.snapshot; - } - */ +// RestorableFileSet(Void) {} //work around compilation +// +// RestorableFileSet(RestorableFileSet &fileSet) { +// targetVersion = fileSet.targetVersion; +// logs = fileSet.logs; +// ranges = fileSet.ranges; +// snapshot = fileSet.snapshot; +// } +// }; /* IBackupContainer is an interface to a set of backup data, which contains diff --git a/fdbserver/Restore.actor.cpp b/fdbserver/Restore.actor.cpp index 5b76766efd..b19a16296a 100644 --- a/fdbserver/Restore.actor.cpp +++ b/fdbserver/Restore.actor.cpp @@ -55,11 +55,72 @@ std::map, uint32_t> mutationPartMap; //Record the most rec //Standalone> mOps; std::vector mOps; + //---- Declare status structure which records the progress and status of each worker in each role +std::map workers_interface; // UID is worker's node id, RestoreCommandInterface is worker's communication interface +void printGlobalNodeStatus(); RestoreNodeStatus localNodeStatus; //Each worker node (process) has one such variable. +ApplierState applierState; // each applier should keep its state -std::vector globalNodeStatus; // status of all notes, stored in master node +std::vector globalNodeStatus; // status of all notes, excluding master node, stored in master node // May change to map, like servers_info +std::map, UID> range2Applier; // KeyRef is the inclusive lower bound of the key range the applier (UID) is responisible for + +//Print out the works_interface info +void printWorkersInterface(){ + printf("[INFO] workers_interface info: num of workers:%d\n", workers_interface.size()); + int index = 0; + for (auto &interf : workers_interface) { + printf("\t[INFO][Worker %d] NodeID:%s, Interface.id():%s\n", index, + interf.first.toString().c_str(), interf.second.id().toString().c_str()); + } +} + + +// Return in the system +std::pair getNumLoaderAndApplier() { + int numLoaders = 0; + int numAppliers = 0; + for (int i = 0; i < globalNodeStatus.size(); ++i) { + if (globalNodeStatus[i].role == RestoreRole::Loader) { + numLoaders++; + } else if (globalNodeStatus[i].role == RestoreRole::Applier) { + numAppliers++; + } + } + + if ( numLoaders + numAppliers != globalNodeStatus.size() ) { + printf("[ERROR] Number of workers does not add up! numLoaders:%d, numApplier:%d, totalProcess:%d\n", + numLoaders, numAppliers, globalNodeStatus.size()); + } + + return std::make_pair(numLoaders, numAppliers); +} + +std::vector getApplierIDs() { + std::vector applierIDs; + for (int i = 0; i < globalNodeStatus.size(); ++i) { + if (globalNodeStatus[i].role == RestoreRole::Applier) { + applierIDs.push_back(globalNodeStatus[i].nodeID); + } + } + + // Check if there exist duplicate applier IDs, which should never occur + std::sort(applierIDs.begin(), applierIDs.end()); + bool unique = true; + for (int i = 1; i < applierIDs.size(); ++i) { + if (applierIDs[i-1] == applierIDs[i]) { + unique = false; + break; + } + } + if (!unique) { + printf("[ERROR] Applier IDs are not unique!

To solve this problem, we use inProgressFlag to record the phase a worker is currently working on: each set bit in inProgressFlag indicates a in-progress phase. When a worker invoke an actor for a phase, It first check the inProgressFlag if the worker is currently working in the phase; if yes, the worker's actor for the same phase will wait; Once the actor is the only one working in the phase, it sets the bit in inProgressFlag. When the actor finishes the phase, it clears the bit. This solve the race condition, although it does not perfectly solve it. To solve the race condition, i.e., avoiding the rare race between machine instructions, we need to use lock (or mutex) to ensure only one can access the flag. This commit also enclose the unlockDB logic into a try-catch loop. Otherwise, the unlockDB error will fail the correctness test. --- fdbserver/Restore.actor.cpp | 180 +++++++++++++++++++++++++----------- 1 file changed, 128 insertions(+), 52 deletions(-) diff --git a/fdbserver/Restore.actor.cpp b/fdbserver/Restore.actor.cpp index 6e2f8155c8..538e82002b 100644 --- a/fdbserver/Restore.actor.cpp +++ b/fdbserver/Restore.actor.cpp @@ -739,10 +739,29 @@ struct RestoreData : NonCopyable, public ReferenceCounted { std::vector> keyRangeLowerBounds; bool inProgressApplyToDB = false; + uint32_t inProgressFlag = 0; // Command id to record the progress CMDUID cmdID; + void setInProgressFlag(RestoreCommandEnum phaseEnum) { + int phase = (int) phaseEnum; + ASSERT(phase < 32); + inProgressFlag |= (1UL << phase); + } + + void clearInProgressFlag(RestoreCommandEnum phaseEnum) { + int phase = (int) phaseEnum; + ASSERT(phase < 32); + inProgressFlag &= ~(1UL << phase); + } + + bool isInProgress(RestoreCommandEnum phaseEnum) { + int phase = (int) phaseEnum; + ASSERT(phase < 32); + return (inProgressFlag & (1UL << phase)); + } + RestoreRole getRole() { return localNodeStatus.role; } @@ -2927,6 +2946,42 @@ ACTOR Future initializeVersionBatch(Reference rd, int batchIn return Void(); } +ACTOR Future finishRestore(Reference rd) { + // Make restore workers quit + state std::vector workersIDs = getWorkerIDs(rd); + state std::vector> cmdReplies; + state int tryNum = 0; // TODO: Change it to a more robust way which uses DB to check which process has already been destroyed. + loop { + try { + tryNum++; + if (tryNum >= 3) { + break; + } + cmdReplies.clear(); + rd->cmdID.initPhase(RestoreCommandEnum::Finish_Restore); + for (auto &nodeID : workersIDs) { + rd->cmdID.nextCmd(); + ASSERT( rd->workers_interface.find(nodeID) != rd->workers_interface.end() ); + RestoreInterface &interf = rd->workers_interface[nodeID]; + cmdReplies.push_back(interf.finishRestore.getReply(RestoreSimpleRequest(rd->cmdID))); + } + + if (!cmdReplies.empty()) { + std::vector reps = wait( timeoutError( getAll(cmdReplies), FastRestore_Failure_Timeout / 100 ) ); + //std::vector reps = wait( getAll(cmdReplies) ); + cmdReplies.clear(); + } + printf("All restore workers have quited\n"); + + break; + } catch(Error &e) { + printf("[ERROR] At sending finishRestore request. error code:%d message:%s.

From a08a6776f5bba6bcc15c72202fa1fd1ce2aafb47 Mon Sep 17 00:00:00 2001 From: Meng Xu Date: Thu, 9 May 2019 20:55:44 -0700 Subject: [PATCH 0157/2587] FastRestore: Refactor to smaller components The current code uses one restore interface to handle the work for all restore roles, i.e., master, loader and applier. This makes it harder to review or maintain or scale. This commit split the restore into multiple roles by mimicing FDB transaction system: 1) It uses a RestoreWorker as the process to host restore roles; This commit assumes one restore role per RestoreWorker; but it should be easy to extend to support multiple roles per RestoreWorker; 2) It creates 3 restore roles: RestoreMaster: Coordinate the restore process and send commands to the other two roles; RestoreLoader: Parse backup files to mutations and send mutations to appliers; RestoreApplier: Sort received mutations and apply them to DB in order. Compilable version.

The cmdid is used to achieve exact once delivery even when network can deliver a request twice. This is under assumption that cmdid is unique for each request! However, this assumption may not hold for the phase Loader_Send_Mutations_To_Applier, when loaders send parsed mutations to appliers: 1) When the same loader loads multiple files, we reset the cmdid for the phase; 2) When different loaders load files, each loader's cmdid starts from 0 for the phase. Both situations can break the assumption, which causes appliers to miss some mutations to apply.

If the ack is lost, it will not be resent. This commit also removes some unneeded code.

Defaults to ``true``. * ``disable_lifecycle_logging``: If ``true``, ``fdbmonitor`` will not write log events when processes start or terminate. Defaults to ``false``. +The ``[general]`` section also contains some parameters to control how processes are restarted when they die. ``fdbmonitor`` uses backoff logic to prevent a process that dies repeatedly from cycling too quickly, and it also introduces up to +/-10% random jitter into the delay to avoid multiple processes all restarting simultaneously. ``fdbmonitor`` tracks separate backoff state for each process, so the restarting of one process will have no effect on the backoff behavior of another. + +* ``restart_delay``: The maximum number of seconds (subject to jitter) that fdbmonitor will delay before restarting a failed process. +* ``initial_restart_delay``: The number of seconds ``fdbmonitor`` waits to restart a process the first time it dies. Defaults to 0 (i.e. the process gets restarted immediately). +* ``restart_backoff``: Controls how quickly ``fdbmonitor`` backs off when a process dies repeatedly. The previous delay (or 1, if the previous delay is 0) is multiplied by ``restart_backoff`` to get the next delay, maxing out at the value of ``restart_delay``. Defaults to the value of ``restart_delay``, meaning that the second and subsequent failures will all delay ``restart_delay`` between restarts. +* ``restart_delay_reset_interval``: The number of seconds a process must be running before resetting the backoff back to the value of ``initial_restart_delay``. Defaults to the value of ``restart_delay``. + +As an example, let's say the following parameters have been set: + +.. code-block:: ini + + restart_delay = 60 + initial_restart_delay = 0 + restart_backoff = 2.0 + restart_delay_reset_interval = 180 + +The progression of delays for a process that fails repeatedly would be ``0, 2, 4, 8, 16, 32, 60, 60, ...``, each subject to a 10% random jitter. After the process stays alive for 180 seconds, the backoff would reset and the next failure would restart the process immediately. + +Using the default parameters, a process will restart immediately if it fails and then delay ``restart_delay`` seconds if it fails again within ``restart_delay`` seconds. + .. _foundationdb-conf-fdbserver: ``[fdbserver]`` section From 85ba904e2c009da65a4a5a2847ffc302dd0837e0 Mon Sep 17 00:00:00 2001 From: Meng Xu Date: Fri, 16 Aug 2019 16:11:28 -0700 Subject: [PATCH 0494/2587] StorageEngineSwitch:Stop removeWrongStoreType actor if no SS has wrong storeType --- fdbserver/DataDistribution.actor.cpp | 37 +++++++++------------------- fdbserver/Knobs.cpp | 5 ++-- fdbserver/Knobs.h | 8 +++--- 3 files changed, 16 insertions(+), 34 deletions(-) diff --git a/fdbserver/DataDistribution.actor.cpp b/fdbserver/DataDistribution.actor.cpp index 61482e4f52..7b16177d44 100644 --- a/fdbserver/DataDistribution.actor.cpp +++ b/fdbserver/DataDistribution.actor.cpp @@ -715,7 +715,6 @@ struct DDTeamCollection : ReferenceCounted { } ACTOR static Future interruptableBuildTeams( DDTeamCollection* self ) { - TraceEvent("DDInterruptableBuildTeamsStart", self->distributorId); if(!self->addSubsetComplete.isSet()) { wait( addSubsetOfEmergencyTeams(self) ); self->addSubsetComplete.send(Void()); @@ -732,7 +731,6 @@ struct DDTeamCollection : ReferenceCounted { } ACTOR static Future checkBuildTeams( DDTeamCollection* self ) { - TraceEvent("DDCheckBuildTeamsStart", self->distributorId); wait( self->checkTeamDelay ); while( !self->teamBuilder.isReady() ) wait( self->teamBuilder ); @@ -758,7 +756,6 @@ struct DDTeamCollection : ReferenceCounted { // shardsAffectedByTeamFailure or we could be dropping a shard on the floor (since team // tracking is "edge triggered") // SOMEDAY: Account for capacity, load (when shardMetrics load is high) - // Q: How do we enforce the above statement? // self->teams.size() can be 0 under the ConfigureTest.txt test when we change configurations // The situation happens rarely.

Also fixed header page size handling which would write unusable backup headers when using >4k pages. --- fdbserver/VersionedBTree.actor.cpp | 125 +++++++++++++++++++---------- 1 file changed, 82 insertions(+), 43 deletions(-) diff --git a/fdbserver/VersionedBTree.actor.cpp b/fdbserver/VersionedBTree.actor.cpp index f8d6efdd1b..914882d176 100644 --- a/fdbserver/VersionedBTree.actor.cpp +++ b/fdbserver/VersionedBTree.actor.cpp @@ -63,7 +63,7 @@ public: int64_t numPages; int64_t numEntries; std::string toString() const { - return format("head: %u:%d tail: %u:%d numPages: %" PRId64 " numEntries: %" PRId64 "\n", headPageID, (int)headIndex, tailPageID, numPages, numEntries); + return format("head: %u:%d tail: %u numPages: %" PRId64 " numEntries: %" PRId64 "\n", headPageID, (int)headIndex, tailPageID, numPages, numEntries); } }; #pragma pack(pop) @@ -90,7 +90,7 @@ public: // Point cursor to a page which has never been written before, allocate // a page buffer and initialize it void initWrite(FIFOQueue *q, LogicalPageID newPageID) { - debug_printf("New queue cursor at page id=%u write=%d\n", newPageID, write); + debug_printf("FIFOQueue(%s): New write queue cursor at page id=%u\n", q->name.c_str(), newPageID); queue = q; pageID = newPageID; initNewPageBuffer(); @@ -98,7 +98,7 @@ public: // Point cursor to a page to read from.

When switching between spill_type or log_version, a new instance of a SharedTLog is created in the transaction log processes. If this is done in a saturated database, then doubling the amount of memory to hold mutations in memory can cause TLogs to be uncomfortably close to the 8GB OOM limit. Instead, we now thread which UID of a SharedTLog is active, and the other TLog spill out the majority of their mutations. --- fdbserver/OldTLogServer_6_0.actor.cpp | 26 ++++++++++++++++--- fdbserver/OldTLogServer_6_2.actor.cpp | 26 ++++++++++++++++--- fdbserver/TLogServer.actor.cpp | 26 ++++++++++++++++--- fdbserver/WorkerInterface.actor.h | 10 +++++--- fdbserver/worker.actor.cpp | 37 +++++++++++++++++++-------- 5 files changed, 99 insertions(+), 26 deletions(-) diff --git a/fdbserver/OldTLogServer_6_0.actor.cpp b/fdbserver/OldTLogServer_6_0.actor.cpp index 3c05ecb8e0..ab9e34876f 100644 --- a/fdbserver/OldTLogServer_6_0.actor.cpp +++ b/fdbserver/OldTLogServer_6_0.actor.cpp @@ -262,6 +262,7 @@ struct TLogData : NonCopyable { int64_t instanceID;

Many bug fixes involving scheduled page freeing, page list queue flushing, and expiring old snapshots (this was mostly written but not used yet). Rewrote most of FIFOQueue (again) to more cleanly handle queue cyclical dependencies caused by having queues that use a pager which in tern uses the same queues for managing page freeing and allocation. Many debug output improvements, including making BTreePageIDs and LogicalPageIDs stringify the same way everywhere to make following a PageID easier. --- fdbserver/IPager.h | 2 +- fdbserver/VersionedBTree.actor.cpp | 1090 ++++++++++++++-------------- 2 files changed, 560 insertions(+), 532 deletions(-) diff --git a/fdbserver/IPager.h b/fdbserver/IPager.h index e2805770f9..508c90cf9b 100644 --- a/fdbserver/IPager.h +++ b/fdbserver/IPager.h @@ -205,7 +205,7 @@ public: virtual void setMetaKey(KeyRef metaKey) = 0; // Sets the next commit version - virtual void setVersion(Version v) = 0; + virtual void setCommitVersion(Version v) = 0; virtual StorageBytes getStorageBytes() = 0; diff --git a/fdbserver/VersionedBTree.actor.cpp b/fdbserver/VersionedBTree.actor.cpp index 2047ccd9e4..e37c44f436 100644 --- a/fdbserver/VersionedBTree.actor.cpp +++ b/fdbserver/VersionedBTree.actor.cpp @@ -50,7 +50,10 @@ std::string toString(const T &o) { } std::string toString(LogicalPageID id) { - return format("%" PRId64, id); + if(id == invalidLogicalPageID) { + return "LogicalPageID{invalid}"; + } + return format("LogicalPageID{%" PRId64 "}", id); } template @@ -87,23 +90,35 @@ std::string toString(const VectorRef &v) { return toString(v.begin(), v.end()); } +template +std::string toString(const Optional &o) { + if(o.present()) { + return toString(o.get()); + } + return ""; +} + // A FIFO queue of T stored as a linked list of pages. -// Operations are pop(), pushBack(), and pushFront(), and flush(). -// Flush() will ensure all queue pages are written to the pager. +// Main operations are pop(), pushBack(), pushFront(), and flush(). +// +// flush() will ensure all queue pages are written to the pager and move the unflushed +// pushFront()'d records onto the front of the queue, in FIFO order. +// // pop() will only return records that have been flushed, and pops // from the front of the queue. // -// Each page contains some number of T items and a link to the next page. +// Each page contains some number of T items and a link to the next page and starting position on that page. // When the queue is flushed, the last page in the chain is ended and linked to a newly allocated // but not-yet-written-to pageID, which future writes after the flush will write to. // Items pushed onto the front of the queue are written to a separate linked list until flushed, // at which point that list becomes the new front of the queue. // -// Committing changes to a queue involves flushing the queue, calling fsync, and then -// writing the QueueState which flush() returns somewhere and making it durable. -// -// The write pattern is designed such that no written/updated yet not fsync'd page is ever -// expected to be valid. +// The write pattern is designed such that no page is ever expected to be valid after +// being written to or updated but not fsync'd.

When switching between spill_type or log_version, a new instance of a SharedTLog is created in the transaction log processes. If this is done in a saturated database, then doubling the amount of memory to hold mutations in memory can cause TLogs to be uncomfortably close to the 8GB OOM limit. Instead, we now thread which UID of a SharedTLog is active, and the other TLog spill out the majority of their mutations.

Removed old prototype code (PrefixTree, IndirectShadowPager, MemoryPager) as some interface changes are incompatible and they are no longer worth maintaining. --- fdbserver/CMakeLists.txt | 4 - fdbserver/DeltaTree.h | 78 +- fdbserver/IPager.h | 76 +- fdbserver/IVersionedStore.h | 10 +- fdbserver/IndirectShadowPager.actor.cpp | 960 --------------------- fdbserver/IndirectShadowPager.h | 215 ----- fdbserver/MemoryPager.actor.cpp | 456 ---------- fdbserver/MemoryPager.h | 29 - fdbserver/PrefixTree.h | 1049 ----------------------- fdbserver/VersionedBTree.actor.cpp | 526 ++++++++---- fdbserver/fdbserver.vcxproj | 4 - fdbserver/fdbserver.vcxproj.filters | 4 - 12 files changed, 432 insertions(+), 2979 deletions(-) delete mode 100644 fdbserver/IndirectShadowPager.actor.cpp delete mode 100644 fdbserver/IndirectShadowPager.h delete mode 100644 fdbserver/MemoryPager.actor.cpp delete mode 100644 fdbserver/MemoryPager.h delete mode 100644 fdbserver/PrefixTree.h diff --git a/fdbserver/CMakeLists.txt b/fdbserver/CMakeLists.txt index 9301a3245b..d4c5e5f226 100644 --- a/fdbserver/CMakeLists.txt +++ b/fdbserver/CMakeLists.txt @@ -24,8 +24,6 @@ set(FDBSERVER_SRCS IKeyValueStore.h IPager.h IVersionedStore.h - IndirectShadowPager.actor.cpp - IndirectShadowPager.h KeyValueStoreCompressTestData.actor.cpp KeyValueStoreMemory.actor.cpp KeyValueStoreSQLite.actor.cpp @@ -45,8 +43,6 @@ set(FDBSERVER_SRCS MasterInterface.h MasterProxyServer.actor.cpp masterserver.actor.cpp - MemoryPager.actor.cpp - MemoryPager.h MoveKeys.actor.cpp MoveKeys.actor.h networktest.actor.cpp diff --git a/fdbserver/DeltaTree.h b/fdbserver/DeltaTree.h index ce584f76f2..b1eb53dfff 100644 --- a/fdbserver/DeltaTree.h +++ b/fdbserver/DeltaTree.h @@ -20,13 +20,89 @@ #pragma once -#include "fdbserver/PrefixTree.h" #include "flow/flow.h" #include "flow/Arena.h" #include "fdbclient/FDBTypes.h" #include "fdbserver/Knobs.h" #include +typedef uint64_t Word; +static inline int commonPrefixLength(uint8_t const* ap, uint8_t const* bp, int cl) { + int i = 0; + const int wordEnd = cl - sizeof(Word) + 1; + + for(; i < wordEnd; i += sizeof(Word)) { + Word a = *(Word *)ap; + Word b = *(Word *)bp; + if(a != b) { + return i + ctzll(a ^ b) / 8; + } + ap += sizeof(Word); + bp += sizeof(Word); + } + + for (; i < cl; i++) { + if (*ap != *bp) { + return i; + } + ++ap; + ++bp; + } + return cl; +} + +static int commonPrefixLength(StringRef a, StringRef b) { + return commonPrefixLength(a.begin(), b.begin(), std::min(a.size(), b.size())); +} + +// This appears to be the fastest version +static int lessOrEqualPowerOfTwo(int n) { + int p; + for (p = 1; p+p <= n; p+=p); + return p; +} + +/* +static int _lessOrEqualPowerOfTwo(uint32_t n) { + if(n == 0) + return n; + int trailing = __builtin_ctz(n); + int leading = __builtin_clz(n); + if(trailing + leading == ((sizeof(n) * 8) - 1)) + return n; + return 1 << ( (sizeof(n) * 8) - leading - 1); +} + +static int __lessOrEqualPowerOfTwo(unsigned int n) { + int p = 1; + for(; p <= n; p <<= 1); + return p >> 1; +} +*/ + +static int perfectSubtreeSplitPoint(int subtree_size) { + // return the inorder index of the root node in a subtree of the given size + // consistent with the resulting binary search tree being "perfect" (having minimal height + // and all missing nodes as far right as possible). + // There has to be a simpler way to do this. + int s = lessOrEqualPowerOfTwo((subtree_size - 1) / 2 + 1) - 1; + return std::min(s * 2 + 1, subtree_size - s - 1); +} + +static int perfectSubtreeSplitPointCached(int subtree_size) { + static uint16_t *points = nullptr; + static const int max = 500; + if(points == nullptr) { + points = new uint16_t[max]; + for(int i = 0; i < max; ++i) + points[i] = perfectSubtreeSplitPoint(i); + } + + if(subtree_size < max) + return points[subtree_size]; + return perfectSubtreeSplitPoint(subtree_size); +} + // Delta Tree is a memory mappable binary tree of T objects such that each node's item is // stored as a Delta which can reproduce the node's T item given the node's greatest // lesser ancestor and the node's least greater ancestor. diff --git a/fdbserver/IPager.h b/fdbserver/IPager.h index dc58461e47..8f79d9c57f 100644 --- a/fdbserver/IPager.h +++ b/fdbserver/IPager.h @@ -53,8 +53,9 @@ #define VALGRIND_MAKE_MEM_DEFINED(x, y) #endif -typedef uint32_t LogicalPageID; // uint64_t?

This document discusses the internals of data distribution (DD) from three perspectives: components that are the data structure of DD; operations that are the actors changing the states of DD; and mechanisms that realize functionalities of DD. + +## Components + +**Storage server (struct TCServerInfo):** DD creates a TCServerInfo object for each storage server (SS). The TCServerInfo includes: (i) the SS’ locality, which includes the processID that is unique to ip:port, the zoneId that specifies which rack the SS is on, and the dcId that specifies which DC the SS is in; (ii) the server’s teams, which will be discussed in the following paragraph; (iii) the tracker that monitor the status of the server; and (iv) extra information related to the server’s interface and preference. A server is healthy if its storage engine on the process is the same with the configured storage engine, and it is marked as desired by DD. + +**Machine (struct TCMachineInfo)**: A machine in FDB is considered as a rack, because a typical FDB cluster will only use one physical host from each rack in the datacenter to reduce the impact of regular rack-maintenance events on the cluster. All servers on the same rack belong to the same machine. A machine is healthy if there exists a healthy server on the machine. + +**Server team (struct TCTeamInfo)**: A server team is a group of k servers that host the same key ranges, where k is the replication factor that is usually three. A server team is healthy if every server in the team is healthy and those servers’ localities satisfies the replication requirement. Servers are grouped into server teams to reduce the possibility of data unavailability events at the event of k server failures. + +**Machine team (struct TCMachineTeamInfo)**: A machine team is a group of k machines, where k is the replication factor. Each server team must be on a machine team, meaning that each server in the server team is on a machine in the machine team and that no two servers are on the same machine. Similar to the purpose of server teams, machine teams are used to reduce the possibility of data unavailability events at the event of k _machine_ failures. A machine team is healthy if every machine on the team is healthy and machines’ localities satisfy the replication policy. + +**TeamCollection**: It has a global view of all servers and server teams, machines and machine teams. With the information, it creates server teams and machine teams. It also maintains the configuration setting for DD, which is used to create teams and decide which type of storage servers to recruit. + +**Shard (struct DDShardInfo)**: A shard is a key range. A shard is maintained by a server team. A server team is responsible for lots of shards. Each shard has similar amount of data. When a shard has too much data or has too much write traffic, it will be split into multiple shards and redistributed to server teams. Likewise, when a shard has too small data, it can be merged with its neighbors. + +**RelocateShard (struct RelocateShard)**: A RelocateShard records the key range that need to be move among servers and the data movement’s priority. DD always move shards with higher priorities first. + +**Data distribution queue (struct DDQueueData)**: It receives shards to be relocated (i.e., RelocateShards), decides which shard should be moved to which server team, prioritizes the data movement based on relocate shard’s priority, and control the progress of data movement based on servers’ workload. + +**Special keys in system key space**: DD saves its state in system keyspace to recover from failure and to ensure every process (e.g., proxies, tLogs and storage servers) has a consistent view of which storage server is responsible for which key range. + +*serverKeys* sub-space (\xff/serverKeys/): It records the start key of each shard a server is responsible for. The format is *\xff/serverKeys/[serverID]/[start_key]*. To get start keys of all shards for a server, DD can read the key range with prefix *\xff/serverKeys/[serverID]/*. + +*keyServers* sub-space (\xff/keyServers/): It records each key’s source and destination server IDs. The format is \xff/keyServers/[start_key]/[src_server][dst_server], where [start_key] is the start key of a shard, [src_server] are the servers responsible for the shard, [dst_server] are the new servers where the shard will be moved to when relocating shard request is initialized. To get all source and destination servers for the shard, DD can read the key range with the prefix \xff/keyServers/[start_key]. To get each shard’s boundary, DD can read the key range with the prefix \xff/keyServers/ and collect all [start_key]s. Two consecutive [start_key] construct the key range for a shard. + +*moveKeysLockOwnerKey* (`\xff``/moveKeysLock/Owner`) and *moveKeysLockWriteKey* (`\xff``/moveKeysLock/Write`): When DD moves keys, it must grab the moveKeysLock, which consists of an owner key and a write key. The owner key (i.e., moveKeysLockOwnerKey) specifies which DD currently owns the lock. The write key (i.e., moveKeysLockWriteKey) specifies which DD is currently changing the mapping between keys and servers (i.e., operating on serverKeys and keyServers subspace). If DD finds it does not own both keys when it tries to move keys, it will kill itself by throwing an error. Cluster controller will recruit a new one. + +When a new DD is initialized, it will set itself as the owner by setting its random UID to the moveKeysLockOwnerKey. Since the owner key has only one value, at most one DD can own the DD-related system subspace. This avoids the potential race condition between multiple DDs which may co-exit during DD recruitment. + +**Transaction State Store (txnStateStore)**: It is a replica of the special keyspace that stores the cluster’s states, such as which SS is responsible for which shard. Because proxies use txnStateStore to decide which tLog and SS should receive a mutation, proxies must have a consistent view of txnStateStore. Therefore, changes to txnStateStore must be populated to all proxies in total order. To achieve that, we use the special transaction (applyMetaMutations) to update txnStateStore and uses resolver to ensure the total ordering (serializable snapshot isolation). + +**Private mutation**: A private mutation is a mutation updating a special system key, such as keyServersKey (\xff/keyServers/) and serverKeysKey (\xff/serverKeys/). Like a normal mutation, a private mutation will be processed by the transaction systems (i.e., proxy, resolver and tLog) and be routed to a set of storage servers, based on the mutation’s tag, to update the key-value in the storage engine. Private mutations also keep the serializable snapshot isolation and consensus: The results of committed concurrent private mutations can be reproduced by sequentially executing the mutations, and all components in FDB have the same view of the mutations. + + +## Operations + +Operations on the states (and data structure) of DD are done in actors. Each actor is responsible for only a specific task. We will describe the most important actors in this section. + +**Storage server tracker (storageServerTracker)**: Whenever a storage server is created, a storage server tracker is created for the server. The tracker monitors the status (e.g., healthiness) of the server. When a server becomes unhealthy or the server’s process dies, the tracker issues the request to remove data on the server. Once all data are moved away from the server, the tracker remove the servers’ information from DD. When a server’s storage interface changes -- because the storage process reboots or moved -- the tracker updates the server’s information and change the server’s teams accordingly to ensure the replication policy is always satisfied. + +**Team tracker (teamTracker)**: Whenever a server team is created, a team tracker is created to monitor the healthiness of the team. When a healthy team becomes unhealthy, the team tracker will find all shards on the team, create the RelocateShard requests, and send the requests to the dataDistributionQueue. + +**Team builder (buildTeams)**: Team builder is created when DD is initialized. It is invoked by the following events: (a) a new server is created and added to DD; (b) an existing server is removed from DD; (c) there is zero teams in the system. + +Whenever the team builder is invoked, it aims to build the desired number of server teams. To ensure each server team belongs to a machine team, it first builds the desired number of machine teams; it then picks a machine team and picks a server from each machine in the machine team to form a server team. + +**Data distribution queue server (dataDistributionQueue actor)**: It is created when DD is initialized. It behaves as a server to handle RelocateShard related requests. For example, it waits on the stream of RelocateShard. When a new RelocateShard is sent by teamTracker, it enqueues the new shard, and cancel the inflight shards that overlap with the new relocate shard. + +**applyMetaMutations:** It is a special logic to handle *private transactions* that modifies txnStateStore and special system keys. Transaction system (i.e., proxy, resolver and tLogs) and storage servers perform extra operations for the special transactions. For any update, it will be executed on all proxies in order so that all proxies have a consistent view of the txnStateStore. It will also send special keys to storage servers so that storage servers know the new keyspace they are now responsible for. + +A storage server (SS) processes all requests sent to the server in its storageServerCore actor. When a (private) mutation request is sent to a SS, the server will call the update() function. Eventually, the StorageUpdater class will be invoked to apply the mutation in applyMutation() function, which handles private mutations applyPrivateData() function. + +If a new key range is assigned to a storage server, the storage server will receive a private mutation that changes the *serverKeys *(\xff/serverKeys/) and *keyServers* (\xff/keyServers/). Then the server will create transactions, just as an FDB client, to read key-value pairs in the assigned key range and write the data into its local storage engine. + +If a key range is removed from a storage server, similarly the storage server will receive a private mutation that changes the *serverKeys* and *keyServers*. Once the private mutation is processed by the SS, the SS removes data in its versioned data. + + +## Mechanisms + +### How is data distribution initialized? + +When a data distribution role is created, it recovers the states of the previous DD from the system keyspace. First, it sets itself as the owner of the moveKeysLock. Then it collects the information of servers and shards, the map between servers and shards, and the replication configuration by reading DD-related system keyspace (i.e., *serverKeys* sub-space). Based on the information, the new DD recreates its components (e.g., servers, teams, and trackers) that matches the states of the previous DD. Trackers will evaluate the healthiness of servers and teams based on the replication policy. Unhealthy servers and teams will be removed and new servers and teams will be created if the replication policy is changed. + +### When to move keys? + +Keys can be moved from a server to another for several reasons: (a) DD moves keys from overutilized servers to underutilized servers, where a server’s utilization is defined as the server’s disk usage; (b) DD splits or merges shards in order to rebalance the disk usage of servers; (c) DD removes redundant teams when the team number is larger than the desired number; (d) DD repairs the replication factor by duplicate shards from a server to another when servers in a team fail. + +Actors are created to monitor the reasons of key movement: (a) MountainChopper and ValleyFiller actors periodically measure a random server team’s utilization and rebalance the server’s keys among other servers; (b) shardMerger and shardSplitter actors take a shard as input and respectively evaluates if the input shard can be merged with its neighboring shards without creating a too big shard and if the shard should be split. Once new shards are created, the actors create the shard’s tracker and send RelocateShard requests to DD’s queue; (c) serverTeamRemover and machineTeamRemover actors periodically evaluate if the number of server teams and machine teams is larger than the desired number. If so, they respectively pick a server team or a machine team to remove based on predefined criteria; (d) teamTracker actor monitors a team’s healthiness. When a server in the team becomes unhealthy, it issues the RelocateShard request to repair the replication factor. The less servers a team has, the higher priority the RelocateShard request will be. + +### How to move keys? + +A key range is a shard. A shard is the minimum unit of moving data. The storage server’s ownership of a shard -- which SS owns which shard -- is stored in system keyspace *serverKeys *(\xff/serverKeys/) and *keyServers* (\xff/keyServers/). To simplify the explanation, we refer to the storage server’s ownership of a shard as a shard’s ownership. + +Shard’s ownership is used in transaction systems (proxy and tLogs) to route mutations to tLogs and storage servers. When proxy receives a mutation, it uses the shard’s ownership to decide which *k* tLogs receive the mutation, assuming *k* is the replias factor. When a storage server pulls mutations from tLogs, it uses the shard’s ownership to decide which shards the SS is responsible for and which tLog the SS should pull the data. + +Shard’s ownership must be consistent across transaction systems and SSes, so that mutations can be correctly routed to SSes. Moving keys from a SS to another requires changing the shard’s ownership under ACID property. The ACID property is achieved by using FDB transactions to change the *serverKeys *(\xff/serverKeys/) and *keyServers* (\xff/keyServers/). The mutation on the *serverKeys *and* keyServers *will be categorized as private mutations in transaction system. Compared to normal mutation, the private mutations will change the transaction state store (txnStateStore) that maintains the *serverKeys *and* keyServers *for transaction systems (proxy and tLog) when it arrives on each transaction component (e.g., tLog). Because mutations are processed in total order with the ACID guarantees, the change to the txnStateStore will be executed in total order on each node and the change on the shard’s ownership will also be consistent. + +The data movement from one server (called source server) to another (called destination server) has four steps: (1) DD adds the destination server as the shard’s new owner; (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; (4) DD removes the shard’s information owned by the source server from the server’s team information (i.e., *shardsAffectedByTeamFailure*).
