Jingyu Zhou 886e7ab2ba Add a new DataDistributor role.
Let cluster controller to start a new data distributor role by sending a
message to a chosen worker.
Change MasterInterface usage in DataDistribution to masterId

Add DataDistributor rejoin handling.

This allows the data distributor to tell the new cluster controller of its
existence so that the controller doesn't spawn a new one. I.e., there should
be only ONE data distributor in the cluster.

If DataDistributor (DD) doesn't join in a while, then ClusterController (CC) tries
to recruit one as DD. CC also monitors DD and restarts one if it failed.

The Proxy is also monitoring the DD. If DD failed, the Proxy will ask CC for
the new DD.

Add GetRecoveryInfo RPC to master server, which is called by data distributor
to obtain the recovery Transaction version from the master server.

Evan Tschannen 6bb283aebc fix: dcId to Locality changes could be lost if an emergency transaction happened that did not change the configuration
fix: master proxy was starting dcId’s at 1 number too large

Evan Tschannen 87295cc263 suppressed spammy trace events, and avoid reporting a long master recovery duration when the cluster is first created 2018-11-04 23:07:56 -08:00
Robert Escriva 268093a96d Adjust all includes to be relative to the root.
Remove the use of relative paths.  A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h".  Adjust so that every include references such a header with the
latter form.

Evan Tschannen cdaf5e1192 fix: forced recovery does not recover tags from any DC besides the surviving one 2018-10-02 17:46:22 -07:00

Evan Tschannen 05e7f08b26 added a peek method which will attempt to read the txsTag from the local region as much as possible 2018-09-28 12:21:08 -07:00
Evan Tschannen 200e65fe61 added a workload which tests killing an entire region, and recovering from the failure with data loss.
fix: we cannot pop the txs tag from remote logs until they have a full copy of the txnStateStore
fix: we have to modify all of history, we cannot stop after finding a local remote

Evan Tschannen 90bf277206 require key value store memory to recover cleanly when recovering the txnStateStore, since all of the data it is recovering has been fsync’ed 2018-08-31 13:07:48 -07:00
A.J. Beamon 2a97139d5d This is the first step in eliminating the usage of database names in our code. The C API remains the same, but underneath that all usage of database names is eliminated. 2018-08-16 10:24:12 -07:00
Alex Miller fb31a6999f Rewrite all files to have #include actorcompiler.h as the last include. 2018-08-14 15:50:26 -07:00
Alex Miller 535b5701e5 Rewrite all `Void _ = wait(...)` -> `wait(...)`.
This takes advantage of the new actorcompiler functionality to avoid
having duplicate definitions of `Void _` when trying to feed the
un-actorompiled source through clang.

Evan Tschannen 9d0a07a400 fix: trackLatest for master recovery state was wrong, causing status to report incorrect recovery states 2018-08-04 12:50:56 -07:00
Evan Tschannen 30b2f85020 fix: it is not safe to drop logs supporting the current primary datacenter, because configuring usable_regions down will drop the storage servers in the remote region, leaving you will no remaining logs 2018-07-14 16:26:45 -07:00

Evan Tschannen da5a232d7e fix: If we have not recruited the remote logs yet and detect a configuration change, we must fail the master to update the remote recruitment request 2018-07-05 12:17:41 -07:00
Evan Tschannen 507b3bacb0 fix: kill all tlogs in one region prevents the remote logs from recovering in that region, do not allow that to prevent us from configuring usable_regions=1.
added more recovery states.
2018-07-05 00:08:51 -07:00
Evan Tschannen 866ccfe344 added the ability to allow the master to finish recovery before all storage servers in both regions have their mutations. This allows you to recover from scenarios where you lose all your tlogs in one dc. 2018-07-04 01:59:04 -04:00
Evan Tschannen 3c9f3da980 fix: usable regions cannot be changed during an emergency transaction, because it could lead to all storage servers dying if the previous primary is dead 2018-07-01 23:59:06 -04:00
Evan Tschannen 7a12d3e130 added the (untested) ability to force a recovery to the remote datacenter, even if that results in data loss. If the DR lag is more than 1 week there could be potential data corruption if any primary storage servers are still alive. 2018-07-01 09:39:04 -04:00
Evan Tschannen 8a8914f046 re-added the ability to configure the number of log routers. Many log routers are needed to get a sufficient number of sockets involved in copying data across the WAN 2018-06-22 00:04:00 -07:00
Evan Tschannen 0913368651 added usable_regions to specify if we will replicate into a remote region
remote replication defaults to the primary replication
removed remote_logs, because they should be specified as an override in the regions object
2018-06-17 19:31:15 -07:00
Evan Tschannen 284233baa1 added a key in the database with the locality of the current master 2018-06-14 19:36:02 -07:00
Evan Tschannen fbb3f85c74 fix: logsKey was not being updated properly 2018-06-14 12:54:39 -07:00
Evan Tschannen 889889323e The master will tell the cluster controller if it is going to take a long time to recruit new logs in its DC; the cluster controller can determine if the other DC would be better and recruit there.
The cluster controller will not switch to the other data center if remote logs are too far behind.
We will not recruit in DCs with negative priority.

Alex Miller fcfa00928b Make RecoveryState an enum class.
This means that all the == 7 or != 0 checks go away, and explicit names must be used.
2018-06-12 16:50:25 -07:00
A.J. Beamon e5488419cc Attempt to normalize trace events:
* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.

Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.

This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.

Evan Tschannen b1935f1738 fix: do not allow a storage server to be removed within 5 million versions of it being added, because if a storage server is added and removed within the known committed version and recovery version, they storage server will need see either the add or remove when it peeks 2018-05-05 18:16:28 -07:00
Evan Tschannen 35b2ca820a fix: certain tlog errors during remote recovery could fail to kill the master, the master could have a reference counting cycle with its actor collection 2018-04-24 16:10:14 -07:00
Evan Tschannen 73597f190e fix: new tlogs are initialized with exactly the tags which existed at the recovery version 2018-04-22 20:28:01 -07:00
Evan Tschannen 3018a7b1b3 fix: the known committed version of a newly initialized log is 1, since by definition the first commit must have succeeded 2018-04-16 10:42:48 -07:00

Evan Tschannen 65b532658f added support for single region configurations 2018-03-15 10:59:30 -07:00
Evan Tschannen 8c88041608 fix: we must commit to the number of log routers we are going to use when recruiting the primary, because it determines the number of log router tags that will be attached to mutations 2018-03-06 16:31:21 -08:00
Evan Tschannen 1194e3a361 added region-based configuration to support a large variety of fearless setups. Currently only 1 primary 1 remote setups are allowed. 2018-03-05 19:27:46 -08:00
Evan Tschannen 470f5c01f3 changed remoteDcId to a vector of ids, to support future configurations where there are multiple remote databases 2018-02-26 17:09:09 -08:00
