Evan Tschannen b6008558d3 renamed BinaryWriter.toStringRef() to .toValue(), because the function now returns a Standalone<StringRef>()
eliminated an unnecessary copy from the proxy commit path
eliminated an unnecessary copy from buffered peek cursor

Balachandar Namasivayam 5471725db5 Support config where the primary and remote DC's can be used as satellites. 2019-03-18 12:17:59 -07:00
Evan Tschannen a2108047aa removed LocalitySetRef and IRepPolicyRef typedefs, because for clarity the Ref suffix is reserved for arena allocated objects instead of reference counted objects. 2019-03-13 13:14:39 -07:00

Merge pull request #1160 from alexmiller-apple/tstlog-fork
Spill-By-Reference TLog Part 2: New and Old TLogServers co-exist harmoniously
2019-02-26 18:00:04 -08:00
Alex Miller 2dc57568cb Change many things about log_version.
* log_version in the database (`/conf/log_version`) is now a hint that gets
  rounded to the nearest supported version.
* fdbcli and FDB enforce that only a valid log_version can be configured to
* TLogVersion is persisted in CoreTLogSet (and LogSet and TLogSet)
* Some comments here and there
* Add an assert on filename length to make sure KV-pairs in filename
  don't exceed a maximum length.

Evan Tschannen 0e19b5a935 fix: allow the txnStateStore to be recovered from a process in a down datacenter, so that the cluster controller can know to switch to the other region 2019-02-21 16:52:27 -08:00
mpilman 3f0fd2a20c Use fwd decls in WorkerInterface
Also WorkerInterface.h -> WorkerInterface.actor.h
2019-02-19 15:16:59 -08:00
Evan Tschannen 9cfadad41b fix: if the tagPartitionedLogSystem cannot do a forced recovery, the master should not execute it forced recovery based modifications either 2019-02-18 15:13:18 -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 e7e1c634e0 fix: we need to restart the peek cursor when the known committed version becomes available 2018-10-02 17:44:14 -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 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 cd63c7a7cc added a buffered cursor, which efficiently merges lots of peek cursors 2018-07-12 12:09:48 -07:00
Evan Tschannen c148c865e3 optimized log peek cursors to use much less CPU when using the policy engine 2018-07-11 15:43:55 -07:00
Evan Tschannen 6cf5354425 checkSatelliteTagLocations is not an error if the same zoneId is used multiple times 2018-07-05 13:00:13 -07:00
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 fb0d10635d the first location in a satellite team is the one that will serve peek requests. Make sure we probably balance peek traffic by having the first servers on each team be used an equal amount of times 2018-06-27 22:14:50 -07:00
Evan Tschannen 00167b0157 renamed some uses of knownCommittedVersion to durableKnownCommittedVersion
epochEnd exclusively refers to the last version a set of logs is responsible for serving peek requests for
recoverAt and recoveredAt refer to the last committed version of the previous generation

Evan Tschannen 50e1e03130 fix: for configurations with anti-quorums to work, the push actors need to be put in the proxy’s actor collection 2018-06-18 15:25:54 -07:00
Evan Tschannen f637c680f1 fix: populateSatelliteTagLocations was broken
fix: satellites do not index the upgraded locality
2018-06-17 13:29:17 -07:00
Evan Tschannen 6931a00993 satellite log push locations are static per tag, which will reduce the number of tags each satellite log has to index, and reduce the proxy cpu when calculating push locations 2018-06-16 17:39:02 -07:00
Evan Tschannen f694f7c9ca removed hasBestPolicy 2018-06-15 12:36:19 -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.
