The backup container can figure out if partitioned logs are used by looking at
mutation logs, thus consolidating the API to a single describeBackup() as
before.
To pause/resume the backup workers, the fdbbackup command will write to the
backupPausedKey. Then backup workers noticed the value of the key has been
changed and stops/resumes pulling from TLog.
For partitioned logs, computing continuous log end version from min logs begin
version. Old backup test keeps using describeBackup() to be correctness clean.
Rename partitioned log file so that the last number is block size.
The backup container behavior was changed at commit 604ad062d5.
The new behavior was not applied in BackupAndParallelRestoreCorrectness.actor.cpp.
This can cause test failure due to backup cannot find a valid backup container.
1. Review memory use cases and improve:
Ensure state varialble is initialized and
change unnecessary state variable to variable.
2. Remove debug code that is no longer useful;
3. Mute verbose debug.
1) Use map iterator instead of pointer to maintain stability when map is inserted or deleted
2) dummySampleWorkload: clear rangeToApplier data in each sampling phase. otherwise, we can
have an increasing number of keys assigned to the applier.
1) Should recruit only configured number of roles;
2) Should never register a restore master interface as a restore worker (loader or applier) interface.
1) Use the runRYWTransaction for simple DB access
2) Replace some printf with TraceEvent
3) Remove printf not used in debugging
4) Avoid wait inside the condition in loop-choose-when for
the core routine of restore worker, loader and applier.
5) Rename Restore.actor.cpp to RestoreWorker.actor.cpp since
the file only has functionalities related to restore worker.
Passed correctness test
Add a NotifiedVersion into an applier data which represents
the smallest version the applier is at.
When a loader sends mutation vector to appliers, it sends
the request that contains prevVersion and commitVersion.
This commits also put actor into an actorCollector for
loop-choose-when situation.
