Vladimir Rodionov updated HBASE-14388:
--------------------------------------
Attachment: HBASE-14388-v1.patch
* Periodic memstore flush changes
New configuration option: *hbase.regionserver.flush.jitter*. Default value:
0.5. This affects memstore flush interval
(*hbase.regionserver.optionalcacheflushinterval*) and maximum changes per flush
(*hbase.regionserver.flush.per.changes*) by randomizing them. After every flush
operation, the new random value is assigned to memstore flush interval and to
maximum changes per flush.
* Maximum WAL files changes
The configuration option *hbase.regionserver.maxlogs* is obsolete. The maximum
number of WAL files is defined now dynamically:
{code}
maxLogs = HEAP_SIZE * memstoreRatio * 2/ LogRollSize
{code}
> Compaction improvements: Avoid flush storms by jittering flush interval and
> max log files
