Misty Stanley-Jones updated HBASE-13883:
----------------------------------------
Attachment: HBASE-13883.patch
This is not talking about MultiWAL but just about the number of log entries in
the WAL. This patch should add some clarity, and also improves the formatting
of the list.

> 65.7.2. MemStore Flush
> A MemStore flush can be triggered under any of the conditions listed below.
> The minimum flush unit is per region, not at individual MemStore level.
> // SKIPPED
> 3. When the number of WAL per region server reaches the value specified
> in hbase.regionserver.max.logs, MemStores from various regions will be
> flushed out to disk to reduce WAL count. The flush order is based on time.
> Regions with the oldest MemStores are flushed first until WAL count drops
> below hbase.regionserver.max.logs.
> {quote}
> Section 3. requires clarification (reference to HBase version which supports
> this). Is it MultiWAL feature in 1.0?
