Subject [jira] [Commented] (HBASE-13063) Allow to turn off memstore replication for region replicas

Matteo Bertozzi commented on HBASE-13063:
-----------------------------------------

[~stack] first run and pre-commit hook didn't fail https://builds.apache.org/job/HBase-TRUNK/6234/
- locally it seems to work, let me see if I'm missing something.

> HBASE-11568 allows to use replication to send wal edits from the primary to the replicas.
> sometimes the memstore replication is not required, so it will be nice have a flag to
disable it.
> the result will be more or less the same to what we have in phase-1, but with the row-level
consistency provided by the "flush" edit transfered via replication to refresh the hfiles.
> create 't1', 'f', {REGION_REPLICATION => 2, REGION_MEMSTORE_REPLICATION => false}
