Enis Soztutar commented on HBASE-13063:
---------------------------------------

We can also document this in the book. There is a section for region replicas already with
all config options.

> 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}
