Matteo Bertozzi commented on HBASE-13063:
-----------------------------------------
{quote}Don't you think we should be setting the default flag to false?{quote}
nah, in theory you expect the replica to be quite up to date.
this flag is just if your client can stay behind "a lot" and it is aware of
that.
{quote} May be a good idea to initialize with null as you are checking for null
in requiresReplication?{quote}
sure.. I'll add that. but null is the default value
http://docs.oracle.com/javase/specs/jls/se7/html/jls-4.html#jls-4.12.5
{quote}Also, it would be a good idea to ad LOG statement saying whether
memstore replication is enabled/disabled.{quote}
since we don't have a sink object for each table, it will require adding a set
or something to print the log only once. not sure if it is worth.

> 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}
