Huaxiang Sun commented on HBASE-18070:
--------------------------------------
Yeah, we checked the phase 2 design of read replica, there will be no out of
order for meta replica. Yeah, it will only be used for region location for
hbase client, not something else. For master's view of meta, it can always talk
with primary meta replica (just like there is no replica for meta).
Most of logic/foundation has been laid out by phase 2 of read replica, we are
trying to put some glue logic for meta and some optimizations for this special
case.
> Enable memstore replication for meta replica
