[jira] [Comment Edited] (HBASE-18070) Enable memstore replication
for meta replica
[ https://issues.apache.org/jira/browse/HBASE-18070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17168331#comment-17168331 ]

Yeah, we checked the phase 2 design of read replica, there will be no out of order for meta replica replication. 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.
