Subject [jira] [Commented] (HBASE-5699) Run with > 1 WAL in HRegionServer

    [ https://issues.apache.org/jira/browse/HBASE-5699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14089495#comment-14089495

Anoop Sam John commented on HBASE-5699:
---------------------------------------

Yes, the grouping logic should be a pluggable module. The grouping can be per table regions
wise or on all regions. It should be inline with balancing strategy. (per table or not)

bq.To replay locally we should avoid the RPC itself totally? Is it possible in the new distributed
log replay?
Have not checked deeply with code. These are like high level thoughts only. We can check more.
If we can avoid RPCs in the replay that would be great IMO.
