Subject [jira] [Commented] (HBASE-5542) Unify HRegion.mutateRowsWithLocks() and HRegion.processRow()

Phabricator commented on HBASE-5542:
------------------------------------

lhofhansl has commented on the revision "HBASE-5542 [jira] Unify HRegion.mutateRowsWithLocks()
and HRegion.processRow()".

  @Scott: Yes, let's use another jira for doMiniBatchPut.
  For the timebound logic, at the very least there has to be an option to not do that for
mutateRowsWithLocks, as spawning another thread for that would be too expensive.

> mutateRowsWithLocks() does atomic mutations on multiple rows.
> processRow() does atomic read-modify-writes on a single row.
> It will be useful to generalize both and have a
> processRowsWithLocks() that does atomic read-modify-writes on multiple rows.
> This also helps reduce some redundancy in the codes.
