Subject [jira] [Commented] (HBASE-5542) Unify HRegion.mutateRowsWithLocks() and HRegion.processRow()
Date Mon, 12 Mar 2012 22:00:40 GMT

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

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

  In the latest patch I can't find rowProcessorTimeout being set anywhere.

  What I had in mind was this:
  We are now using this for "internal" operations (such as mutateRow) and "external" operations
(those created by users). The internal operations should not be creating new threads. External
operations either could always time bound or it could be up to the implementer.

> 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.
