Subject [jira] [Commented] (HBASE-5542) Unify HRegion.mutateRowsWithLocks() and HRegion.processRow()
Date Fri, 09 Mar 2012 19:37:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13226368#comment-13226368

Lars Hofhansl commented on HBASE-5542:
--------------------------------------

Can we let this sit for a bit. I would like to spend some time thinking about this. doMiniBatchPut
almost follows the same logic, should be able to unify that code as well. It's not needed
for 0.94, so it's not time critical.

Thanks for working on this Scott!

> 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.
