Subject [jira] [Commented] (HBASE-3584) We need to atomically put/delete/increment in one call
Date Thu, 12 Jan 2012 21:21:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3584?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13185243#comment-13185243
] 

Lars Hofhansl commented on HBASE-3584:
--------------------------------------

Also this patch only addresses this for Put and Delete. Increment (and Append) do not adhere
to mvcc (and cannot be easily made so), so wrapping them into an single atomic operation is
(currently) pointless.

> Right now we have the following calls:
> put(Put)
> delete(Delete)
> increment(Increments)
> But we cannot combine all of the above in a single call, complete with a single row lock.
 It would be nice to do that.
> It would also allow us to do a CAS where we could do a put/increment if the check succeeded.
