Subject [jira] [Commented] (HBASE-5229) Support atomic region operations
Date Sun, 22 Jan 2012 01:17:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13190572#comment-13190572

Lars Hofhansl commented on HBASE-5229:
--------------------------------------

A real patch is a bit more complicated, as there are multiple regions and stores. The ClientScanner
still needs to address the correct region, and all unneeded stores need to be skipped.

> As discussed (at length) on the dev mailing list with the HBASE-3584 and HBASE-5203 committed,
supporting atomic cross row transactions within a region becomes simple.
> I am aware of the hesitation about the usefulness of this feature, but we have to start
somewhere.
> Let's use this jira for discussion, I'll attach a patch (with tests) momentarily to make
this concrete.
