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.
> Support atomic region operations

> 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.
