Lars Hofhansl commented on HBASE-5229:
--------------------------------------
Thanks Philip. Yep, that's the idea with this. Global transactions would be
handled differently and be *far* more heavyweight (and must be used judiciously
or your load will not scale).
The transactions I have in mind with this would be just as fast as a current
Puts/Deletes (with the drawback that related data would be collocated).

> 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.
