Jonathan Gray commented on HBASE-880:
-------------------------------------
We're trying to build at least some sense of consensus here before moving
forward full steam.
ken gave a semi-blessing... stack is cool as long as we explain it, code it and
test it... so with jd's semi-blessing, i'd say we're ready to move towards a
patch.
A complete rework of HRegion is currently underway as part of HBASE-1234, so
the server-side part of this will have to remain psuedo-code until the switch
to KeyValue is complete.
We have a good bit of the client side done, will get a first patch together
this week.

> The current API does not scale very well. For each new feature, we have to
> add many methods to take care of all the overloads. Also, the need to batch
> row operations (gets, inserts, deletes) implies that we have to manage some
> "entities" like we are able to do with BatchUpdate but not with the other
> operations. The RowLock should be an attribute of such an entity.
> The scope of this jira is only to replace current API with another
> feature-compatible one, other methods will be added in other issues.
