Jean-Daniel Cryans commented on HBASE-880:
------------------------------------------

+1 on current proposal. When changing the batching methods, it would be good to specify that the row lock will apply to all rows.

> 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.
