stack commented on HBASE-880:
-----------------------------
No. I was thinking about this wrong fixated on current HTable getScanners API.
If I adopt your suggestion, the HTable API would change so column names would
be specified in this new Map of columns to Scopes.
One thought is that we should probably check for case where Map includes a
Scope for a column and for its enclosing family and throw an exception if a
Client attempts such a specification?
> Improve the current client API by creating new container classes

> 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.
