Jim Kellerman commented on HBASE-44:
------------------------------------
Doğacan,
I agree that this satisfies HBASE-31. Even though we drag over cell contents,
it is highly likely (at least in the applications I've seen) that the client
application will use the cell contents more often than not.
I think that the best reason for this issue to be pushed to 0.20.0 is that it
will be a whole lot easier with the new api (HBASE-880) in place.

> If you have rows that are densely populated (most versions have all the
> columns) and heavily versioned, and if you are doing things like checking
> difference between the versions, it would be really handy to be able to get
> all of the versions and data at once. This method would let you do that.

> Map<long, Map<Text, byte[]>> getRowTimestampsWithColumns(Text row, Text[]
> columns, long timestamp);
