ryan rawson commented on HBASE-2368:
------------------------------------
one thing to keep in mind is we do not offer atomic guarantees for multiple
rows or API calls. Suggesting that we do would be contrary to the actual
situation on the ground.
Maybe Kay Kay can describe the specific performance problem he is having and we
can come up with a great way that makes everyone happy?
> BulkPut - Writable class compatible with TableRecordWriter for bulk puts
> agnostic of region server mapping at Mapper/Combiner level

> TableRecordWriter currently accepts only a put/delete as writables. Some
> mapper processes might want to consolidate the 'put's and insert them in
> bulk. Useful in combiners / mappers - to send across a bunch of puts from one
> stage to another , while maintaining a very similar region-server-mapping
> agnostic api at respective levels.
> New type - BulkPut ( Writable ) introduced that is just a consolidation of
> Puts. Eventually , the TableRecordWriter bulk inserts the puts together into
> the hbase eco-system.
> Patch made against trunk only. But since , it does not break any backward
> compatibility - it can be an useful addition to the branch as well.
> Let me know your comments on the same.
