Jonathan Gray commented on HBASE-2368:
--------------------------------------
I agree with Ryan. We currently support write buffers and also you can use
List<Put> on an HTable already (though not to TOF).
For the default TOF case, this wouldn't actually behave any differently than
just issuing individual Puts and allowing the underlying write buffer to
process them in bulk.
> 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.
