Kay Kay updated HBASE-2368:
---------------------------
Description:
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.
