stack commented on HBASE-15179:
-------------------------------

[~anoop.hbase] doesn't write path require bucketcache? How about a bit of 
user-doc for the refguide on how to enable? (though I thought we wanted this 
enabled by default? Maybe enabling by default comes later, in 2.1.....?)

> Cell/DBB end-to-end on the write-path

> Umbrella jira to make the HBase write path off heap E2E. We have to make sure 
> we have Cells flowing in entire write path. Starting from request received in 
> RPC layer, till the Cells get flushed out as HFiles, we have to keep the Cell 
> data off heap.
