Description

This is an umbrella issue under which we tie all efforts at offheaping whether apurtell and crews' effort at single off-heap allocation arena for blockcache and memstore (includes reading from dfsclient into DBBs which are then put into an offheap block cache) through @nkeywal reading queries into direct bytebuffers.

This issue should include links to discussion and design. It also should host targets such as that posited by vrodionov in HBASE-10191 where going end-to-end offheap would imply a new read/write pipeline.
