stack updated HBASE-10204:
--------------------------
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.
