Andrew Purtell commented on HBASE-10772:
----------------------------------------
bq. Currently we don't have any offheap based BR. So if we try to create a BR
that is backed by DBB and to ensure the current behaviour works of BR pools etc
we may need such things in BR also
I suggest trying a BR backed by a DBB and adding only the minimum of what is
needed.
> Use ByteRanges instead of ByteBuffers in BlockCache

> Try replacing the BBs with Byte Ranges in Block cache. See if this can be
> done in a pluggable way.
