Edward Bortnikov commented on HBASE-16608:
------------------------------------------
Thanks again, [~anoop.hbase] and [~ram_krish] for helping us debug the GC
issue. Agree that the current merge policy is naive. The number of ref copies
and waste memory grows as arithmetic progression with the number of flushes.
Let's try to find middle ground between the need to keep the number of segments
small and the need to reduce the copy. Looking forward to that conversation.

> SQM usage
