Subject [jira] [Commented] (HBASE-17081) Flush the entire CompactingMemStore content to disk

Anastasia Braginsky commented on HBASE-17081:
---------------------------------------------

Good day everybody! :-)

I think the way it is implemented now is quite OK. However I am going to publish the new patch
today where CompositeImmutableSegment is going to work (and has interfaces) which is even
more close to the Segment. 
Let take a look on it soon and you will tell me your opinion then. I think we are quite close
to an optimal solution and it is going to be good! :)

> Part of CompactingMemStore's memory is held by an active segment, and another part is
divided between immutable segments in the compacting pipeline. Upon flush-to-disk request
we want to flush all of it to disk, in contrast to flushing only tail of the compacting pipeline.
