---------------------------------------------

Hey Again!

I have answered all the comments in the RB. Please take a look and comment if you do not agree
with my answers. 

If you have already presented about pipeline flush and it's perf numbers, please show us where
(JIRA?), because we are not aware. I am OK to proceed with your patch, but please upload it
now for our review. Otherwise, I am going to proceed with developing this patch and I do not
want to spend my time.

> 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.
