Anastasia Braginsky commented on HBASE-17081:
---------------------------------------------
[~ram_krish], in your review comments you are saying:
bq. So you arrived at 10 after some experiments? When I did experiments with >
6 I found things to be performing lesser. I will get those reports if I have
with me.
We actually didn't try something between 1 and 10... So are you saying that you
have seen a performance degradation from having more than 6 segments in the
compacting pipeline? Do you really have reports? Do you remember any numbers?
> Flush the entire CompactingMemStore content to disk

> 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.
