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

ramkrishna.s.vasudevan commented on HBASE-17081:
------------------------------------------------

bq.If there is still some problem with a specific test that requires being run with no compaction,
t
This is one simple reason why we think we cannot enable by default. Also enabling BASIC by
default for all cases am not sure if that is what is going to happen when there is really
no duplicates in the actual user workload.

> 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.
