-Re: Should compaction be triggered even if User periodically flushes
Thanks for your reply. My concern is not with respect to compaction
happening when a region is opening in another RS, my point was though the
flushes were happening and more storefiles are created
by user initiated flushing, the compaction were not getting triggered.
