> As per that Jira, we keep only requestCompaction API in Region. We did not
> have any such for flush in Region. Only API which was there is a flush which
> will block the callee unless flush is done. This issue has to tacke
> 1. Decide whether we need a requestFlush in Region and if so add
> 2. Whether the requestCompaction (And requestFlush too) should return a
> Future? Right now the former do not return any but allow to pass a
> CompactionLifeCycleTracker which will get notified on start and end of
> compaction.
