> It is important that compacted storefiles of a given compaction execution are
> wholly opened or archived to insure data consistency. ie a storefile
> containing delete tombstones can be archived while older storefiles
> containing cells that were supposed to be deleted are left unarchived thereby
> undeleting those cells.
> When a server fails compaction markers (in the wal edit) are used to
> determine which storefiles are compacted and should be excluded during region
> open (during failover). But the WALs containing compaction markers can be
> prematurely archived even though there are still compacted storefiles for
> that particular compaction event that hasn't been archived yet. Thus losing
> compaction information that needs to be replayed in the event of an RS crash.
> This is because hlog archiving logic only keeps track of flushed storefiles
> and not compacted ones.
