Sergey Shelukhin commented on HBASE-9648:
-----------------------------------------
Yeah, that is what we recommended :)
Deleting the file definitely makes sense, we can shortcut and archive it
immediately without any compaction.
At that point there's also no need to do convoluted checks because we also have
full view of all files.

> There's a shortcut in compaction selection that causes the selection of
> expired store files to quickly delete.
> However, there's also the code that ensures we write at least one file to
> preserve seqnum. This new empty file is "expired", because it has no data,
> presumably.
> So it's collected again, etc.
> This affects 94, probably also 96.
