> HBASE-10141 is a good optimization, eliminating the need to scan already
> expired files (through TTL). However, I think if MIN_VERSIONS is set, it will
> not ensure that there will be at least that many versions since it bypasses
> the scan layer.
> I think we can just do a simple check before the HBASE-10141 optimization to
> see whether MIN_VERSIONS is set for the table, and if so just do the regular
> old way of doing the scan in the compaction.
