> Currently, HBase deletes the out of TTL store files after compaction. We can change the
sequence to delete the out of TTL store files before selecting store files for compactions.

> In this way, HBase can keep deleting the old invalid store files without compaction,
and also prevent from unnecessary compactions since the out of TTL store files will be deleted
before the compaction selection.
