Phabricator updated HBASE-5199:
-------------------------------
Attachment: D1311.4.patch
Liyin updated the revision "[jira][HBASE-5199] Delete out of TTL store files
before compaction selection ".
Reviewers: Kannan, JIRA, khemani, aaiyer, Karthik
During the minor compaction selection time, if there is any expired store
files, these expired store files will be selected to compact directly.
Since these files have already expired, there would be no-ops during the
compaction time and these files will be deleted after the compaction.

> 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.
