[jira] [Updated] (HBASE-5199) Delete out of TTL store files before compaction selection

     [ https://issues.apache.org/jira/browse/HBASE-5199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Liyin Tang updated HBASE-5199:
------------------------------

    Description: 
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.

  was:
Currently, HBase deletes the out of TTL store files after major 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 major compaction, and also prevent from unnecessary major compactions since the out of TTL store files will be deleted before the compaction selection.
