[jira] [Created] (CASSANDRA-16451) Add ability to ttl snapshots

Paulo Motta created CASSANDRA-16451:
---------------------------------------

             Summary: Add ability to ttl snapshots
                 Key: CASSANDRA-16451
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16451
             Project: Cassandra
          Issue Type: Improvement
          Components: Tool/nodetool
            Reporter: Paulo Motta


It should be possible to add a TTL to snapshots, after which it automatically cleans itself up.

This will be useful together with the {{auto_snapshot}} option, where you want to keep an emergency snapshot in case of accidental drop or truncation but automatically remove it after a specified period when it's no longer useful. So in addition to allowing a user to specify a snapshot ttl on {{nodetool snapshot}} we should have a {{auto_snapshot_ttl}} option that allows a user to set a ttl for automatic snaphots on drop/truncate.
