Subject [jira] [Created] (CASSANDRA-11601) Add ability to remove TTL on keyspace
Date Mon, 18 Apr 2016 23:36:25 GMT
Danyang Li created CASSANDRA-11601:
--------------------------------------

             Summary: Add ability to remove TTL on keyspace
                 Key: CASSANDRA-11601
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11601
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Danyang Li
            Priority: Minor


If tables are TTLed in your Cassandra and you try to backup the corresponding SSTable to a
new cluster, your backup will be lost automatically after a certain period of time, because
TTL are still expiring data in the backup SStable. Once the TTL elapsed, data become inaccessible
and finally will be deleted physically by compaction after GCGraceSecondes. So we cannot really
keep the backup data in a new cluster without removing these existing TTL. 

So it might be good to add ability to do batch TTL removing.
