Subject [jira] [Resolved] (CASSANDRA-11601) Add ability to remove TTL on table
Date Tue, 19 Apr 2016 08:55:25 GMT


Sylvain Lebresne resolved CASSANDRA-11601.
    Resolution: Duplicate

We can't efficiently remove all the TTL on a table, and besides, it seems what you want is
to basically do this on your backup and the simplest way to do this is probably CASSANDRA-7471
so marking this as a duplicate.

> 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.
