----------------------------------------
I created a tool to do batch TTL removing. If any interest.
> Add ability to remove TTL on table
> ----------------------------------

> Key: CASSANDRA-11601
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11601
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Danyang Li
> Priority: Minor
> Fix For: 2.2.x
>
>
> 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.
