--------------------------------------
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.
