------------------------------------------
Summary: Snapshots for dropped column families management
Key: CASSANDRA-6280
URL: https://issues.apache.org/jira/browse/CASSANDRA-6280
Project: Cassandra
Issue Type: New Feature
Components: Core
Reporter: Stephen Johnson
Priority: Minor
Currently the only option for removing snapshots of dropped column families is
to delete them manually from the file system. We have a user that creates
column families dynamically and deletes them when they are no longer needed.
The result is snapshots of these tables build up quickly and disk space can
only be reclaimed when they are manually deleted.
A potential solution for this might be to add a flag to the nodetool
clearsnaphot command that removes snapshots that no longer exist in the
keyspace because they have been dropped.
Another possibility might be to add a flag on cql delete query that ignores the
auto_snapshot in the cassandra.yaml and does not create a snapshot for the
deleted column family or keyspace.
