   Even if we set 1min_ttl, 5min_ttl, 2hr_ttl to 1 day, the OpsCenter's KeySpace (SStables) has been increasing.

   [Question]
   Would you let me know how to limit the OpsCenter's KeySpace size?

   Thanks.

   Is compaction occurring normally for the OpsCenter keyspace? Data that is expired with a ttl will only be actually deleted from disk once compaction occurs.

   Also, when you say the size is increasing do you mean the live size of the column families reported by cassandra or the on disk size reported on the machine. If you are referring to the size reported by machine can you verify it matches the live size reported by cassandra? This information is available in 'nodetool cfstats' or in the OpsCenter performance graphs (metric data for the OpsCenter keyspace is turned off by default though).
