If so, what you are seeing is probably due to Cassandra's <code>auto_snapshot</code> behavior (configurable in <code>cassandra.yaml</code>), which automatically takes a snapshot of your data before truncate or drop operations are performed. </p> http://www.datastax.com/support-forums/topic/column-family-remove-error#post-7470 Mon, 12 Nov 2012 15:13:36 +0000 ctetik 7470@http://www.datastax.com/support-forums/ <p>Hi,<br /> I am a newbie in cassandra and opscenter. I inserted about 8 gb data into a column family. Then, I removed it from cassandra by using opscenter. It is removed but the 8 gb data still in the storage. Then, I deleted keyspace but nothing changed. Do you know the reason is because of opscenter, or cassandra or there is something I don't know? I will be appreciated if anybody can help me. </p>
