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.

Hi,Posted 6 months ago #
I assume you are looking at the Storage Capacity chart in OpsCenter? If so, what you are seeing is probably due to Cassandra's
auto_snapshotbehavior (configurable in
cassandra.yaml), which automatically takes a snapshot of your data before truncate or drop operations are performed.Posted 6 months ago #
