------------------------------------------
Summary: Add command to reclaim disk space for dropped column
families
Key: CASSANDRA-7127
URL: https://issues.apache.org/jira/browse/CASSANDRA-7127
Project: Cassandra
Issue Type: New Feature
Components: Core
Reporter: Bogdan Batranut
Priority: Trivial
Fix For: 2.1 beta2
I found out that after a DROP a column family's data is not deleted. I looked
into the /data/keyspace dir and saw dirs corresponding to old columnfamilies
that I have dropped in the past. I do see the benefit of taking snapshots when
dropping but I can also see the need to reclaim disk space. During developent
on a cluster that will be in production, people might push a lot of data into a
columnfamily and change the definition for some reason. The old unused data
will eat a lot of space.
So can you please implement a feature that will reclaim badly used disk space?
Thank you.
