You do not need a restart if you use nodetool refresh
Otherwise a rolling restart will do the trick.

You can:

3) Drop the old CF using the CLI or CQL
4) The Drop CF command will create a snapshot, you may want to delete this.
Hope that helps.

Forgot to put on the end of this, you could take that approach but it's not what CF's are designed for. Delete's are relatively cheap compared to MySql etc because most of the work is done in the compaction. My first approach would be to use row keys with prefixes, switch at the application level,
There are functions on the Cassandra API to rename and drop column families,
see
http://wiki.apache.org/cassandra/API dropping a CF does not immediately free up
the disk space, see the docs.
AFAIK the rename is not atomic across the cluster (that would require locks) so
you best bet would be t

I would suggest looking at why you do the table switch in the MySql version and consider if it's still necessary in the Cassandra version.

With more information I'd say this is not a good idea.
I would suggest looking at why you do the table switch in the MySql version and
consider if it's still necessary in the Cassandra version.
Could you use prefixes in your keys that the app knows about and switch those?

so, rename functionality is gone until
https://issues.apache.org/jira/browse/CASSANDRA-1585 is resolved?
in that case, can i also suggest removing:
rename keyspace Rename a keyspace.
rename column family
