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

Thanks that's very helpful. I'm assuming there's no requirement to stop
or restart Cassandra?
Thanks,

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.

How can I rename a column family (if version matters, I'm interested in
both 0.8.x and 1.0.x).
Thanks,
Jim
Renames are not yet supported (see
https://issues.apache.org/jira/browse/CASSANDRA-1585)

Hello,
I would like to rename some column families but I discovered that the
system_rename_column_family disappeared in 0.7. How to rename the column
family now? I tried system_update_column_family method but it doesn't work
for renaming :(
Thank you!
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?

Hi,
In Mysql I do this pattern and wonder if I could do something similar
with cassandra.
1. Live/Production queries always coming into LiveTable
2. Build new data with BuildTable
3.RENAME TABLE LiveTable TO OldTable, BuildTable To LiveTable
4. DROP TABLE OldTable, Goto step #2 build
o suggest removing:

sorry for the empty body... i hit send a bit prematurely.
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
