Question

How to rename keyspace and columnfamily in cassandra 1.2? I know that cassandra-cli rename api is no longer supported - How to rename keyspace in Cassandra. Maybe there are some api in CQL3? Or some api for creating new columnfamily and coping all data from old to new columnfamily?

Était-ce utile?

La solution

Renaming is disabled internally, not just within the thrift API. So there isn't a CQL command to do it either.

However, there is a manual process which is described here:

https://issues.apache.org/jira/browse/CASSANDRA-1585

Autres conseils

For rename only a column family also you can follow the next instructions:

Basically is create the new CF, copy the SStables from the old column family to the one renaming the files.
