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?

有帮助吗？

解决方案

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

其他提示

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.
