Restore Cassandra snapshot to new keyspace in same cluster

Question

I've found documentation on restoring a keyspace snapshot to the same keyspace and also restoring it to a new cluster. However, I'm trying to make a copy of a keyspace in Cassandra and cannot find how to restore a snapshot to a new keyspace. Does anyone know if this is possible or have other recommendations on how to make a copy of the keyspace?

Answer 1

Step 1: In your new keyspace, redefine the column families the same way as they were defined in the old keyspace. You can get the list of commands by running this cql:

DESCRIBE KEYSPACE ;

Note that here, your keyspace replication factor, etc shall remain the same.

Step 2 (do this on each node): Under the old keyspace folder inside Cassandra data directory, there should be a snapshot folder per ColumnFamily. Copy the SSTables directly from the snapshot folders to the relevant ColumnFamily folders of the new keyspace inside Cassandra directory.

Step 3: Do a rolling restart, and run repair on each node.
