Hi all,

I want to merge one keyspace (A= ) data into another (B) with exactly same scheme. The partition keys of all= records are unique in both keyspaces. Can I just copy all files under keys= pace A column families into keyspace B column families folders, after runni= ng nodetool flush? Is filenames collision possible?

Thanks,
