You can use the same procedure to restore a table from snapshot from datastax webpage

https://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_backup_snapshot_restore_t.html

Just two modifications.

after step 5, modify the name of the sstables to add the name of the table you want to copy to.

and in the step 6 copy the sstables to the right directory corresponding to the tale you want to copy to.


Be sure you have an snapshot of the table source and ignore step 4 of course

You can copy hardlinks to ALL SSTables from old to new table and then delete part of data you do not need in a new one.

If it for testing and you don’t need any specific data, just copy a set of sstables with all files of that sequence and move to target tables directory and rename it.

Restart target node or run nodetool refresh

Is there any way to copy some part of a table to another table in cassandra? A large amount of data should be copied so i don't want to fetch data to client and stream it back to cassandra using cql.
