      Description

      Currently, if you run upgradesstables, cassandra will run through every single SSTable within the scope of the request. Where we have some large tables, an upgrade on a single sstable can take hours, even if its already sat on the same version.

      After upgrading to a new cassandra version, it would be ideal to be able to upgrade only sstables not sat in the latest version, as it seems like it just needs to do a massive amount of disk IO, with nothing being achieved at the end of it.

      Maybe its worth putting an option onto the nodetool command, or creating a new command for this type of upgrade
