-----------------------------------------

             Summary: Compatibility mode for 2.1
                 Key: CASSANDRA-6570
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6570
             Project: Cassandra
          Issue Type: Task
          Components: Core
            Reporter: Jonathan Ellis
            Assignee: Marcus Eriksson
             Fix For: 2.1


Upgrading to a new major Cassandra release is a big commitment, because once on a new version
you can't downgrade again because we write new-version sstables.

Let's add an option to write old-version sstables so that users can try upgrading a single
2.1 RC node in a 2.0 cluster with the safety net of being able to back it out if anything
goes wrong.
