             Summary: Add "beta" version native protocol flag
                 Key: CASSANDRA-12142
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12142
             Project: Cassandra
          Issue Type: Improvement
          Components: CQL
            Reporter: Tyler Hobbs


As discussed in CASSANDRA-10786, we'd like to add a new flag to the native protocol to allow drivers to connect using a "beta" native protocol version.  This would be used for native protocol versions that are still in development and may not have all of the final features.  Without the "beta" flag, drivers will be prevented from using the protocol version.

This is primarily useful for driver authors to start work against a new protocol version when the work on that spans multiple releases.  Users would not generally be expected to utilize this flag, although it could potentially be used to offer early feedback on new protocol features.

It seems like the {{STARTUP}} message body is the best place for the new beta flag.  We may also considering adding protocol information to the {{SUPPORTED}} message as well.
