Alexandre Dutra commented on CASSANDRA-12142:
---------------------------------------------
I had a look to both server and driver code, also wrote some tests to validate
basic scenarios, and can confirm that both driver and server are behaving as
expected wrt the new beta flag.
I did make some minor remarks on the [driver
changes|https://github.com/datastax/java-driver/commit/ee3e855a989575f33191040e0fe991e3339b7977],
but nothing that would preclude this patch from being applied; so I'm +1.
> Add "beta" version native protocol flag
> ---------------------------------------
>
> Key: CASSANDRA-12142
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12142
> Project: Cassandra
> Issue Type: Sub-task
> Components: CQL
> Reporter: Tyler Hobbs
> Assignee: Alex Petrov
> Labels: protocolv5
>
> 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.
