Sylvain Lebresne commented on CASSANDRA-5436:
---------------------------------------------
alright, lgtm. +1.
bq. for now perhaps it is enough to just let too new clients retry with lower
version if they get an ProtocolException on connection
Agreed. And actually, maybe for v2 of the protocol we can return some more
specific subclass of ProtocolException that includes the list of supported
versions. But let's leave that to later.

> There should be a way to version the binary protocol, CASSANDRA-5349 adds a
> message that breaks compatibility (QueryMessage) and the ticket half-handles
> versioning - it allows old clients to connect and execute queries (by always
> replying in the same version as the message sent by the client), it does not
> allow new clients to connect to old servers though.
