Sylvain Lebresne commented on CASSANDRA-3990:
---------------------------------------------
bq. Meaning there will be C* versions which support both?
No. But it is possible even for the same user to have a cluster with mixed C*
versions. And yes 3.1.0 will be backward compatible with 3.0.0. But 3.1.0 may
have feature that doesn't work with 3.0.0. So if someone wants to use 3.1.0
explicitly, he ought to be able to say so (and if the C* server is an old one
that only know about 3.0.0, it will refuse the connection).
It is true that you would be safe to always set the version to 3.0.0, even when
the server will be on 3.1.0, but what I mean is that the server does some fine
grained version check, so if we don't expose the ability to choose which
version of CQL exactly we want, we loose a bit of flexibility. We may consider
that fine for cqlsh though, I don't know.
