I’m happy to announce that cqlengine is now using the Python Native Driver. For the most part, this should be a trivial upgrade. See the notes below on upgrading. The Good News Significantly less code to maintain in cqlengine itself. We no longer need to maintain connection pools, deal with fail over, dead servers, server discovery, server removal Native driver multiplexes queries over each socket, so less sockets stay open Notifications can be sent back to the client from the server.
