Re: Drivers support for Cassandra 4.0
As a follow-up, the drivers team at DataStax has just released Java drivers 3.9.0 and 4.6.0. You can read more from the drivers mailing list links below: 3.9.0: https://groups.google.com/a/lists.datastax.com/forum/#!msg/java-driver-user/NCqlbiGp62E/nm26BmeRAwAJ 4.6.0: https://groups.google.com/a/lists.datastax.com/forum/#!msg/java-driver-user/jub63zTzOBY/R9XGoCCTAwAJ Thanks, Erik Merkle (on behalf of the drivers team) On Thu, Apr 9, 2020 at 9:30 AM Alexandre Dutra wrote: > Hi, > > The drivers team at DataStax is joining the effort towards releasing > Cassandra 4.0 by > supporting all its new features in recent driver releases.

Re: Drivers support for Cassandra 4.0
Do people think it would be a good idea to upgrade to the latest Cassandra Java Driver that is being used internally before 4.0 gets out? I created https://issues.apache.org/jira/browse/CASSANDRA-15750 for that just in case. On Fri, Apr 10, 2020 at 7:48 PM Jon Haddad wrote: > Love it - thanks for the update Alex!

Love it - thanks for the update Alex! I agree with Jordan this will be a big help with 4.0 adoption.

This is great to hear and I think will be a big benefit to 4.0 adoption. Thanks for the update! Jordan
Drivers support for Cassandra 4.0
Hi, The drivers team at DataStax is joining the effort towards releasing Cassandra 4.0 by supporting all its new features in recent driver releases. Below is an update on our status, more to come as we progress: * Python driver 3.23.0 was released on April 6th and ships with support for peers_v2 and transient replication; protocol v5 is fully implemented, with the exception of CASSANDRA-14664 (now-in-seconds) [1]. * Java drivers 3.9.0 and 4.6.0 will be released in the next few weeks. They will include support for missing features (transient replication and now-in-seconds), effectively providing complete support for protocol v5 in its current state. To make it as easy as possible for users to adopt C* 4.0, we decided to release both major branches of the Java driver, including 3.x, even if this branch is now in maintenance mode. * C# driver 3.15.0 is planned for sometime in May; it should include support for peers_v2, transient replication, and a fairly comprehensive set of protocol v5 features. * Other drivers may follow this year. Note that until CASSANDRA-14973 [2] is merged, all drivers consider protocol v5 as beta. This means that users need to explicitly allow usage of beta protocols in their drivers before they can connect with v5. Also note that CASSANDRA-15299 [3] is expected to change protocol v5 radically. Currently, drivers do not use any form of checksumming technique when connecting with v5. If anyone is able to bump that ticket in priority we will certainly appreciate it on the drivers side so we can complete the implementation. If there is anything else that we could do to help in getting Cassandra 4.0 out, please let us know.
