Upgrade of Cassandra driver in connector

[Thms Hmm]

Hey,

are there any plans to upgrade the version of the Cassandra driver to a newer one?

Currently the driver v3.0 is integrated which dates back to 2016 and we are having problems getting this working with AD authentication and Cassandra V4.x.

Also the shading makes it not possible to easily exchange the driver. Is that correct?

Thanks for your help.

Kind regards

Thomas

There is this Jira issue, along with a PR:
https://issues.apache.org/jira/browse/FLINK-8424. But no-one has worked
on it for a while. There were some difficulties in getting it to work
even with that "minor" update. I'd be very happy if someone with more
Cassandra experience would pick up this issue.

Yes, the shading makes it impossible to exchange the driver, I'd say.

Best,

Just for info the Cassandra client version 4 driver does not leak
guava anymore, but represents a considerable API change so maybe worth
to explore that as an alternative to 'modernize' the connector.

Hi Aljoscha and Ismaël,

thanks for your fast reply and sorry for my late reply. I'll keep an eye on the pull request. If I find the time I will try to get the connector running with v4 by myself. Are there any ideas out there regarding modernization or did you just mention it because of the changes the new driver introduces?
