qStudio allows loading your own .jar file with JDBC drivers: https://www.timestored.com/pulse/help/connections-custom-jdb... In theory Cassandra has a JDBC driver: https://github.com/ing-bank/cassandra-jdbc-wrapper It's not pretty and not seamless but it should work and if it doesn't and I can fix it, I'm happy to help.

I created a Custom JDBC Server connection, but I can't figure out how to specify the driver file. Clicking the Test button offers to download one, but fails with an IndexOutOfBoundsException. I don't see anything relevant in the Settings, and I don't see anything resembling the DBeaver driver manager.

I don't know how to translate that Pulse FAQ to qStudio. FWIW, I'm using Java 11 on macOS 14. I have a single qstudio.jar file.

What JDBC driver are you trying? I can try it tomorrow possibly even on mac.
