I can retry Java 11.

I am seeing this error a lot - still debugging, but I'll throw it outthere - using 4.11.1 driver and a 4 node RC1 cluster. I'm seeingwarning in the cassandra logs about slow queries, but no errors. Thiserror is client side.

Cassandra 4.0 should work fine with java 11, including zgc (though zgcin jdk11 isn't meant to be production ready).�


The things I care most about:

- Much faster streaming, which you care about if you're not usingEBS/Disaggregated storage- Virtual tables that make observability much more consistent (lessJMX, more CQL)

- Incremental repair finally actually works (correctly)

- There's a bunch of new defensive rate limiters and hot-tunableproperties in the database that people will enjoy once they need touse them

- JDK11�

    Hi Sean - I'm using RC1 now in a research environment on bare
    metal.  The biggest drawback of Cassandra for me is that
    Cassandra has issues working with modern large servers - a server
    with >32TBytes of SSD seems to be a non-starter.

    I tried running Cassandra with java 11, and that doesn't appear to
    work.

There is not enough 4.0 chatter here. What feature or fix of the

What is working well so far? What needs more work? Is there
anything that needs more explanation?
