Hi Shalom, Yes, 5.0.4 is production ready. On OS level it makes sense to start from https://docs.datastax.com/en/dse/6.9/managing/configure/recommended-settings.html#configSetKernelParameters
JDK: latest JDK17 build, if you are looking for low latency you can try to use Shenandoah or ZGC instead of G1 but they can be more sensitive to overload/load spikes Cassandra yaml: to get the best performance by using the latest features (such as trie memtables, direct IO commit log, etc) create your cassandra.yaml from cassandra_latest.yaml configuration. The default logback configuration is ok from perf point of view.
