Hi Shalom We are also using 5.0.4 and I can say that it's a stable version for use in production. We started switching from on-prem to k8s cassandra --> k8ssandra operator 4 years ago so the answer maybe a bit different from what you are looking for. But since you are quite familiar with it since 3.11, the general rules for Cassandra prod resources haven't changed much. 4+ cores, 24-32GB RAM with at least 16GB mem for heap Use G1GC for >16GB memory SSD + separate physical disk between commit log/data dir Turn on your audit-log (this is prod) One of the notable changes in my opinion are ZeroCoppy and SAI Index - you can look for them on the internet (Same as OS tuning setting) You can also pull some pre-configured image and digging the config - I would recommend OSS Cassandra, Datastax and k8ssandra docker repo.
