I found Go memory issues easier to solve than Java issues. You can see an example with etcd used in Kubernetes. I had to enable performance profiling in etcd to identify why it was eating up all the memory. It led me to a specific partition of keys that tracked back to a specific object type in Kubernetes.
It was literally enabling a flag and running some commands to do some really quick exports.
Dealing with the JVM though, heap dumps are slow to process and the UI I had to download was very clunky. I don't know if there are better tools, but even if there are the path to just doing it isn't straight forward.
