JVM Tuning post

Hey folks,

We (The Last Pickle) have helped a lot of teams with JVM tuning over the years, finally managed to write some stuff down.  We’re hoping the community finds it helpful.

Re G1GC in Java 9, yes it's the default, but we explicitly specify the
collector when we start Cassandra.

Regarding load testing, some folks like cassandra-stress, but personally I
think second to production itself, there's nothing better than an
environment running the full applications stack with simulated load.  Yes,
it's a lot of setup, but imo it's necessary for any sort of performance /
acceptance testing.

Thank you for writing this. The post is really very helpful.

One question - My understanding is GC tuning depends a lot on the
read/write workload and the data size. What will be the right way to
simulate the production workload on a non-production environment in
cassandra world.

Nice write-up. G1GC became the default garbage collection mechanism 
beginning in Java 9, right?

Many thanks to "The Last Pickle", also for TWCS advice's. Especially for
C* new features on version 3.11.1
