I assume you must have but feel compelled to check - did you experiment with the new low-latency Java garbage collection options? Feels like this is exactly the sort of case they would be catering for.
- jhgg 4y agoWe did with some. Although I don't recall the exact specifics but there were improvements we were able to make with GC tuning and switching from CMS to G1. We were on old version of Cassandra for our most problematic cluster - and it was our last cluster to migrate to Scylla so we didn't really do much to explore the problem space of JVM tuning when we were already moving away from JVM already.
- xxs 4y agoJust for reference G1 is 15y old.

- zmmmmm 4y agothanks, good to know! If you had fully explored using those and found them insufficient then it would have been an interesting case study in them "not working". Supposedly this is a nearly "solved problem" but I am very curious to hear real world use cases and whether it truly works or not.
