Hi, I noticed that you mentioned your goal is to optimize write throughput, and that you're using
Cassandra 3.11.2.Optimizing for write throughput is usually a proxy for optimizing for compaction, as
the cost of writes are very cheap but compacting to keep up with it can be pretty expensive.You'
G1GC would be the most suitable option and it has better control over
pauses and optimal.

CMS has a higher risk of a long stop-the-world full GC that will cause a
burst of timeouts, but if you're not getting that or don't mind if it
happens now and then CMS is probably the way to go. It's generally
lower-overhead than G1. If you really don't care about latency it might
even be worth
Thank You
I'm going to achieve the most possible (write) throughput with Cassandra and
care less about latency, recommendations from community suggests that better to
use G1GC with 16GB heap, but when i already got 92% throughput with CMS, should
i consider changing it?
