Hazelcast Jet on Generational ZGC

Posted on November 7, 2023

A few years ago the developers of Hazelcast Jet decided to try out the different GC alternatives available at the time. The result was this blog-series from 2020 and the results for ZGC looked very promising. Three years have passed since then and a lot more work has gone into ZGC. It became production ready in JDK 15, concurrent stack scanning was added in JDK 16 and now, in JDK 21, generational support has been added making it even more suitable for low latency workloads. In this post we look at one of the Hazelcast Jet experiments and see how Generational ZGC performs.
