The Z Garbage Collector, also known as ZGC, is a new garbage collector optimized for low latency and very large heaps. We've developed ZGC internally at Oracle so far, but we're now open-sourcing it so as to broaden the base of both contributors and users. It was recently accepted as an official project under OpenJDK where future development will be happening.

This talk will give an overview of how ZGC works, how it scales to multi-terabyte heaps and how it maintains very low GC pause times. We'll present the goals, current status and what to expect going forward. We'll also give a quick primer on how to get started using ZGC on your workloads.
