Garbage Collection pauses make it hard for Java applications to meet quality of service guarantees. No matter how fast your application processes requests, a 30 second GC pause is going to ruin any guarantees you might want to make.

Shenandoah is a new GC algorithm designed to address this issue. We take a simple approach that allows us to do more work while your Java program is running so we can substantially reduce the time the JVM is paused. Our goal is to be able to garbage collect 100gb+ heaps in under 10ms.

This talk will focus on the current status of the project, the goals we've met so far, and what we are hoping to achieve in the coming year. We might even share some performance numbers.
