Java's G1 Garbage Collector

Описание к видео Java's G1 Garbage Collector

The G1 Garbage Collector, Java's default garbage collector, is a fascinating piece of technology with a long history. In this episode of Stack Walker we take a deep dive of the G1 garbage collector to understand it's key architectural features that allow it to meet its performance goals. We will also take a look at how to use G1, and a brief look into G1's future.
