Shenandoah 2.0 - Advancing Garbage Collection Beyond Pause Time Control

Explore the future of Shenandoah garbage collection in this 29-minute conference talk by Christine Flood, Software Engineer at Red Hat, Inc. Dive into the implementation of Shenandoah 2.0, focusing on advancements beyond achieving pause-time goals. Learn about alternative approaches to generational GC, including partial collections of any regions, which can benefit both programs with short-lived objects and least recently used (LRU) applications like web caches. Discover how adaptive heuristics can be employed to choose regions based on previous application behavior, offering improved performance across various use cases. Gain insights into the ongoing development of Shenandoah, its integration into OpenJDK 8 and 9 in Fedora and RHEL, and Red Hat's efforts to have it accepted upstream in JDK 10.
