Explore the Z Garbage Collector (ZGC), a cutting-edge JDK garbage collector designed for low latency and high scalability, in this 37-minute conference talk by Erik Österlund from Oracle. Discover how ZGC achieves over 36% higher throughput than existing JDK collectors while maintaining a maximum pause time of two milliseconds. Learn about ZGC's single-generation, concurrent design, and its innovative use of load barriers. Delve into performance metrics, logging capabilities, and detailed statistics. Gain insights into future plans for ZGC, including generational collection. Understand how to implement and optimize ZGC for latency-sensitive applications, and stay informed about ongoing developments through mailing lists and bleeding-edge updates.
