Since JDK 9, G1 GC is the default garbage collector (JEP 248). Up until 2017, Monica have shared some G1 GC details, performance tips, optimizations that help G1's adaptiveness and provided advice on manual tuning.
Since then, G1 has come a long way in improving its adaptiveness. In this session Monica will cover most of the important optimizations that are delivered from JDK9+ and how they can help your application's responsiveness, its throughput and help with footprint reduction. This is a saga that involves various regions and generations (all pun intended).
