ZGC
A low-pause garbage collector for the JVM, designed to keep GC pause times in the single-digit millisecond or sub-millisecond range. ZGC is suited for latency-sensitive large-scale online services and supports heap sizes at the terabyte scale.
Core Facts
Timeline (last 90 days)
ZGC and Shenandoah are both low-pause garbage collectors, designed with the goal of keeping GC pause times at single-digit milliseconds or even sub-millisecond levels.
Low-latency collectors such as ZGC and Shenandoah have higher memory overhead than G1GC and are not suitable for low-memory scenarios.
