The G1 Garbage Collector. The Garbage-First (G1) collector is a server-style garbage collector, targeted for multi-processor machines with large memories. It meets garbage collection (GC) pause time goals with a high probability, while achieving high throughput. The G1 garbage collector is fully supported in Oracle JDK 7 update 4 and later releases. The G1 collector is designed for applications that:, G1 opportunistically tries to reclaim humongous objects if they are not referenced by many objects at any kind of garbage collection pause. This behavior is enabled by default but you can disable it with the option -XX:G1EagerReclaimHumongousObjects. Allocations of humongous objects may cause garbage collection pauses to occur prematurely.
11/17/2020 · Note: The instructions in this document are applicable for Edge Private Cloud users only. This document explains how to enable Garbage First Garbage Collector (G1GC) on the Apigee Edge’s Message Processors. Apigee Edge’s Message Processor runs on Java Virtual Machine (JVM) and uses the default Garbage Collector—serial or parallel depending on the hardware and operating system.
In between the CMS and GC Logging sections, there should be one more section in that file- the G1 section, which looks like this: ### G1 Settings (experimental, comment previous section and uncomment section below to enable ) ## Use the Hotspot garbage-first collector.

G1 is a generational, incremental, parallel, mostly concurrent, stop-the-world, and evacuating garbage collector which monitors pause-time goals in each of the stop-the-world pauses. Similar to other collectors, G1 splits the heap into (virtual) young and old generations.
G1 GC tries to maintain a balance between throughput and latency. It was introduced in Java 7 u4 and made default in Java versions [9; 13]. It might be suitable for applications that run on multiprocessor machines with a large amount of memory. It meets Garbage Collection pause-time goals with high probability while achieving high throughput.
