Epsilon is a no-op garbage collector. JEP 318 explains that "[Epsilon] … handles memory allocation but does not implement any actual memory reclamation mechanism. Once the available Java heap is...

...garbage collector and tweaking its settings to achieve the smallest impact for a given workload. The Epsilon team foresaw that under certain situations that are especially sensitive to latency...

Java 11 introduced the Epsilon GC garbage collector, or as it's also known, the 'no garbage collection collector.' Basically, this GC algorithm never cleans...

Providing a garbage collector that does not in fact do garbage collection may be seen as the dangerous practice. Accidentally enabling Epsilon GC in production may lead to surprise JVM failures...

Epsilon is the "no-op" garbage collector. Java 12 adds the Shenandoah Garbage Collector. Like ZGC, it manages large heaps with short pause times but uses a very different approach.

JEP 318: "Epsilon: A No-Op Garbage Collector (Experimental)" was introduced in OpenJDK 11. The goal for that implementation is to provide the minimal implementation that can be used when memory...

Also for extremely efficient programs that don't create garbage then not having a garbage collector is useful, also for very short lived programs.

The Epsilon garbage collector only allocates memory. It cannot release any allocated memory, so the application is very likely to crash because of an OutOfMemoryError.

The garbage collector, or just collector, attempts to reclaim garbage or memory occupied by excluding Epsilon GC, the smallest footprint belongs to Serial GC, followed by CMS GC, ZGC...

The parallel garbage collector is also called as a throughput collector. Unlike the serial garbage Epsilon is a non-operational or a passive garbage collector. It allocates the memory for the...

The Epsilon project could benefit testers, but it wouldn't bring manual memory management to Java.

This collector is aimed at aiding JVM implementers and researchers and, to a lesser extent but Epsilon GC can serve as the control variable to measure the performance of other garbage collectors.

Java might get a new garbage collector that can be the best for performance testing. Named Epsilon GC, the project proposal is aimed at delivering lowest runtime performance overhead possible by...

JEP 304: Garbage Collector Interface. Introducing an interface for garbage collectors will Before Java10, the garbage collector code was fragmented in places scattered all over the HotSpot sources.

Speaking of garbage collectors, I had a thought the other day, wondering if performance could > There is a strong temptation to use Epsilon on deployed programs, rather than to confine it to...

In computer science, garbage collection (GC) is a form of automatic memory management. The garbage collector, or just collector, attempts to reclaim garbage, or memory occupied by objects that are no longer in use by the program.
