Java Caching System – distributed caching system

Java Caching System (JCS) is a distributed caching system written in Java.

This software is designed to speed up applications by providing a means to manage cached data of various dynamic natures. It uses a combination of memory, disk, lateral, and remote components to provide data integrity and session failover across webservers.

JCS is part of the Jakarta Project, an umbrella project from the Apache Software Foundation.

Features include:

  • Caching objects in memory.
  • Memory management.
  • Disk overflow (and defragmentation).
  • Thread pool controls.
  • Element grouping.
  • Minimal dependencies.
  • Quick nested categorical removal.
  • Data expiration (idle time and max life).
  • Extensible framework.
  • Fully configurable runtime parameters.
  • Region data separation and configuration.
  • Fine grained element configuration options.
  • Remote synchronization.
  • Remote store recovery.
  • Non-blocking “zombie” (balking facade) pattern.
  • Lateral distribution of elements via HTTP, TCP, or UDP.
  • UDP Discovery of other caches.
  • Element event handling.
  • Remote server chaining (or clustering) and failover.
  • Custom event logging hooks.
  • Custom event queue injection.
  • Custom object serializer injection.
  • Key pattern matching retrieval.
  • Network efficient multi-key retrieval.
  • Rich grouping mechanism, where groups of elements can be invalidated and whose attributes can be listed.
  • Twice as fast as Ehcache.
