JAVA CACHE SYSTEM

The JCS goes beyond simply caching objects in memory. It provides numerous additional features: 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...
