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 via HTTP, TCP, or UDP
• UDP Discovery of other caches
• Element event handling
