Chapter 14. Cache Managers

14.1. About Cache Managers

A Cache Manager is the primary mechanism used to retrieve a cache instance in JBoss Data Grid, and can be used as a starting point for using the cache.
Cache Managers are resource intensive and therefore a single cache manager for each Java Virtual Machine (JVM) is recommended unless a specific configuration requires multiple cache managers.
In JBoss Data Grid, a cache manager is useful because:
  • it can create multiple cache instances on demand using a provided standard.
  • it retrieves existing cache instanced (i.e. caches that have already been created).
