Class FeatureStoreCacheProxy

java.lang.Object

org.ff4j.cache.FeatureStoreCacheProxy

All Implemented Interfaces:

FeatureStore

public class FeatureStoreCacheProxy
extends Object
implements FeatureStore

Access to FeatureStore could generate some overhead and decrease performances. This is the reason why cache is provided though proxies. As applications are distributed, the cache itself could be distributed. The default implement is InMemoryFeatureStoreCacheProxy but other are provided to use distributed cache system as redis or memcached.
