  org.infinispan.loaders.AbstractCacheLoader

All Implemented Interfaces:

CacheLoader, CacheStore

@ThreadSafe
public class JdbmCacheStore
extends AbstractCacheStore

A persistent CacheLoader based on the JDBM project. See http://jdbm.sourceforge.net/ . Does not support transaction isolation.

Supports removal of expired entries.

It would probably be better if meta-data (expiry time) was stored independent of the value of the entry. That is, if (key,"m") == meta and (key,"v") == value.
