Hazelcast offers an L2 cache for Hibernate as documented in their manual here: http://hazelcast.com/docs/2.1/manual/single_html/#HibernateSecondLevelCache.
My question is if there is the same for EclipseLink? (I'm thinking not but maybe someone knows if there are plans for it, etc.)
Answer is no, but they are open to contributions since it's open source.
