Re: [infinispan-dev] CacheStore Value Mapping

So we'd need a value mapper, which users can define, to map fields to columns. Possibly handle relationships, aggregate objects. Maybe even make things easy by providing annotations so users can just annotate their value objects. So this value mapper would effectively be reinventing JPA? ;-) Is there such a thing as JPA for Cassandra? Or an equivalent (of not specific to the JPA spec)?

For Cassandra this would have to be explicitly processed by a Value to Store mapper (which could come useful also with the plain JDBC store).
