Hi all,
We're moving from an existing C# application on SQL server to a Java and Spring service tier with the Cassandra storage back end. I haven't used Hibernate in java in a production environment since version 3 was released, however I have played around with the JPA on some small projects. Is it possible to use a minimal Hibernate configuration and implement a custom api for serialisation and querying to store and retrieve values in Cassandra? If this isn't possible with Hibernate, is DataNucleus my best bet for a JPA provider that will meet the requirements of basic object persistence and mapping?

Thanks,
Todd
