Usage
Use this property to partition data for a class across multiple difference databases or across a database cluster such as Oracle RAC. Partitioning may provide improved scalability by allowing multiple database machines to service requests.
If multiple partitions are used to process a single transaction, use JTA (Java Transcription API) for proper XA transaction support.
