Annotation Type Partitioned

@Target(value={TYPE,METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface Partitioned

Partitioning is used to partition the data for a class across multiple difference databases or across a database cluster such as Oracle RAC. Partitioning can provide improved scalability by allowing multiple database machines to service requests. This annotation configures the named partitioning policy to be used for this Entity or relationship.

Partitioning can be enabled on an Entity, relationship, query, or session/persistence unit.
