ReplicationPartitioning sends requests to a set of connection pools. It is for replicating data across a cluster of database machines. Only modification queries are replicated.

Partitioning can be enabled on an Entity, relationship, query, or session/persistence unit. Partition policies are globally named to allow reuse, the partitioning policy must also be set using the @Partitioned annotation to be used.
