Design Specification: Support SessionBroker in JPA
|2010/10/22||Andrei Ilitchev||Initial Version|
The goal is to allow for different classes contained in a single persistence context to be mapped to different databases.
em.persist(new A(..)); em.persist(new B(..)); // insert A into db1; insert B into db2: // the two different data bases possibly from different vendors em.flush();
The two main use cases:
- Unify multiple persistence units (with independent from each other object models).
- Split single persistent unit.
