Replication between ObjectDB and RDBMS will enable managing the same synchronized data
in ObjectDB and in an external relational database.
This could be useful in systems that must use an RDBMS for other purposes, but need better performance for specific tasks. For systems that already use JPA - this feature might enable using ObjectDB as a performance booster, with almost no need to write new code.
