Dynamic configuration of EntityManagerFactory
---------------------------------------------
Key: OPENJPA-305
URL: https://issues.apache.org/jira/browse/OPENJPA-305
Project: OpenJPA
Issue Type: New Feature
Reporter: Pinaki Poddar
OpenJPA configures EntityManagerFactory at creation time via an instance of
Configuartion object. Once EntityManagerFactory is created and a EntityManager
is issued from it -- the Configuration is frozen by design. That is no further
changes to Configuration is allowed as long as EntityManagerFactory lives.
For certain configuration properties, it is desirable to change them during the
lifetime of a EntityManagerFactory.
This issue is raised to initiate a discussion on such a feature, the
possibility and limitations of dynamic update and track the impact of such a
change as frozen Configuration is an important assumption.
