Description

There is currently no way to pass JPA or EclipseLink specific connection/DataSource properties in from ambari.properties. Although there exists Configuration.getDatabaseCustomProperties, these are actually driver specific properties and not properties for EclipseLink.

For example, if I wanted to pass in to the JDBC Driver foo=bar, then I could set
server.jdbc.properties.foo=bar and this will get translated into eclipselink.jdbc.property.foo=bar.

However, if I wanted to set any of the EclipseLink or JPA specific DataSource properties (see http://www.eclipse.org/eclipselink/api/2.6/org/eclipse/persistence/config/PersistenceUnitProperties.html) I would not be able to.

Proposal is to add something similar to the custom driver properties:

server.persistence.properties.eclipselink.jdbc.batch-writing.size=25

Which could get translated into

properties.put("eclipselink.jdbc.batch-writing.size", 25)
