About NoSQL Persistence Units

NoSQL persistence units are configured the same as JPA persistence units. The persistence.xml file is used to define the persistence unit. NoSQL persistence units can be application managed, JTA managed, injected, or created through Persistence the same as regular JPA persistence units. NoSQL persistence units do have some specific persistence unit properties that are required, and have some limitations.

NoSQL defines the following persistence unit properties:

Persistence Unit Properties for NoSQL Platforms

To use a NoSQL platform you must set both the eclipselink.nosql.connection-spec to the connection spec class name and the eclipselink.target-database to the platform class name. Each NoSQL platform also supports platform-specific properties that can be set using eclipselink.nosql.property. For more information on values for MongoDB, Oracle NoSQL, XML, JMS, and Oracle AQ, see "@NoSql" in Java Persistence API (JPA) Extensions Reference for EclipseLink.
