Simplest definition would be to persist some classes to a secondary datastore. For example

@PersistenceCapable
@Extension(vendorName="datanucleus", key="datastore", value="ds2")
public class MyClass

so all instances of MyClass are persisted to datastore "ds2", where this name is defined in a persistence property
datanucleus.datastore.ds2={props_file_name_for_this_datastore}
