Hi Moacir, we worked on the same problem recently and have a moderately working solution, but it involved a patch to DataNucleus itself.
This is how an entity is annotated: @PersistenceCapable(identityType = IdentityType.DATASTORE, schema = "subscription_service", table = "subscribers") @Extension(vendorName = "datanucleus", key = "datastore", value = "store-subscription") ... public class Subscriber ... Note the 'datastore' key with value 'store-subscription'. Matching to that value, we have this in persistor_datanucleus.properties: isis.persistor.datanucleus.impl.datanucleus.datastore.store-subscription=persistor_subscription.properties and finally the file persistor_subscription.properties which contains the usual: javax.jdo.option.ConnectionDriverName=com.mysql.jdbc.Driver javax.jdo.option.ConnectionURL=jdbc:mysql://localhost:3306/subscription_service javax.jdo.option.ConnectionUserName=root javax.jdo.option.ConnectionPassword=tiger This is the branch containing the commit which we have tested with datanucleus-core-4.1.2 and 4.1.7: https://github.com/m-creations/datanucleus-core/commits/mcreations-federatedstoremanager If you are interested in trying it out and don't want to build datanucleus-core yourself, I could release a patched 4.1.7 version which is compatible with Isis 1.12.1.
