How to set AncestorKey to Entity when writing to Datastore from Apache Beam in Java?

I'd like to store two kinds of entities linked by a composition.
A User have multiple Order but I don't know how to set the relationship such as explained in the doc for AppEngine.
Key.Builder keyBuilder = DatastoreHelper.makeKey(kind, new String(order.getOrderId()));
Entity.Builder entityBuilder = Entity.newBuilder();
entityBuilder.setKey(keyBuilder);
entityBuilder.putProperties("order_id", DatastoreHelper.makeValue(order.getOrderId()).build());
entityBuilder.putProperties("user_id", DatastoreHelper.makeValue(order.getUserId()).build());
return entityBuilder.build();
I'd like to use a function like setAncestor() or addAncestor() any hints ?

The ancestor relationship is on the key of the entity not the entity itself. So you can either pass the parent key to DatastoreHelper.makeKey or use addAncestors on the key builder like you referenced in the doc for App Engine
