Hi,
we have already talked in chat but I will answer here as well for others.
At the moment, it’s not possible to do this with the Bolt or Http protocol (it should work with embedded).
The reason is that JPA does not have any similar concept for associations.
The only thing you can do is to use native queries. In this case Hibernate OGM will return the object the same way the underlying client is returning it. For example, if you are using Bolt, it will return an InternalRelationship.
We have an open issue for proposing better ways to deal with relationships: https://hibernate.atlassian.net/browse/OGM-920
It doesn’t cover exactly your use case but maybe you can leave a comment and describe what you need so that when we will work on the feature we will keep that in mind.
Thanks,
Davide
