Yeah, I was afraid of the relations part. In the use case I'm
dealing with, there are no relations, but maybe the JDO layer can't
infer that. For now I won't worry about it. If it turns out the
fetches related to these deletes are a bottleneck, I will use the low
level API.
Is there a way to delete an entity without having to fetch it from the
datastore first?

since these can cause cascade of operations, it typically has to be
loaded into memory first. The only situation where it wouldn't need to

You can use DatastoreService.delete(Key...)
