Auto-persistence of associations with null ids would be beneficial (for users & ArangoDB)

[haqer1]

For instance, for the
https://github.com/arangodb/spring-data#reference
example, when address.id is null, it's not currently auto-persisted; thus it currently has to be persisted separately (prior to persisting the parent entity). In JPA implementations i've worked with, the association(s) would be auto-persisted (allowing to persist an entire aggregate[1] by making only 1 call to persist the aggregate root).

I think it would be beneficial (for users & ArangoDB) if arangodb/spring-data functioned similarly: it would make development easier, & facilitate adoption of ArangoDB. The implementation also shouldn't be difficult...
