Right now, I have the following:
Does Simperium support this kind of relationship?
EDIT: I guess I'm wondering if relating entities in this way would impact performance. Thanks!
Though there isn't a unit test for this, it should be fine. The handling of self-referential relationships shouldn't be any different than the handling of one-to-many relationships between two different Entities. For example, Simperium will resolve relationships if they sync out-of-order.
Behind the scenes, it's just unique IDs that Simperium is tracking and syncing.
