Is there a potential issue when restoring in parallel?

I notice for example it fails to re-create some mat views I have in schema B as they query from some table in schema A that hasn't been created yet at that moment.

It tracks dependencies at the per-object level.  I'm not aware of any
way that a schema as such could depend on another, but it should take
care of correct restoration order for the objects within them.
