(Sorry if I missed a pre-existing ticket for this.)
There is an IMO big caveat of bulk_create(): It does not set primary key of objects it creates.
In my current project, using bulk_create would improve performance, but as I often need an id of the newly created objects, I have to save them one by one.
I think it would be perfect if bulk_create starts to set the primary keys of the objects in the given sequence. At least postgresql supports it ("RETURNING id" clause gives us a set of id's).
