Hi SQLAlchemy wizards. I was interested in using the new bulk operations API (http://docs.sqlalchemy.org/en/latest/orm/persistence_techniques.html#bulk-operations) but was looking for some advice based on my use case.
I have a class “FooDerived” which corresponds to a table that is linked to “FooBase” using joined table inheritance. I want to use the bulk_save_objects method to save, lets say 100,000 instances of “FooDerived”. One option would be the following: ``` session.bulk_save_objects([FooBase() for i in range(100000)]) session.flush() foo_base_models = FooBase.query.filter(/* Assume its possible to filter for the newly created objects*/).all() session.bulk_save_objects([FooDerived(id=base.id) for base in foo_base_models]) ``` Is there a better way?
