Should I design the import process by creating hundreds of ProductPersistentActor (for each product in the CSV file) and keep a state (and after a while destroy them all)? Will that fit the actor model?
I really don't want to do any ETL process for this. The importing process should go through the domain model which does validation. If a product that is read from the CSV file fails the validation it wont be imported. The validation happens in the domain model.
