NHibernate 'Write Only' collection, if there is such a thing?

Question

Does anyone know if it's possible to add an item to a collection without actually retrieving the persisted items in that collection? Is there a mapping that will allow me to achieve this?

I have a scenario where I'm performing some batch processing on some customer objects. I want to add some notes to my customers as I go but don't want/need the already persisted notes for that customer as it's a background process and simply adds to the collection.

Answer 1

18.5.3. Bags and lists are the most efficient inverse collections

In any case, you can skip the collection completely and just use a many-to-one (i.e. set Note.Customer instead of adding a Note to Customer.Notes)

Answer 2

I'm not sure about your original question, but I can offer a workaround- create a new Note object, set its Customer property to the wanted customer, and persist it. simple, and works well for me.
