Hibernate - How to persist a new item in a Collection without loading the entire Collection

Question

I have a collection in my model that contains a set of \'previous versions\' of my root domain object. The previous versions are therefore \'immutable\' and we will never wa

If I understand well your need:

• you have an in-memory add-only collection of immutable objects
• how to add an item to that collection without initializing the entire collection (in the current Session)?

Did you consider maintaining your collection disconnected?

• Load it once when the application starts
• Adding an element would mean two operations, done by a single service in only one place:
  • save the element (fast database operation, no cascading is done to the parent)
  • add the element to the existing disconnected collection (no database operation)
