I have one parent entity that has approx. 15000 child record(entitys). I can easily pesist quickly that one parent entity and 15000 child entity-s with batch insert, but the problem
is when I add let say add another 1000 child entitys to the parent(on the web layer), and than call entityManager.merge(parentEntity). I'm geting out od memoy exception. I'm using all-delete-orphan cusom hibernate annotation and it works well with records in DB to some 5000, but over that is a problem. Any help ?

I see what the problem is
