I haven't used hibernate personally, but I never heard anything like that. So please elaborate. Where did you get that information? Also what do you mean with "graph"? The graph of associated objects that are updated by one hibernate call, or is your data actually graph data? If so, how is that mapped? do you have any self-referential associations? Is it really stack that you are talking about?
