Hi, While I still wonder about why detaching my entities doesn't reduce my heap memory usage, I also wonder whether there is a possibility for a query to return detached objects in the first place? This might be quite efficient for scenarios where you need to read lots of data but not update it or need any other features of a managed entity. Calling detach() for every object looks to be rather expensive, and above method would not only avoid that but could possibly avoid some attachment overhead aswell. ___________________________________________________
