    PostProcessing stage of the transformation (if using ParantID and ElementID) should use paging (or another approach) for a better performance, it should also be better logged and display number of objects processed, a number of objects in the list and paging statistics. It should also have a retry logic in order to avoid losing transformation results in case of AF Timeouts.
