   @hussein-awala - I am afraid @ashb is right. DagFileProcessor executes more stuff. It performs sla management, also when DagFileProcessorProcess gets started it receives callbacks to execute for that particular file. Those are the callbacks that are generated elsewhere (allways when callbacks cannot be executed within the process that generates the callback for whatever reason) and stored in the database. Then whenever DagFileProcessor processes a given file, it will execute the callbacks.
   
   So the idea that you can stop DagFileProcessor and run it "when needed" is not good as @ashb mentioned.  Unless we introduce some other entity that can process those callbacks of course.
