Event parameter is used to pass model_name argument. See the top of the page for the Lambda update procedure. Parameters ---------- event : dict A dictionary containing metadata regarding the triggering event. In this case the dictionary contains model name. context : object This is an object containing potentially useful context provided by Lambda. See the documentation cited above for details.
