dstandish edited a comment on issue #5263: [AIRFLOW-4490] dag_run.conf should be an empty dictionary by default instead of None URL: https://github.com/apache/airflow/pull/5263#issuecomment-491671014 > Is there ever a case where the DagRun is not committed to that database immediately? Intuitively, it seems likely impossible in actual execution. But if you are experimenting in interactive console, as you have demonstrated, it is certainly possible. (And I do that sometimes when working out template behavior.) Another alternative approach to this would be to leave default value alone, but just add a `get_conf` method on `DagRun`, just like there is now with `get_dag`. `get_conf` could return an empty dict if there is no conf. We could also add a `dag_run_conf` to `TaskInstance`, which would also handle the case when there is no `dag_run`.
