ASF GitHub Bot commented on AIRFLOW-3702: ----------------------------------------- damnko commented on pull request #4676: URL: https://github.com/apache/airflow/pull/4676#issuecomment-633459678 Hi, can the `run_backwards` parameter be used when defining a DAG like so? ```python from airflow import DAG dag = DAG( dag_id = "..." scheduled_interval = "@daily" run_backwards = True ) ``` It seems to be something that can be used only manually through the Airflow cli but wanted to confirm. Is there any way to setup a DAG to run as backfilling job from the most recent DAG to the oldest?
