MeiK2333 commented on issue #5709: [AIRFLOW-5096] use modification time replace last loaded time, reduce database insert URL: https://github.com/apache/airflow/pull/5709#issuecomment-517644344 > I agree that this is a problem, but your change would break for dynamic DAGs (which is where a DAG .py file generates tasks based on something other than the content of the file, such as a DB query or a config file.) > > I think for your case the fix is to turn off dag pickling, by setting `donot_pickle = True` in the `[core]` section of the config. Thank you for your reply, this is indeed a proven solution, but then we lose the convenience that can be brought to us. When this option is enabled, most of the data inserted into the database is not associated with other data, and the data can no longer be read. If we can't modify Dag, can we modify the way DagPickle is generated to circumvent this problem?
