jack commented on AIRFLOW-4873:
-------------------------------
[~ash] No. there is no link between dag_id and file names.
I'm not sure I understand what you mean both dag_id and file name are static
data. they don't change nor calculated on run time. So why there isn't dag_id?
This can be taken from dag_bag isn't it? it contains a mapping of files to the
dags?
> Improve BROKEN DAG error message by specifying dag_id
