[GitHub] [airflow] kaxil edited a comment on issue #15150: "duplicate key value violates unique constraint "dag_run_dag_id_execution_date_key" when triggering a DAG

   The DagRun table has the following constraints:
   
   https://github.com/apache/airflow/blob/83d702c345f8f4ce16d32268f4f83ee508fea676/airflow/models/dagrun.py#L96-L97
   
   which is why you can't create / trigger a DagRun that violates it i.e. you can't trigger a DAG with same `execution_date` or with same `run_id`.
