I haven't been able to reproduce this issue outside of our production environment, but after a little more investigation I think that our issue is related to https://github.com/apache/airflow/pull/13278#issuecomment-755218560. Here's my understanding thus far: - We were running mysqlclient 1.3.x which I believe led to incorrect values in the `DAG.run_type` field. - this led to calculating the wrong dates for `next_dagrun` and `next_dagrun_create_after` as the value of most_recent_dag_runs was incorrect. - This caused the scheduler to recreate old runs which then led to Duplicate Entry errors ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
