Restarting Airflow scheduler does not remove the old Metadata. That metadata about historical DagRuns and Task instances is stored in Airflow Metadata DB (Postgres, MySQL etc) as shown in https://airflow.apache.org/docs/apache-airflow/stable/concepts/overview.html You should use a managed DB service like Cloud SQL or AWS RDS and not use ephemeral storage like Postgres in Kubernetes Pod etc. -- This is an automated message from the Apache Git Service.
