Airflow - purge all the DAG entries from Web UI for all the deleted DAG files from dags_folder at once

Question

After deleting multiple DAG files from the dags folder, need to run airflow delete_dag dag_id for each DAG or delete the DAG entries one by one from the web UI.

Instead of doing this, is there a functionality or command to purge the deleted DAGs at one go?

Answer 1

You can always execute queries against your Airflow database directly; we have an Airflow process which cleans up our database periodically by removing entries from log, task_fail, etc.

As with anything regarding making changes to your database, make sure you have a backup.
