During January 2026, Musifer enhanced the potiuk/airflow repository by developing a targeted feature for the db_clean command, introducing DAG-based include and exclude options to enable precise database cleanup. This work involved backend development using Python, with a focus on command line interface design and database management. Musifer improved the reliability of the cleanup workflow by refining table handling logic for dag_id and dag_version, ensuring critical DAGs are preserved. The update also addressed deprecated SQLAlchemy usage to maintain compatibility, and included new tests and documentation updates. The depth of the changes reflects careful attention to workflow safety and maintainability.
