Data engineering teams can now execute custom Python and Bash code within MWAA Serverless using PythonOperator and BashOperator without managing separate infrastructure. Code packages are uploaded to Amazon S3 and snapshotted at workflow creation for consistent runs.

This enhancement enables common data processing tasks like transformation and quality checks to be integrated directly in Airflow-managed workflows, improving agility and reducing operational overhead. The feature is broadly available in supported AWS regions to facilitate serverless workflow automation.
