The amount of RAM required for Apache Airflow depends heavily on your overall data scale, deployment environment, and chosen task executor. For a basic local development and testing environment utilizing Docker Compose, at least 4 GB to 8 GB of dedicated RAM is recommended to ensure the webserver, scheduler, metadata database, and worker nodes run smoothly. In large enterprise production clusters processing heavy data loads, Airflow deployments frequently scale to 16 GB, 32 GB, or more across distributed worker nodes.
