Simplifying Data Management with DAG Factory - Airflow Summit 2025

Presented by Katarzyna Kałek, Jakub Orłowski at Airflow Summit 2025. At OLX, we connect millions of people daily through our online marketplace while relying on robust data pipelines. In this talk, we explore how the DAG Factory concept elevates data governance, lineage, and discovery by centralizing operator logic and restricting direct DAG creation. This approach enforces code quality, optimizes resources, maintains infrastructure hygiene and enables smooth version upgrades. We then leverage consistent naming conventions in Airflow to build targeted namespaces, aligning teams with global policies while preserving autonomy. Integrating external tools like AWS Lake Formation and Open Metadata further unifies governance, making it straightforward to manage and secure data. This is critical when handling hundreds or even thousands of active DAGs. If the idea of storing 1,600 pipelines in one folder seems overwhelming, join us to learn how the DAG Factory concept simplifies pipeline management. We’ll also share insights from OLX, highlighting how thoughtful design fosters oversight, efficiency, and discoverability across diverse use cases.
