Inside the Custom Framework for Managing Airflow Code at Wix with Gil Reich

Efficient orchestration and maintainability are crucial for data engineering at scale. Gil Reich, Data Developer for Data Science at Wix, shares how his team reduced code duplication, standardized pipelines, and improved Airflow task orchestration using a Python-based framework built within the data science team.

In this episode, Gil explains how this internal framework simplifies DAG creation, improves documentation accuracy, and enables consistent task generation for machine learning pipelines. He also shares lessons from complex DAG optimization and maintaining testable code.

Key Takeaways:

(03:23) Code duplication creates long-term problems.

(08:16) Frameworks bring order to complex pipelines.

(09:41) Shared functions cut down repetitive code.

(17:18) Auto-generated docs stay accurate by design.

(22:40) On-demand DAGs support real-time workflows.

(25:08) Task-level sensors improve run efficiency.

(27:40) Combine local runs with automated tests.

(30:09) Clean code helps teams scale faster.
