The Airflow project is rapidly evolving, with more frequent releases bringing advancements in DAG authoring, observability, and project stability. We’re excited about the release of Airflow 2.5 because it has notable updates and quality-of-life improvements touching big features like dynamic task mapping, sensors, task groups, datasets, and the UI.

Key Takeaways

In this webinar, we’ll cover all the great 2.5 updates that make Airflow even easier to use and implement at scale. We’ll spend extra time on exciting new features like:

  • Dynamic mapping over task groups, which makes the dynamic task mapping feature even more flexible.
  • Updates to the datasets UI, including filtering and search capabilities.
  • A new @sensor decorator that lets you turn any Python function into a sensor.
  • Updates to XCom, particularly for dynamically mapped tasks.
