Airflow 3 comes with two new features: Edge execution and the task SDK. Powered by a HTTP API, these make it possible to write and execute Airflow tasks in any language from anywhere. In this session I will explain some of the APIs needed and show how to interact with them based on an embedded toy worker written in Rust and running on an ESP32-C3. Furthermore I will provide practical tips on writing your own edge worker and how to develop against a running instance of Airflow.

Profiling Airflow tasks can be difficult, specially in remote environments. In this talk I will demonstrate how we can leverage the capabilities of Airflow’s plugin mechanism to selectively run Airflow tasks within the context of a profiler and with the help of operator links and custom views make the results available to the user. The content of this talk can provide inspiration on how Airflow may in the future allow the gathering of custom task metrics and make those metrics easily accessible.
