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.
