Have you ever wondered why Apache Airflow builds are asymptotically() green? That thrive for “perennial green build” is not magic, it’s the result of continuous, often unseen engineering effort within our CI/CD pipelines & dev environments. This dedication ensures that maintainers can work efficiently & contributors can onboard smoothly. To tackle the ever growing contributor base, we have a CI/CD team run by volunteers putting in significant work in the foundational tooling. In this talk, we reveal some innovative solutions we have implemented like: Handling GitHub Actions pull_request_target challenges Restructuring the repo for better clarity Slack bot for CI failure alerts A cherry picker workflow for releases Pre-commit hooks Faster website and image builds Tackling the new GitHub API rate limits Solving chicken-and-egg build issues during releases Join us to understand the “why” & “how” behind these infra components. You’ll gain insights into the continuous effort required to support a thriving open-source project like Airflow and, hopefully, be inspired to contribute to these areas. () asymptotically = we fix failures as quickly as we can when they happen

Apache Airflow relies on a silent symphony behind the scenes: its CI/CD (Continuous Integration/Continuous Delivery) and development tooling. This presentation explores the critical role these tools play in keeping Airflow efficient and innovative. We’ll delve into how robust CI/CD ensures bug fixes and improvements are seamlessly integrated, while well-maintained development tools empower developers to contribute effectively. Airflow’s power comes from a well-oiled machine – its CI/CD and development tools. This presentation dives into the world of these often-overlooked heroes. We’ll explore how seamless CI/CD pipelines catch and fix issues early, while robust development tools empower efficient coding and collaboration. Discover how you can use and contribute to a thriving Airflow ecosystem by ensuring these crucial tools stay in top shape.

Apache Airflow has over 650 Python dependencies. In case you did not know already, dependencies in Python are difficult subject. And Airflow has its own, custom ways of managing the dependencies. Airflow has a rather complex system to manage dependencies in their CI system, but this talk is not about it. This talk is directed to the users of Airflow who want to keep their dependencies updated, describing ways they can do it. This presentation will explain how to effectively manage and handle custom dependencies in Airflow. Jarek will guide you through practical solutions and best practices to make your Airflow experience with dependencies - yes you guessed it - a breeze.
