Apache Airflow® 3 is here, bringing major improvements to data orchestration. In this keynote, core Airflow contributors will walk through key enhancements that boost flexibility, efficiency, and user experience. Vikram Koka will kick things off with an overview of Airflow 3, followed by deep dives into DAG versioning (Jed Cunningham), enhanced backfilling (Daniel Standish), and a modernized UI (Brent Bovenzi & Pierre Jeambrun). Next, Ash Berlin-Taylor, Kaxil Naik, and Amogh Desai will introduce the Task Execution Interface and Task SDK, enabling tasks in any environment and language. Jens Scheffler will showcase the Edge Executor, while Constance Martineau, Tzu-ping Chung and Vincent Beck will demo event-driven scheduling and data assets. Finally, Buğra Öztürk will unveil CLI enhancements for automation and debugging. This keynote sets the stage for Airflow 3—don’t miss the chance to learn from the experts shaping the future of workflow orchestration!

Airflow v2 architecture has strong coupling between the Airflow core & the User Code running in an Airflow task. This poses barriers in security, maintenance, and adoption. One such threat is that user code can access the source of truth of Airflow - the metadata DB and run any query against it! From a scalability angle, ‘n’ tasks create ‘n’ DB connections, limiting Airflow’s ability to scale effectively. To address this we proposed AIP-72 – a client-server model for task execution. The new architecture addresses several long-standing issues, including DB isolation from workers, dependency conflicts between Airflow core & workers, and ‘n’ number of DB connections.The new architecture has two parts: Execution API Server: Tasks no longer have direct DB access, they use this new slim, secure API Task SDK: A lightweight toolkit that lets you write tasks without drowning within Airflow’s codebase Beyond isolation and security, the redesign unlocks the ability for native multi-language task authoring support, and secure Remote Execution. Join us to explore how AIP-72 transforms Airflow task execution, paving the way for a more secure, flexible, and futuristic task orchestration!

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

Ready to contribute to Apache Airflow? In this hands-on workshop, you’ll be expected to come prepared with your development environment already configured (Breeze installed is strongly recommended, but Codespaces works if you can’t install Docker). We’ll dive straight into finding issues that match your skills and walk you through the entire contribution process—from creating your first pull request to receiving community feedback. Whether you’re writing code, enhancing documentation, or offering feedback, there’s a place for you. Let’s get started and see your name among Airflow contributors!
