The Apache Airflow Newsletter Airflow Community News & Events Introduction This year’s Airflow Summit is fast approaching. The organizers received a great number of proposals – over 100. The CFP closed on March 14, but you can still register <https://www.crowdcast.io/e/airflowsummit2022/register> to attend the biggest Airflow event of the year. March was another eventful month for the project. Airflow hit 2k contributors! 🎉 A new Helm chart release (1.5.0 <https://airflow.apache.org/docs/helm-chart/1.5.0/installing-helm-chart-from-sources.html>) appeared, along with new versions of the Airflow Providers packages <https://airflow.apache.org/docs/apache-airflow-providers/installing-from-sources>. They can be installed via PyPI <https://airflow.apache.org/docs/apache-airflow-providers/installing-from-pypi>. Also, long-awaited support for Python 3.10 and robust support for development on MacOS M1 architecture are finally a reality. The relevant PRs (#22127 <https://github.com/apache/airflow/pull/22127> and #22050 <https://github.com/apache/airflow/pull/22050>) were merged on March 9 and March 21, respectively. The newsletter is moving to a new platform next month. Please subscribe to ensure you always receive the latest issue: http://eepurl.com/hXUA3r <http://eepurl.com/hXUA3r>. Summit Stats & Facts Free and online (with in-person events in many places) this May 23-27, the summit will feature not only tech talks but also deep dives, panels, lightning talks, workshops, and case studies from practitioners and data leaders across the global Airflow community. Sessions will be scheduled for different time zones to accommodate as many members as possible. This year’s session tracks are: Trends, Data Governance, Productionizing Machine Learning, Airflow Internals, Airflow in Enterprise, Community, and Open. A new kind of event will make this year’s summit unusual: local in-person meetups. Members in a number of cities will be able to attend in-person events, join watch sessions, and network. Twelve such events are planned for Amsterdam, Bengaluru, Lagos, London, Melbourne, New York City, Paris, Sao Paulo, Seattle, Sydney (tentative), Tel Aviv, Tokyo, and Warsaw!

Here's a bird's-eye view of the session breakdown by format, length, and track: <https://www.crowdcast.io/e/airflowsummit2022/register> 🚀 Releases & Documentation Improvements 🚀 On March 11, we released Apache Airflow Helm chart 1.5.0. 📦 ArtifactHub: https://artifacthub.io/packages/helm/apache-airflow/airflow <https://artifacthub.io/packages/helm/apache-airflow/airflow> 📚 Docs: https://airflow.apache.org/docs/helm-chart/1.5.0/ <https://airflow.apache.org/docs/helm-chart/1.4.0/> 🛠️ Changelog: https://airflow.apache.org/docs/helm-chart/1.5.0/changelog.html <https://airflow.apache.org/docs/helm-chart/1.4.0/changelog.html> 🪶 Sources: https://airflow.apache.org/docs/helm-chart/1.5.0/installing-helm-chart-from-sources.html <https://airflow.apache.org/docs/helm-chart/1.4.0/installing-helm-chart-from-sources.html> On March 10, we released new versions of the Airflow Providers packages. 📚 Docs: https://airflow.apache.org/docs/apache-airflow-providers/installing-from-pypi <https://airflow.apache.org/docs/apache-airflow-providers/installing-from-pypi> 🪶 Sources: <https://airflow.apache.org/docs/apache-airflow-providers/installing-from-sources>https://airflow.apache.org/docs/apache-airflow-providers/installing-from-sources <https://airflow.apache.org/docs/apache-airflow-providers/installing-from-sources> 🗓️ Upcoming Events 🗓️ We can always use speakers for meetups.

On February 28, the PyLadies BCN group in Barcelona hosted a meetup, “Introduction to Apache Airflow.” <https://www.meetup.com/PyLadies-BCN/events/283989295/> #19857 Enable JSON serialization for secrets backend <https://github.com/apache/airflow/pull/19857> Daniel <https://github.com/dstandish> says, “Until now, to store an Airflow connection in an environment variable or secrets backend you had to express the connection in an Airflow-specific URI format. (If you’ve done this you know how painful it can be.) With this PR, we can now define connections using JSON, which is much more user-friendly. “For me the idea first came to mind when in the course of reviewing a secrets backend PR I learned that our local filesystem secrets backend supported JSON. I didn’t work on it at the time, but later I had a use case at my company: using one creds store for both Airflow and a Jupyter notebook environment. So I implemented a JSON AWS SSM secrets backend, and it was so much nicer to work with. And then I knew as soon as I had a little extra time I wanted to contribute it, and not for just AWS SSM but all secrets backends.” We’re eager to recognize the incredible people in the community for their work on Apache Airflow. This month we’re introducing Jed Cunningham (jedcunningham <https://github.com/jedcunningham>), Airflow PMC member and Senior Software Engineer on Astronomer’s OSS Airflow Engineering Team. Where are you based? Denver, CO, USA Why did you start contributing to the project? If I went through the effort to fix a bug or add a small feature, I wanted the whole community to benefit from my effort. I also didn’t want to maintain my own fork of Airflow. What do you use it for? Currently I really only use Airflow when I’m working on Airflow :), but I’ve run Airflow for data teams who relied on it to orchestrate and have visibility into data-heavy jobs primarily using KubernetesPodOperator. When was your first PR and what was it? I opened my first PR in August 2020 to show tracebacks of DAG import errors in the UI. What was your latest? My latest PR added support for extraVolumeMounts in Flower in the Apache Airflow Helm Chart. What do you like about working on OSS projects? I really enjoy seeing the output of a diverse group of overwhelmingly friendly people and being a part of the community. I wholeheartedly welcome others to get involved as well: grab a good first issue, and if you get stuck we are friendly in the #airflow-how-to-pr slack channel! 📢 Communications Digest 📢 One of the most popular Astronomer articles about Airflow, “7 Common Errors to Check when Debugging DAGS <https://www.astronomer.io/blog/7-common-errors-to-check-when-debugging-airflow-dag/>,” was updated with new information on March 29.
