2. "What we learned after running Airflow on Kubernetes for 2 years" by Alexandre Magno Lima Martins.
To put it in perspective, we have over 300 DAGs in production, running more than 5.000 tasks per day, on average. So I would say that we have a medium-size Airflow deployment, capable of delivering value for our users. For more than 8 months now we have been running without a single incident or failure in Airflow. With this post, I want to share important aspects of our deployment that helped us to achieve a scalable, and reliable environment.
