Apache Airflow is an open-source tool for creating and managing complex workflows. More recently, Airflow has been gaining a lot of traction and popularity among data scientists for managing machine learning workflows. With increasing usage, we can see user expectations increase too. Like all users, we also expect tools to be reliable, scalable and work out of the box. The Apache Airflow community is working on improving all of these aspects. The recent joint effort of Databand and Polidea has brought many performance improvements to the core of Airflow.
