>Airflow was developed at Airbnb to enable easier authorship and

>by its file system tree and one can find himself/herself traversing
>the file system when inspecting or changing the structure of the DAG.
>Airflow workflows, on the other hand, are simply and elegantly defined
>in Python code, often a single file. Airflow merges the powerful
