May 01, 2019 · Luckily, Airflow has the capability to securely store and access this information. Account credentials where the security does not really matter can be placed in the Python script as shown above where it says ‘MY_…’. All other account credentials whose information needs to be private and secure will have to be included in the Airflow UI.

You’ll probably want to subclass Airflow’s BaseOperator when building your own operators. When you do this you can add an on_failure_callback as a parameter to the parent BaseOperator class. You can pass a function that looks like this, done in the same style as my celery-slack Python package. You’ll have to ensure that the webhook is ...

Dec 13, 2019 · Professional BI Engineer that develops in Python 3.6. While I think Airflow is the future of creating and managing ETL there is some existing ETL that I support that uses Luigi…and I find myself pulling out my hair every time I need to figure out anything with it (but that could also be due to the code base that I inherited).
We added a callback function on_failure in the default_args under on_failure_callback. When the function is called with notify=True, an SMS is sent to a selected phone number from our Twilio number. The callback is instantiated with context from the failed DAG. We can use this argument to send a more explicit SMS that helps us know what went wrong.

Databricks also has a decent tutorial on setting up airflow. The difficulty here is that the airflow software for talking to databricks clusters (DatabricksSubmitRunOperator) was not introduced into airflow until version 1.9 and the A-R-G-O tutorial uses airflow 1.8. Airflow 1.9 uses Celery version >= 4.0 (I ended up using Celery version 4.1.1).
