Subject Re: Multiple similar DAGs
Date Wed, 01 Nov 2017 18:45:52 GMT
Hi Michael,

You could leverage the Variable feature in Airflow: start by setting a
different environment variable in each env, and then in your DAG file,
instead of hard-coding the schedule, call a method that looks up which
environment it is (using Variable.get) and returns the desired one.

Hope this helps!
