Schedule a DAG via Python

You've learned quite a bit about creating DAGs, but now you would like to schedule a specific DAG on a specific day of the week at a certain time. You'd like the code include this information in case a colleague needs to reinstall the DAG to a different server.

The Airflow DAG object and the appropriate datetime methods have been imported for you.

Instructions

  • Set the start date of the DAG to November 1, 2019.
  • Configure the retry_delay to 20 minutes. You will learn more about the timedelta object in Chapter 3. For now, you just need to know it expects an integer value.
  • Use the cron syntax to configure a schedule of every Wednesday at 12:30pm.
