Exercise

Specifying the DAG schedule

While cron is old, its succinct syntax is used in many programs, even in Airflow! It shows its head when we instantiate a DAG and tell the Airflow scheduler when a certain time-based task needs to be run. In an Airflow DAG, you can do this by passing a cron expression to the schedule_interval parameter.

In this example exercise, you will create a DAG that should be triggered every Monday, at 7 o’clock in the morning.
