Issue
I have an Airflow DAG that runs every hour. However, I need to schedule it only between the 0~30 minute of each hour.
Example: 11:00-12:00 12:00-13:35 14:00-
Setting "0-30/60 * * * *" does not apply the desired condition to execute only between 0 and 30 minutes past the hour. To achieve the desired schedule where the task runs only after the previous schedule has ended and between 0 and 30 minutes past the hour?
Solution
To schedule a cron job to run every hour between minutes 0 and 30, you can use the following cron expression:
0-30 * * * *
To prevent a new run from starting if the previous run has not finished, you can set catchup=False in your DAG definition
