Schedule a DAG in airflow to run every 5 minutes

问题

I have a DAG in airflow and for now it is running each hour (@hourly). Is it possible to have it running each 5 minutes ?

回答1:

Yes, here's an example of a DAG that I have running every 5 min:

dag = DAG(dag_id='eth_rates',
          default_args=args,
          schedule_interval='*/5 * * * *',
          dagrun_timeout=timedelta(seconds=5))

schedule_interval accepts a CRON expression: https://en.wikipedia.org/wiki/Cron#CRON_expression

回答2:

The documentation states:

Each DAG may or may not have a schedule, which informs how DAG Runs are created. schedule_interval is defined as a DAG arguments, and receives preferably a cron expression as a str, or a datetime.timedelta object.

When following the provided link for CRON expressions it appears you can specify it as 5 0 0 0 0 0 to run it every 5 minutes.

I'm not familiar on the matter, but this is what the documentation states.
