# Running on Schedule
With general availability of Prefect 2, we recommend new users start with Prefect 2.
Follow along in the Terminal
cd examples/tutorial python 05_schedules.py
Now that our Aircraft ETL flow is trustworthy enough, we want to be able to run it continuously on a schedule. Prefect provides
Schedule objects that can be attached to
from datetime import timedelta, datetime from prefect.schedules import IntervalSchedule # ... task definitions ... schedule = IntervalSchedule( start_date=datetime.utcnow() + timedelta(seconds=1), interval=timedelta(minutes=1), ) with Flow("Aircraft-ETL", schedule=schedule) as flow: airport = Parameter("airport", default="IAD") radius = Parameter("radius", default=200) reference_data = extract_reference_data() live_data = extract_live_data(airport, radius, reference_data) transformed_live_data = transform(live_data, reference_data) load_reference_data(reference_data) load_live_data(transformed_live_data)
flow.run() our flow will never stop, always starting a new run every minute.
More on Schedules
There are several ways to configure schedules to meet a wide variety of needs. For more on Schedules see our docs.
