Not exactly — there is no

ContinuousSchedule

type in Prefect 3.x. Prefect 3.x deployments support these schedule types: -

Interval

-

Cron

-

RRule

So if by “continuous schedule” you mean a literal

ContinuousSchedule

, the answer is no. If you mean “run continuously / as often as possible,” the closest option is usually an interval schedule, for example every few seconds:

python
from datetime import timedelta
from prefect import flow
from prefect.schedules import Interval

@flow
def my_flow():
    print("running")

if __name__ == "__main__":
    my_flow.serve(
        name="my-deployment",
        schedule=Interval(timedelta(seconds=1))
    )

A few caveats: - Prefect schedules create scheduled flow runs at defined times — they are not a “while true” continuous process. - If the flow runtime is longer than the interval, runs can overlap unless you add concurrency controls. - Extremely frequent schedules can put load on your work pool / workers and on the API. If you want, I can help you choose between: - a very short

Interval

- an

RRule

- a long-running polling flow pattern instead of scheduling Docs: Schedules in Prefect 3
