Hi everybody! Is there a way to run multiple schedules? I would like a schedule that runs every hour, and then one that runs twice a day, both that call the same function, but handle the result differently 🙂

Hi @source_creator! Would a

UnionSchedule

work for your needs? https://docs.prefect.io/api/unreleased/schedules.html#unionschedule You’d probably have to write some custom logic inside your task to handle the result differently for each schedule

Hi @Chris White,thank you for your reply! With the custom logic approach - how would I detect which schedule called the task, from inside the task?

i’d recommend pulling the scheduled start time from context and using that to infer which schedule was called: https://docs.prefect.io/api/unreleased/utilities/context.html

Hmm I think I am missing something. Can I check the context in the Flow? I have setup the

UnionSchedule

, but I am stuck

from within a task you can check the context; for example,

@task
def get_todays_date():
    today = prefect.context.get("today")
    print(today)
    return today

I see - I managed to get the scheduled start time from the context, and I can differentiate between the 2 schedules. It's not as nice as I would like, but it's a solution. Thanks Chris!

hmmmmm I’ll have to take a look at that --> I’m not sure why that would be the case; would you mind opening an issue for it on our github repo?

Hmm seems like it was my misunderstanding, thinking

start_date

passed to

IntervalSchedule

was the same as

scheduled_start_time

from the context in the Task
