Question

Hi there If I skipped some schedules in the backend can I replan them Even if I recreate the schedule with an other time cron daily it will no recreate the skipped schedules

Dylan · Answer

Hi < Michael Hadorn> Let me see if I can help = Do you mean that you re skipping scheduled Flow Runs Or that you re setting a schedule to active or inactive If you skip a scheduled Flow Run you ll need to manually create a new run to replace it if you do want it to run

Hi < Dylan> I canceled a schedule flow run by mistake Ah ok there is no other way At this point it s not terrible was on development but if it happens on PRD it s not that cool to recreate manually schedules till the ordinary schedules takes over again Only to be clear I have a schedule that creates planned flow runs i canceled one from the future now I can not automatically let them recreate e g drop the schedule and recreate or put the state of the canceled flow run back to scheduled

Dylan · Answer

Let me make sure we re saying the same thing =

Dylan · Answer

You can absolutely recreate Schedules

Dylan · Answer

If you remove a schedule from a Flow you can create an identical one from the UI and it will behave as expected

Dylan · Answer

If you cancel a specific Flow Run set for the future Prefect won t automatically schedule a new Flow Run for that time

Dylan · Answer

You could try turning the schedule off and on again no seriously this might work because that deletes the future runs in the Prefect Cloud db and re creates them

Dylan · Answer

You can change the state of the cancelled flow run with a scheduled start time still in the future and change its state to scheduled

Dylan · Answer

At that point Prefect will run it on time as normal thumbsup

Michael Hadorn · Answer

thx for clarify ^^ btw I use prefect 0 14 6 and I use the local backend I tried all this but it s not working all the time the new schedules will be planned after my canceled one even if i recreate an schedule planned on a other time If i put the state of an canceled to scheduled it was run immediately I had daily flow runs planned 1 2 3 4 canceled 1 2 = gt 3 4 still there I deleted the schedule no scheduled flow runs recreated the schedule 3 4 showing up again 1 2 not then i think this is an issue Or did i mess something up sweat smile

Dylan · Answer

Nope I believe this is all intentional I just forgot a few specifics smile

Dylan · Answer

If you manually cancel a run in the future Prefect takes steps to make sure that run won t happen even if you turn the schedule on and off

Dylan · Answer

Changing the state in the UI to Scheduled shouldn t have an immediate impact unless the Scheduled Start Time is now or in the past

Dylan · Answer

In which case the run should be picked up immediately

Dylan · Answer

Also remember

Dylan · Answer

You can have more than one Flow Run at the same time for a Flow

Dylan · Answer

So if you manually cancel 1 2 you can just use the UI to create totally new Flow Runs with identical parameters amp start times and they ll run

Dylan · Answer

Even if you have a cancelled Flow Runs occurring at the same time

Dylan · Answer

In the future if you don t want some runs to happen during testing etc I d turn off the schedule instead of cancelling individual runs

Michael Hadorn · Answer

thx a lot for you help ok so i can not delete a schedule and recreate a new one like there was no schedule ever before If this is the case i think it is a little mysteriously delete schedules should never have an impact also not canceled flow runs on new schedules or I still didn t understand confused

Dylan · Answer

If you delete a schedule and then create an identical one it should schedule future Flow Runs like there was no schedule previously

Dylan · Answer

If you simply turn a schedule off and back on again it should remember the spots that you manually cancelled At which point you can create duplicate Flow Runs or set those Flow Runs to scheduled

Dylan · Answer

Can you open an issue with all of the details you can Including 1 screenshots 2 steps to reproduce 3 the behavior you expected 4 the behavior that occurred

Dylan · Answer

This sounds like suboptimal behavior but without seeing exactly what you are it s hard to know for sure

Michael Hadorn · Answer

yes i will add it there thx you a lot for your support It s really awesome how you respond everywhere

Michael Hadorn · Answer

< Dylan> I tried my best

Dylan · Answer
