Hi Prefect Experts - Is it possible if I have a flow run thats in a failed/cancelled state, to clear the state of a task thats already succeeded so that when the flow is restarted the previously successful task will re-execute? I know you can do that sort of thing with Airflow, but wasn't able to replicate with Prefect.

At this point though, doesn’t a new flow run give you what you are intending?

Not if Task1 takes 6 hours to run.

We can explicitly cache Task 1 so that it doesn’t re-run across flow runs. That would be the easier approach then moving those successful tasks back to Scheduled

Thanks! I will give this a shot.

Would changing the state of Task2 to Scheduled achieve the desired result? E.g. Task2, Task3, and Task4 are executed

Not quite, I think Task 2 will re-run but Task 3 won’t because it’s already in a SUCCESS state. You need all of them to be moved to a Scheduled state

Is it possible to change the state of a task? I thought you could only change the state of the overall flow run.

You can, you can even do it through the UI. Just navigate to a task run page and set the state

Thanks! Im not sure how I overlooked that.
