Question

Hi I using prefect 2 2 I have a use case that looks something like this A data file has been created I create a flow run using the client API with the file path as a parameter At the end of the flow if it has not errored then I want more tasks to run but I need it to wait for a particular interval day week I could do this with my own external scheduling system that I have not written but I would love to do that within prefect if possible So my question within a `flow` is there a way to schedule a subflow to start at a particular time in the future Or some other way to accomplish a long delayed subflow task

Taylor Curran · Answer

Yes Dylan there are many ways this could be accomplished

Taylor Curran · Answer

Have you checked out `prefect client` from our Python API <https docs prefect io api ref prefect client >

Taylor Curran · Answer

In which you can <https docs prefect io api ref prefect client prefect client OrionClient create flow run from deployment|create a flow run from deployment>

Taylor Curran · Answer

This is an example in which <https discourse prefect io t how to create a flow run from deployment orchestrator pattern 803|a flow can run inside of a flow>

Dylan McReynolds · Answer

< tc prefect> Yes thanks I m using the Orion client to kick of the initial flows However I don t see a way to schedule the flow run to not start until say 1 day from now

Dylan McReynolds · Answer

And I also don t see a way to schedule a flow to launch a subflow but not until 1 day from now I suppose I could simply put a 24 hour pause in the parent flow but it seems like I d start backing up hundreds of flows a day

Taylor Curran · Answer

I wonder if you <https docs prefect io api ref prefect client prefect client OrionClient create deployment|create a new deployment> with the desired schedule 24h+now

Dylan McReynolds · Answer

Hmmmm but then I d be creating hundreds of deployments a day for the same flow

Dylan McReynolds · Answer

or maybe I misunderstood

Taylor Curran · Answer

I m pretty sure we ve set up deployments to handle complex scheduling like you re describing I ve actually reached out to a colleague that might know more than me We ll get back to you later sorry I couldn t answer of the top of my head

Taylor Curran · Answer

And do let us know if you ve found something

Taylor Curran · Answer

Hi < Dylan McReynolds> another person named < Dylan> has come in clutch with a possible solution Could you use the state argument in the create flow run from deployment method to set state= scheduled time=now+24 something like ```client create flow run state=Scheduled scheduled time= ``` Will you let us know how this goes
