I am planning to run large Flow with the caching that seems to be working fine But lately I found out that if the same flow is started at almost similar time then the caching might not work as they both are running at the same time. Want to understand if there is a way to control this by not triggering the second flow when the first run is already in running state (with the same Parameter) using Prefect API or GraphQL query API

Hello Vipul! Before I suggest any options, could you please provide more information about your flows. Is there a specific reason for having the same flow running at the same time? Could you take advantage of using different schedule?

Hey, there are being triggered using Flask API and I don’t have much control over that

I see. You can pass an 

idempotency_key

 to

create_flow_run

that includes, for example, your parameter values as a string, or a timestamp to prevent multiple duplicate runs from being scheduled.
