Hi, I have a question about this error :

ValueError: Interval can not be less than one minute when deploying to Prefect Cloud.

Why was that limit set ? Why can't I decide to schedule a job every second ?

This limit was set to prevent users from getting into bad situations with backpressure; most deployments of Prefect run in k8s, and the latency to create a k8s job can be non-trivial

Could this be a setting in a future version of Prefect ?

It depends on your use case; we will most likely not change the scheduler constraint but we have discussed “event driven” flows that correspond to possibly fast event streams that we do plan to support at some point

My use case is that I have a lot of agents and want to run a lot of flows every 15 seconds 😛

you can manually create ad hoc flow runs through the API, and there is no constraint as to how fast those can be created
