More specifically, if we want a specific flow to have one and only one flow run “Running” at a certain point in time, we need to make use of prefect flow concurrency labels in the following manner: 1. Create a flow concurrency label if it doesn’t exist. 2. Make sure the label is used when calling

flow.register()

3. Check the agent labels to see if this label already exists 4. If the label doesn’t exist, edit the agent deployment to add the label . This approach currently requires editing and re-deploying the agent each time a new flow is registered - which seems like a bit of an overkill

I guess it would be nice if there is a “global configuration” one can set in prefect cloud to make it the default for every flow in case what I mentioned is the only approach to achieve this
