Another question 🙂 is it possible to have the following constraint: Schedule "flow a" to run every 10 minutes & prevent scheduling "flow a" if there is an existing invocation still running.

For Cloud, we have Flow Run Concurrency. For server, I have this code snippet from another Server user.

perfect, thank you!

Thank you! 🙂

For Prefect Cloud, with the concurrency based off the flow run config labels, does this mean that an agent has to be configured with specific labels to limit flows? For instance, say I have

source1-database-extract

and

source2-database-extract

flows that each flow should only have a single instance per source to prevent issues. Does this mean I have to add tags for every flow to the agent to ensure they can run only once per source?

Yes but flow labels just need to be a subset of agent labels of if you have a label for

source1

and another for

source2

, the agent can pick both up if it has both the labels. And then yes you would apply the concurrency limit on the

source1

label and on the

source2

label

Ok, thanks for the clarification!
