Prefect Community

Hi all, I'm evaluating Prefect and I'm wondering how it handles mutual exclusion or dynamic scheduling of flows based on the state of other flows. Basically, if flows A and B both need exclusive use of some resource, can I set up Prefect to know that B should pause until A completes?

It seems like task tag limits could be used for this, so maybe that's the answer

Yup! As of right now that’s the best way to go about this :thumbsup:

We’re also working on Flow Run limiting, so if you have finite resources in the flow execution environment you don’t overwhelm it. Stay tuned for updates on that front!
