In https://github.com/PrefectHQ/prefect/issues/470 throttling was removed and it says that “We will replace it with a robust, global solution.” Has there been any replacement or progress on implementing any sort of flow throttling? Specifically I’m looking to limit the number of concurrently running flows based on certain criteria.

Hi! Right now there are flow level concurrency limits in the Prefect Cloud offering and considerations to include them in Prefect server (https://github.com/PrefectHQ/server/issues/81)

Following up on what Michael said, there is also a more granular concurrency limiting feature in Prefect Cloud that allows you to limit the global concurrency of certain tasks based on their tags, but access to this feature requires an appropriate Cloud license

Thanks!
