Bring your towel and join one of the fastest growing data communities. Welcome to our second-generation open source orchestration platform, a completely rethought approach to dataflow automation.

Prefect Community

What’s the best practice for running a flow of flows locally?

Using Prefect 2.0 :smile: this way, you don't have to register your subflows and you can call them from other flows almost as if they were tasks

in Prefect 1.0, you have to, unfortunately, register your child flows before calling them in a parent flow as those are technically not "subflows" but the orchestrator pattern triggering flows via an API call (thus, their metadata must exist in the API backend first)

Thanks so much Anna! Do you have an estimate as to when Prefect 2.0 will be out of beta?

It's easiest to just follow <https://discourse.prefect.io/tag/release-notes|release-notes> on Discourse, we ship new releases iteratively.
