Can you implement a "manual" task in a middle of a workflow with prefect? The expected behavior would be something like: the workflow stops to the manual steps. Once the work is done, somebody, from the web interface, mark the task as done, and the workflow continue its job.

Yup! The building blocks for this have been in place for a long time but I think people are just starting to use it (based on questions) so we’ll be taking a look at the UX (both in code and in the UI) in the near future to improve it 🙂 It’s actually simple - any task can put itself into a

PAUSE

state, and all automatic progression will stop. To continue, put it into a

RESUME

state manually (via GraphQL, code, or the UI). The one caveat is that your task logic needs to check for a special value

prefect.context.get('resume') is True

so that it can tell if it was put into the

RESUME

state and run itself appropriately.

Pro-tip: if you use a

manual_only

trigger on a Task, Prefect takes care of context for you

Ah thank you @Chris White

OK. Thanks. Do you have some code sample to share? I'm starting with Prefect, give it a try and still don't have a good understanding of it ;)

Hi @Nicolas Michel - check out this issue for a code snippet and some work being done to improve this API: https://github.com/PrefectHQ/prefect/issues/2615
