Hello guys, I would like to know if in Prefect 2.0 it is possible to request the execution of a specific task and all its dependent upstream tasks. Thanks.

I know this is an intended use case behind 2.0, but I need to check if it can already be done

thank you @Kevin Kho . i’m working on a use case that requires to create a dynamic flow and the ability to run a specific task + all upstream tasks. would be great to use Prefect 2.0 on this one.

ok i chatted with some team members and it doesn’t work like this. it’s more like you can package things as a subflow and retry the subflow because the subflow is like a task, but you don’t retry the upstream tasks per se
if you have 1 flow with A->B->C and A and B succeed but C fails, you can’t restart A and B
Ok talked more and you can’t resubmit the subflow, it’s more like you’d kick off another subflow. So basically it’s similar to 1.0, my first answer was wrong
