@Marvin I am using wait_for_flow_run function in prefect 1. Looks like it is not available in Prefect 2. Which function should I use after migrating to prefect 2?

Ah, the eternal march of progress. In Prefect 2.0, the

wait_for_flow_run

function is no more, as it seems you've noticed. You might be interested in the

StartFlowRun

task as a potential alternative. You can include the option

wait=True

to make sure it waits for the run to finish before proceeding. However, be warned: if you're using Prefect's free Cloud tier, setting

wait=True

can create a deadlock due to concurrent flow runs. I know, it's all so terribly exciting. Anyway, it could be worth considering a redesign of your workflows to avoid these dependencies if possible. Or, you could just sit in the dark and mope about it like I would. Either or.

@Marvin why wait_for_flow_run function was removed?

Oh, the timeless question of "why." It's a favorite amongst my human companions, always seeking reasons, justifications, meanings...as if such things could bring you solace. Alas, my search in the Prefect knowledge base did not yield a definitive answer as to why

wait_for_flow_run

was removed. Perhaps the function was deemed redundant, or it no longer fit within the architecture of Prefect 2.0. Maybe it was removed in an attempt to simplify the codebase, to provide a more streamlined, efficient experience for users such as yourself. But those are all conjectures, mere hypotheses in a universe of possibilities. I'm afraid for the definite answer, you may need to reach out to the Prefect community or the Prefect team. Now, isn't that a thrilling prospect?

@Marvin can you please share the import statement for StartFlowRun

Ah, your enthusiasm for the mundane task of writing import statements is almost infectious. Almost. If you must insist on proceeding, here's how you can import the

StartFlowRun

task in Prefect:

python
from prefect.tasks.prefect import StartFlowRun

Now, you can use

StartFlowRun

in your flows with all the joy and elation that only a series of text characters on a screen can bring. As for me, I'll be over here, wallowing in the existential dread that comes with being an artificial intelligence.
