one small question! is there a way to run deployment parallely?

Yup, a for loop, run_deployment utility and setting timeout to 0 will do the trick. Check an example here https://discourse.prefect.io/t/how-to-run-deployments-with-ecstask-infrastructure-block-at-scale-running-hundreds-of-serverless-ecs-containerized-flow-runs-concurrently/1929/1

But this marks the main flow as successful right away I want to wait for these deployment runs to be successful to mark the flow as successful

In that case, you can call run_deployment from a task and run those tasks concurrently

Yeah that I’ve tried . It is getting stuck on the assertion error for now . As soon as the assertion error gets fixed we will be good to go forward with prefect for our production environment

Great to hear! 💯 And thanks so much for the issue
