Hi everyone. In Prefect 1, is there a mechanism so that one task starts after another one starts and both tasks run in parallel?

But, when we define upstream tasks, downstream tasks should wait until they finish right? What I need is always starting a task after a specific task starts but not finished yet.

Unsure if that is available. U can always use the prefect api to query for status of previous task within the downstream task and then run the actual code after ur requirements are met. That's all I have . 🤷 Best of luck.

You can create a separate flow for your downstream task, and call start_run without waiting, this way you don’t have to wait on the upstream task to complete.. see https://docs-legacy.prefect.io/api/0.10.7/tasks/cloud.html#flowruntask

@Marwan Sarieddine thanks. It was what I was considering.
