Hey anybody got any way to wait on multiple flows at the same time that are created by `create flow run` Want to do something like

Joshua Greenhalgh · Answer

```with Flow backfill boot as backfill boot flow runs = for param in params flow run = create flow run flow name= flow name project name= production parameters=param flow runs append flow run wait for flow runs ```

Joshua Greenhalgh · Answer

Could probably create something on top of the `wait for flow run` task but was thinking maybe something existed already

Joshua Greenhalgh · Answer

This kinda works ``` for flow run in flow runs res = wait for flow run flow run ``` But each call to wait for flow run blocks would be nice to be able to stream the logs interleaved for all the flow runs I am waiting for

Hi Joshua by default prefect 1 0 runs sequentially You could try adding an executor if you want parallelism

James Sopkin · Answer

so for a code example ```with Flow backfill boot executor=LocalDaskExecutor as backfill boot ```

Joshua Greenhalgh · Answer

Thanks I don t think it really needs task parallelism to accomplish could have a single task that takes the ids you care about and within the task loop through and wait for each

Joshua Greenhalgh · Answer

I can probably write it myself though

James Sopkin · Answer

ahh in that case a for loop like the one you had should be fine then
