how do i wait for completion of a subflow before running another subflow?

I believe sub-flow runs after sequential by default

Yeah: <https://docs.prefect.io/2.13.8/concepts/flows/#composing-flows>

```Subflows will block execution of the parent flow until completion. However, asynchronous subflows can be run in parallel by using AnyIO task groups or asyncio.gather.```

sorry i mean subflows created using run_deployment within a flow

I think you could do this with a concurrency limit: <https://docs.prefect.io/latest/guides/global-concurrency-limits/|https://docs.prefect.io/latest/guides/global-concurrency-limits/>
