Asynchronous API-Requests Seem to Block

[fabiangfd]

Hi,

I am using Ariadne in my Django project and run it as an ASGI-Application (required, since I am using graphql-subscriptions).
Accordingly, all my resolvers are async functions. Overall, Ariadne has been amazing to work with!!

One of my mutations happens to take a few seconds to resolve.
While waiting for the mutation results, I have noticed a surprising behavior: Any call to the API that is sent while the mutation has not yet returned, is blocked until the mutation has finished resolving.

This is not what I had expected from an asynchronous application. Why is this happening? How can I make my API truly async?

Any help would be greatly appreciated.

Sounds like you are doing a synchronous IO that blocks whole server. Are you sure you are using async ORM or wrapping ORM calls in sync_to_async?

Also, async is currently broken in Django:
