Multiple query fields are processed sequentially?

[sanchit-gupta-cn]

Hi everyone,

According to the GraphQL spec, multiple query fields are processed in parallel by a GraphQL server (Ref), but when working with ariadne, I observed that the fields in a single query operation were being executed sequentially (I am using Django along with ariadne.wsgi.GraphQL to serve my GraphQL server).

Is this the intended behavior, or am I missing something? Would be great if someone could help answer my doubt.

PS: Sorry if this seems like a trivial doubt. I am relatively new to GraphQL and ariadne.

GraphQL spec is written with one eye towards the graphql.js which is reference implementation that supports asynchronous query execution.

Python counterpart provides two query execution strategies: async and sync. This is because async is opt-in in Python projects. wsgi.GraphQ (as well as ariadne.contrib.django.views.GraphQLView) are using synchronous strategy because neither WSGI or Django are fully async stacks.

Parallel execution holds true for ariadne.asgi.GraphQL.

Hi @rafalp, thanks a lot for the explanation. We'll re-evaluate our stack and see if it is worth it to shift to an async one.
