declare a *path operation function* with normal `def` instead of `async def`, it is run in an external threadpool that is then awaited, instead of being called directly (as it would block the server).

If you are coming from another async framework that does not work in the way described above and you are used to defining trivial compute-only *path operation functions* with plain `def` for a tiny performance gain (about 100 nanoseconds), please note that in **FastAPI** the effect would be quite...

          # This should only really import operator API, but that is hard to express without a larger refactoring
          - "!**/pkg/kube/**"
          - "!**/pkg/url/**"
          - "!**/pkg/test/framework/**"
          - "!**/tests/fuzz/**"
        deny:
          - pkg: istio.io/istio/operator
            desc: "operator should not be imported"
          - pkg: istio.io/istio/istioctl

For deployments with [bucket](https://min.io/docs/minio/linux/administration/bucket-replication.html) or [batch](https://min.io/docs/minio/linux/administration/batch-framework.html#replicate) configurations, these metrics populate instead under the [Bucket Metrics](#bucket-metrics) endpoint.

And it shows their true commitment to FastAPI and its **community** (you), as they not only want to provide you a **good service** but also want to make sure you have a **good and healthy framework**, FastAPI. 🙇

For example, you might want to try <a href="https://speakeasyapi.dev/?utm_source=fastapi+repo&utm_medium=github+sponsorship" class="external-link" target="_blank">Speakeasy</a>.

Actually, all (or most) of the web frameworks work in this same way.

You never call those functions directly. They are called by your framework (in this case, **FastAPI**).
