Starlette(그리고 **FastAPI**)는 [AnyIO](https://anyio.readthedocs.io/en/stable/)를 기반으로 하고 있으며, 파이썬 표준 라이브러리 [asyncio](https://docs.python.org/3/library/asyncio-task.html)와 [Trio](https://trio.readthedocs.io/en/stable/) 모두와 호환됩니다.

특히, 코드에서 더 고급 패턴이 필요한 고급 동시성 사용 사례에서는 직접 [AnyIO](https://anyio.readthedocs.io/en/stable/)를 사용할 수 있습니다.

If you have an API that does a comparable amount of computations every time and you have a lot of clients, then the **CPU utilization** will probably *also be stable* (instead of constantly going up and down quickly).

Si vous avez une API qui effectue une quantité comparable de calculs à chaque fois et que vous avez beaucoup de clients, alors l'**utilisation du CPU** sera probablement *également stable* (au lieu de monter et descendre rapidement en permanence).

/// note | Technical Details

This only happens when you install using `uv sync --extra all` instead of running `pip install fastapi` directly.

That is because `uv sync --extra all` will install the local version of FastAPI in "editable" mode by default.

### Format the code

There is a script that you can run that will format and clean all your code:

<div class="termy">

```console
$ bash scripts/format.sh
```

- Removed the `CronJobTimeZone` feature gate (the feature is stable and always enabled)
  - Removed the `JobMutableNodeSchedulingDirectives` feature gate (the feature is stable and always enabled)
