Se você simplesmente não sabe, use apenas `def`.

---

**Note**: Você pode misturar `def` e `async def` nas suas *funções de operação de rota* tanto quanto necessário e definir cada função usando a melhor opção para você. FastAPI irá fazer a coisa certa com elas.

De qualquer forma, em ambos os casos acima, FastAPI irá trabalhar assincronamente e ser extremamente rápido.

max_wait  (duration)  maximum wait time between operations, defaults to '15s'
cycle     (duration)  time duration between scanner cycles
```

Example: the following setting will decrease the scanner speed by a factor of 3, reducing the system resource use, but increasing the latency of updates being reflected.

```sh
~ mc admin config set alias/ scanner delay=30.0
```

## Características de Starlette

**FastAPI** está basado y es completamente compatible con <a href="https://www.starlette.io/" class="external-link" target="_blank"><strong>Starlette</strong></a>. Tanto así, que cualquier código de Starlette que tengas también funcionará.

`FastAPI` es realmente una sub-clase de `Starlette`. Así que, si ya conoces o usas Starlette, muchas de las características funcionarán de la misma manera.

Si simplemente no lo sabes, usa `def` normal.

**Nota**: puedes mezclar `def` y `async def` en tus *path operation functions* tanto como lo necesites y definir cada una utilizando la mejor opción para ti. FastAPI hará lo correcto con ellos.
