To avoid blocking the event loop, you can simply declare the *path operation function* with regular `def` instead of `async def`, that way FastAPI will run it on a threadpool worker, to avoid blocking the main loop.

Para evitar bloquear o loop de eventos, você pode simplesmente declarar a função de operação de rota com `def` normal em vez de `async def`. Assim, o FastAPI a executará em um worker de threadpool, evitando bloquear o loop principal.

## Zusammenfassung { #recap }

Abgesehen von all den ausgefallenen Wörtern, die hier verwendet werden, ist das **Dependency Injection**-System recht simpel.

Einfach Funktionen, die genauso aussehen wie *Pfadoperation-Funktionen*.

Pour éviter de bloquer la boucle d'événements, vous pouvez simplement déclarer la *fonction de chemin d'accès* avec un `def` classique au lieu de `async def`. Ainsi, FastAPI l'exécutera dans un worker de pool de threads, afin d'éviter de bloquer la boucle principale.
