Usar `check_same_thread=False` permite que o FastAPI use o mesmo banco de dados SQLite em diferentes threads. Isso é necessário, pois **uma única requisição** pode usar **mais de uma thread** (por exemplo, em dependências).

Davor war der Umgang mit asynchronem Code jedoch deutlich komplexer und schwieriger.

In früheren Versionen von Python hätten Sie Threads oder [Gevent](https://www.gevent.org/) verwenden können. Der Code ist jedoch viel komplexer zu verstehen, zu debuggen und nachzuvollziehen.

Die Verwendung von `check_same_thread=False` erlaubt FastAPI, dieselbe SQLite-Datenbank in verschiedenen Threads zu verwenden. Dies ist notwendig, da **ein einzelner <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr>** **mehr als einen Thread** verwenden könnte (zum Beispiel in Abhängigkeiten).

L'utilisation de `check_same_thread=False` permet à FastAPI d'utiliser la même base SQLite dans différents threads. C'est nécessaire car **une seule requête** peut utiliser **plus d'un thread** (par exemple dans des dépendances).

        `MirroredStrategy.run` or `ReplicaContext.merge_call`. This is because a
        thread local variable is used to determine whether `AutoCastVariable`s
        are casted, and those two functions run with a different thread. Note
        this only applies if one of these two functions is called within
        `Layer.call`; if one of those two functions calls `Layer.call`,
