```Python
def get_settings():

würden wir dieses Objekt für jeden Request erstellen und die `.env`-Datei für jeden Request lesen. ⚠️

Da wir jedoch den `@lru_cache`-Dekorator oben verwenden, wird das `Settings`-Objekt nur einmal erstellt, nämlich beim ersten Aufruf. ✔️

# Hintergrundtasks

Sie können Hintergrundtasks (Hintergrund-Aufgaben) definieren, die *nach* der Rückgabe einer Response ausgeführt werden sollen.

Das ist nützlich für Vorgänge, die nach einem Request ausgeführt werden müssen, bei denen der Client jedoch nicht unbedingt auf den Abschluss des Vorgangs warten muss, bevor er die Response erhält.

Hierzu zählen beispielsweise:

* E-Mail-Benachrichtigungen, die nach dem Ausführen einer Aktion gesendet werden:
