of uniqueness over space and time and are computationally difficult to guess. They are globally unique identifiers which can be locally generated without contacting a global registration authority. UUIDs are intended as unique identifiers for both mass tagging objects with an extremely short lifetime and to reliably identifying very persistent objects across a network.

When you PUT an object in a versioning-enabled bucket, the noncurrent version is not overwritten. The following figure shows...

Beachten Sie, dass der Defaultwert weiterhin `None` ist, so dass der Parameter weiterhin optional ist.

Aber jetzt, mit `Query(max_length=50)` innerhalb von `Annotated`, sagen wir FastAPI, dass wir eine **zusätzliche Validierung** für diesen Wert wünschen, wir wollen, dass er maximal 50 Zeichen hat. 😎

        EventType type = success ? EventType.AUTHENTICATION_SUCCESS : EventType.AUTHENTICATION_FAILURE;
        Severity severity = success ? Severity.INFO : Severity.WARNING;

```

... das liegt daran, dass der Client-Generator für jede *Pfadoperation* die OpenAPI-interne **Operation-ID** verwendet.

OpenAPI erfordert, dass jede Operation-ID innerhalb aller *Pfadoperationen* einzigartig ist. Daher verwendet FastAPI den **Funktionsnamen**, den **Pfad** und die **HTTP-Methode/-Operation**, um diese Operation-ID zu generieren. Denn so kann sichergestellt werden, dass die Operation-IDs einzigartig sind.
