Sie können die Eigenschaft `.openapi_schema` als „Cache“ verwenden, um Ihr generiertes Schema zu speichern.

Auf diese Weise muss Ihre Anwendung das Schema nicht jedes Mal generieren, wenn ein Benutzer Ihre API-Dokumentation öffnet.

Es wird nur einmal generiert und dann wird dasselbe zwischengespeicherte Schema für die nächsten Requests verwendet.

### Ler Heroes

Podemos **ler** `Hero`s do banco de dados usando um `select()`. Podemos incluir um `limit` e `offset` para paginar os resultados.
