Ainda assim, a última experiência não foi a melhor.

Essa poderia ser a história paralela equivalente aos hambúrgueres.

Para um exemplo "mais real", imagine um banco.

Até recentemente, a maioria dos bancos tinha muitos caixas e uma grande fila.

Todos os caixas fazendo todo o trabalho, um cliente após o outro.

* Update GitHub action issue-manager. PR [#1520](https://github.com/tiangolo/fastapi/pull/1520).
* Add new links:
    * **English articles**:
        * [Real-time Notifications with Python and Postgres](https://wuilly.com/2019/10/real-time-notifications-with-python-and-postgres/) by [Guillermo Cruz](https://wuilly.com/).

!!! info
    In this example we use invented custom headers `X-Key` and `X-Token`.

    But in real cases, when implementing security, you would get more benefits from using the integrated [Security utilities (the next chapter)](../security/index.md){.internal-link target=_blank}.

## Dependencies errors and return values

    hashed_password = hashed_password,
)
```

!!! warning
    The supporting additional functions are just to demo a possible flow of the data, but they of course are not providing any real security.

## Reduce duplication

Reducing code duplication is one of the core ideas in **FastAPI**.
