### Creating the `Settings` only once with `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then reuse the same settings object, instead of reading it for each request.

But every time we do:

```Python
Settings()
```

```

A única opção nova aqui é `--workers` informando ao Uvicorn para iniciar 4 processos de trabalho.

Você também pode ver que ele mostra o **PID** de cada processo, `27365` para o processo pai (este é o **gerenciador de processos**) e um para cada processo de trabalho: `27368`, `27369`, `27370` e `27367`.

## Conceitos de Implantação { #deployment-concepts }

For example, this is not allowed:

```Python
q: Annotated[str, Query(default="rick")] = "morty"
```

...because it's not clear if the default value should be `"rick"` or `"morty"`.

So, you would use (preferably):

```Python
q: Annotated[str, Query()] = "rick"
```

...or in older code bases you will find:

```Python

sitemap1.xml http://www.example.com/ 2005-01-01 monthly 0.8 http://www.example.com/catalog?item=12&desc=vacation_hawaii weekly http://www.example.com/catalog?item=73&desc=vacation_new_zealand 2004-12-23 weekly http://www.example.com/catalog?item=74&desc=vacation_newfoundland 2004-12-23T18:00:15+00:00 0.3 http://www.example.com/catalog?item=83&desc=vacation_usa 2004-11-23...

Наприклад, цей варіант є некоректним:

```Python
q: Annotated[str, Query(default="rick")] = "morty"
```

...тому, що не зрозуміло, яке значення має бути значенням за замовчуванням: `"rick"` чи `"morty"`.

Коректні варіанти:

```Python
q: Annotated[str, Query()] = "rick"
```

...або у старих кодових базах Ви знайдете:

```Python

    /**
     * This is really just for {@link jcifs.smb1.UniAddress}. It does
     * not throw an {@link java.net.UnknownHostException} because this
     * is queried frequently and exceptions would be rather costly to
     * throw on a regular basis here.
     *
     * @param host the hostname to resolve
     * @return the resolved NbtAddress or null if not found
