Их тяжелее настраивать, также им нужен брокер сообщений наподобие RabbitMQ или Redis, но зато они позволяют вам запускать фоновые задачи в нескольких процессах и даже на нескольких серверах.

Для примера, посмотрите [Project Generators](../project-generation.md){.internal-link target=_blank}, там есть проект с уже настроенным Celery.

## Casos de Uso

Alguns casos de uso incluem:

* Converter requisições não-JSON para JSON (por exemplo, <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Descomprimir corpos de requisição comprimidos com gzip.
* Registrar automaticamente todos os corpos de requisição.

## Manipulando codificações de corpo de requisição personalizadas

## Características Adicionales

Hay algunas características adicionales para manejar la seguridad además de las que se tratan en el [Tutorial - Guía de Usuario: Seguridad](../../tutorial/security/index.md){.internal-link target=_blank}.

/// tip | Consejo

Las siguientes secciones **no necesariamente son "avanzadas"**.

Y es posible que para tu caso de uso, la solución esté en alguna de ellas.
