* The configuration cache serialization infrastructure should be used for all serialization.
* Existing usages of Serializer outside of this infrastructure should be migrated to use it.
* Existing usages of Java serialization should be migrated to use it.
* It is ok for Serializer to be used as a replacement for Java serialization as a migration step.

> Will an upgrade of an existing MinIO cluster impact the SLA of the cluster or will it even cause downtime?

No, an upgrade should not cause any downtime. However, on the first startup -
since MinIO will attempt to migrate any existing IAM data - the boot process may
take slightly longer, but may not be visibly noticeable. Once the migration has

  1. Any significant changes should be accompanied by tests. The project already
     has good test coverage, so look at some existing tests if you're unsure
     how to go about it.
  2. All contributions must be licensed Apache 2.0 and all files must have a
     copy of the boilerplate license comment (can be copied from an existing
     file).
  3. Files should be formatted according to Google's [Java style guide][].

Pero en algunos casos necesitas retornar un status code diferente al predeterminado.

## Casos de uso

Por ejemplo, imagina que quieres retornar un HTTP status code de "OK" `200` por defecto.

Pero si los datos no existen, quieres crearlos y retornar un HTTP status code de "CREATED" `201`.

Pero aún quieres poder filtrar y convertir los datos que retornas con un `response_model`.

Para esos casos, puedes usar un parámetro `Response`.
