Optionally supports custom metadata, tags and other retention settings. All objects are also readable independently once upload is completed via the regular S3 [GetObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html) API.

Además de tipos singulares normales como `str`, `int`, `float`, etc., puedes usar tipos singulares más complejos que heredan de `str`.

Para ver todas las opciones que tienes, revisa el <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Overview de Tipos de Pydantic</a>. Verás algunos ejemplos en el siguiente capítulo.

为此，请使用 Python 标准类型提示 <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>：

/// note | 笔记

定义 <a href="https://docs.pydantic.dev/latest/concepts/types/#unions" class="external-link" target="_blank">`Union`</a> 类型时，要把详细的类型写在前面，然后是不太详细的类型。下例中，更详细的 `PlaneItem` 位于 `Union[PlaneItem，CarItem]` 中的 `CarItem` 之前。

Follow below steps to get started with MinIO monitoring using Prometheus.

### 1. Download Prometheus

[Download the latest release](https://prometheus.io/download) of Prometheus for your platform, then extract it

```sh
tar xvfz prometheus-*.tar.gz
cd prometheus-*
```

// This makes it easy to run the TestServer from any of the tests.
// Using this interface, functionalities to be used in tests can be
// made generalized, and can be integrated in benchmarks/unit tests/go check suite tests.
type TestErrHandler interface {
	testing.TB
}

const (
	// ErasureSDStr is the string which is used as notation for Single node ObjectLayer in the unit tests.
	ErasureSDStr string = "ErasureSD"

This is available only on MinIO as an extension to the Expiration feature. The following rule makes it possible to remove all versions of an object under 
the prefix `user-uploads/` as soon as the latest object satisfies the expiration criteria. 

> NOTE: If the latest object is a delete marker then filtering based on `Filter.Tags` is ignored and 
> if the DELETE marker modTime satisfies the `Expiration.Days` then all versions of the object are
