Si vous avez une version plus ancienne, vous obtiendrez des erreurs en essayant d'utiliser `Annotated`.

Assurez-vous de [Mettre à jour la version de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} à la version 0.95.1 à minima avant d'utiliser `Annotated`.

## Déclarer des métadonnées

The `--reload` option consumes much more resources, is more unstable, etc.

It helps a lot during **development**, but you **shouldn't** use it in **production**.

///

## Deployment Concepts

These examples run the server program (e.g Uvicorn), starting **a single process**, listening on all the IPs (`0.0.0.0`) on a predefined port (e.g. `80`).

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.

Make sure you [Upgrade the FastAPI version](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

### Import `Depends`

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

Wenn Sie eine ältere Version haben, werden Sie Fehler angezeigt bekommen, wenn Sie versuchen, `Annotated` zu verwenden.

Bitte [aktualisieren Sie FastAPI](../deployment/versions.md#upgrade-der-fastapi-versionen){.internal-link target=_blank} daher mindestens zu Version 0.95.1, bevor Sie `Annotated` verwenden.

///

## Metadaten deklarieren

Если вы используете более старую версию, вы столкнётесь с ошибками при попытке использовать `Annotated`.

Убедитесь, что вы [обновили версию FastAPI](../deployment/versions.md#fastapi_2){.internal-link target=_blank} как минимум до 0.95.1 перед тем, как использовать `Annotated`.

///

## Определите метаданные

Вы можете указать все те же параметры, что и для `Query`.

		// with > 0 content-length in the body,
		// we should skip such clients and allow
		// blindly such insecure clients only if
		// S3 strict compatibility is disabled.

		// We return true only in situations when
		// deployment has asked MinIO to allow for
		// such broken clients and content-length > 0.
		return r.ContentLength > 0 && !globalServerCtxt.StrictS3Compat
	}
	return false
}

// Returns SHA256 for calculating canonical-request.

Agora que sabemos a diferença entre os termos **processo** e **programa**, vamos continuar falando sobre implantações.

- Erasure set is a single erasure coding unit within a MinIO deployment. An object is sharded within an erasure set. Erasure set size is automatically calculated based on the number of drives. MinIO supports unlimited number of drives but each erasure set can be upto 16 drives and a minimum of 2 drives.
