functionality to complete writing data to the datastore. Object storage operations are atomic by nature and they do not require/implement rename API. The default S3A committer emulates renames through copy and delete APIs. This interaction pattern causes significant loss of performance because of the write amplification. _Netflix_, for example, developed two new staging committers - the Directory staging committer and the Partitioned staging committer - to take full advantage of native object storage...

Клиент получит **500 Internal Server Error** для этого запроса, но приложение продолжит работать для последующих запросов, а не «упадёт» целиком.

### Большие ошибки — падения { #bigger-errors-crashes }

Тем не менее возможны случаи, когда код **роняет всё приложение**, приводя к сбою Uvicorn и Python. 💥

O cliente receberá um **Erro Interno do Servidor 500** para essa solicitação, mas o aplicativo continuará funcionando para as próximas solicitações em vez de travar completamente.

### Erros maiores - Travamentos { #bigger-errors-crashes }

No entanto, pode haver casos em que escrevemos algum código que **trava todo o aplicativo**, fazendo com que o Uvicorn e o Python travem. 💥

	// the format is explicitly chosen.
	// This ensures nominal usage of WriteHeader (without specifying the format)
	// does not always result in the PAX format being chosen, which
	// causes a 1KiB increase to every header.
	if tw.hdr.Format == FormatUnknown {
		tw.hdr.ModTime = tw.hdr.ModTime.Round(time.Second)
		tw.hdr.AccessTime = time.Time{}
		tw.hdr.ChangeTime = time.Time{}
	}

Example:

```sh
export MINIO_DOMAIN=mydomain.com
minio server /data
```

		erasureSet, ok := poolInfo[d.SetIndex]
		if !ok {
			erasureSet.ID = d.SetIndex

				dataUsageInfo := cache.dui(dataUsageRoot, nil)
				erasureSet.ObjectsCount = dataUsageInfo.ObjectsTotalCount
				erasureSet.VersionsCount = dataUsageInfo.VersionsTotalCount

Il offre :

- Des performances vraiment impressionnantes.
- Le support des WebSockets.
- Le support de GraphQL.
- Les tâches d'arrière-plan.
- Les événements de démarrage et d'arrêt.
- Un client de test basé sur request.
- CORS, GZip, fichiers statiques, streaming des réponses.
- Le support des sessions et des cookies.

El cliente obtendrá un **500 Internal Server Error** para ese request, pero la aplicación continuará funcionando para los siguientes requests en lugar de simplemente colapsar por completo.

### Errores Mayores - Colapsos { #bigger-errors-crashes }

Sin embargo, puede haber casos en los que escribamos algún código que **colapse toda la aplicación** haciendo que Uvicorn y Python colapsen. 💥
