之后，对于你的生产应用程序，你可能会想要使用像 **PostgreSQL** 这样的数据库服务器。

/// tip | 提示

有一个使用 **FastAPI** 和 **PostgreSQL** 的官方项目生成器，其中包括了前端和更多工具： [https://github.com/fastapi/full-stack-fastapi-template](https://github.com/fastapi/full-stack-fastapi-template)

这是一个非常简单和简短的教程。如果你想了解一般的数据库、SQL 或更高级的功能，请查看 [SQLModel 文档](https://sqlmodel.tiangolo.com/)。

## 安装 `SQLModel` { #install-sqlmodel }

	queueDirComment   = `staging dir for undelivered messages e.g. '/home/events'`
	queueLimitComment = `maximum limit for undelivered messages, defaults to '100000'`
)

// Help template inputs for all notification targets
var (
	HelpWebhook = config.HelpKVS{
		config.HelpKV{
			Key:         target.WebhookEndpoint,
			Description: "webhook server endpoint e.g. http://localhost:8080/minio/events",

Tenha em mente que, como os chats permitem uma “conversa mais livre”, é fácil fazer perguntas muito gerais e mais difíceis de responder, então você pode acabar não recebendo respostas.

나중에 프로덕션 애플리케이션에서는 **PostgreSQL**과 같은 데이터베이스 서버를 사용하는 것이 좋습니다.

same way they do with HDFS. These workloads rely on HDFS atomic rename 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...
