CPU Quota, NodeStatus will contain a warning indicating that CPU Limits cannot

> 최신 파이썬 버전은 **`async` 및 `await`** 문법과 함께 **“코루틴”**이라고 하는 것을 사용하는 **“비동기 코드”**를 지원합니다.

이제 이 말을 조금 더 이해할 수 있을 것입니다. ✨

이것이 (Starlette을 통해) FastAPI를 강하게 하면서 그것이 인상적인 성능을 낼 수 있게 합니다.

## 매우 세부적인 기술적 사항

/// warning | "경고"

이 부분은 넘어가도 됩니다.

이것들은 **FastAPI**가 내부적으로 어떻게 동작하는지에 대한 매우 세부적인 기술사항입니다.

만약 기술적 지식(코루틴, 스레드, 블록킹 등)이 있고 FastAPI가 어떻게 `async def` vs `def`를 다루는지 궁금하다면, 계속하십시오.

SQLAlchemy 模型`User`包含一个`hashed_password`，它应该是一个包含散列的安全密码。

但由于 API 客户端提供的是原始密码，因此您需要将其提取并在应用程序中生成散列密码。

然后将hashed_password参数与要保存的值一起传递。

///

/// warning

此示例不安全，密码未经过哈希处理。

在现实生活中的应用程序中，您需要对密码进行哈希处理，并且永远不要以明文形式保存它们。

有关更多详细信息，请返回教程中的安全部分。

在这里，我们只关注数据库的工具和机制。

你很有可能不需要此基础镜像或任何其他类似的镜像，最好从头开始构建镜像，如[上面所述：为 FastAPI 构建 Docker 镜像](#build-a-docker-image-for-fastapi)。

///

该镜像包含一个**自动调整**机制，用于根据可用的 CPU 核心设置**worker进程数**。

它具有**合理的默认值**，但你仍然可以使用**环境变量**或配置文件更改和更新所有配置。
