**FastAPI** 提供了以下內容：

### 建立在開放標準的基礎上 { #based-on-open-standards }

* 使用 [**OpenAPI**](https://github.com/OAI/OpenAPI-Specification) 來建立 API，包含 <dfn title="也稱為：端點、路由">路徑</dfn>、<dfn title="也稱為 HTTP 方法，例如 POST、GET、PUT、DELETE">操作</dfn>、參數、請求內文、安全性等宣告。
* 使用 [**JSON Schema**](https://json-schema.org/)（因為 OpenAPI 本身就是基於 JSON Schema）自動生成資料模型文件。
* 經過縝密的研究後圍繞這些標準進行設計，而不是事後在已有系統上附加的一層功能。
* 這也讓我們在多種語言中可以使用自動**用戶端程式碼生成**。

### 能夠自動生成文件 { #automatic-docs }

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 staging committer - to take...
