## Репликация — процессы и память { #replication-processes-and-memory }

В приложении FastAPI, используя серверную программу (например, команду `fastapi`, которая запускает Uvicorn), запуск в **одном процессе** уже позволяет обслуживать нескольких клиентов одновременно.

Но во многих случаях вы захотите одновременно запустить несколько процессов‑воркеров.

# 擴充 OpenAPI { #extending-openapi }

有些情況你可能需要修改自動產生的 OpenAPI 結構（schema）。

本章將示範如何做。

## 一般流程 { #the-normal-process }

一般（預設）的流程如下。

`FastAPI` 應用程式（實例）有一個 `.openapi()` 方法，會回傳 OpenAPI 結構。

在建立應用物件時，會同時註冊一個 `/openapi.json`（或你在 `openapi_url` 設定的路徑）的路徑操作（path operation）。

這個路徑只會回傳一個 JSON 回應，內容就是應用的 `.openapi()` 方法結果。

預設情況下，`.openapi()` 會先檢查 `.openapi_schema` 屬性是否已有內容，有的話就直接回傳。
