**FastAPI**を使用している場合、その「最初の」関数が*path operation 関数*であり、FastAPIが正しく実行する方法を知っているので、心配する必要はありません。

しかし、FastAPI以外で `async` / `await` を使用したい場合は、<a href="https://docs.python.org/3/library/asyncio-task.html#coroutine" class="external-link" target="_blank">公式Pythonドキュメントを参照して下さい</a>。

### 非同期コードの他の形式

`async` と `await` を使用するスタイルは、この言語では比較的新しいものです。

非同期コードの操作がはるかに簡単になります。

- Add azure disk WriteAccelerator support ([#87945](https://github.com/kubernetes/kubernetes/pull/87945), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Add delays between goroutines for vm instance update ([#88094](https://github.com/kubernetes/kubernetes/pull/88094), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

* Resolves bottleneck in internal API server communication that can cause increased goroutines and degrade API Server performance ([#80465](https://github.com/kubernetes/kubernetes/pull/80465), [@answer1991](https://github.com/answer1991))
