# 並行処理と async / await

*path operation 関数*のための `async def` に関する詳細と非同期 (asynchronous) コード、並行処理 (Concurrency)、そして、並列処理 (Parallelism) の背景について。

次のような、`await` を使用して呼び出すべきサードパーティライブラリを使用している場合:

```Python
results = await some_library()
```

以下の様に `async def` を使用して*path operation 関数*を宣言します。

```Python hl_lines="2"
@app.get('/')

### DELETE operation in REST API

	// Empty fi.VersionID indicates that versioning is either
	// suspended or disabled on this bucket. RenameData will replace
	// the 'null' version. We add a free-version to track its tiered
	// content for asynchronous deletion.
	//
	// Note: RestoreObject and HealObject requests don't end up replacing the
	// null version and therefore don't require the free-version to track
	// anything

* Update k8s.io/utils to allow for asynchronous process control ([#71047](https://github.com/kubernetes/kubernetes/pull/71047), [@hoegaarden](https://github.com/hoegaarden))

  For more information, see [#56357](https://github.com/kubernetes/kubernetes/issues/56357).

*   Audit logging is slow because writes to the log are performed synchronously with requests to the log. This issue will be fixed in a future release.

  For more information, see [#53006](https://github.com/kubernetes/kubernetes/issues/53006).
