では、ニワトリと卵の話のように、最初の `async` 関数はどう呼ぶのでしょうか？

**FastAPI** を使っている場合は心配ありません。その「最初の」関数は *path operation 関数* で、FastAPI が適切に実行してくれます。

しかし、FastAPI を使わずに `async` / `await` を使いたい場合もあります。

### 自分で async コードを書く { #write-your-own-async-code }

	n := int(lo) // lo = len(b) * count

	if len(b) == 0 {
		return []byte{}
	}

	// Past a certain chunk size it is counterproductive to use
	// larger chunks as the source of the write, as when the source
	// is too large we are basically just thrashing the CPU D-cache.
	// So if the result length is larger than an empirically-found
	// limit (8KB), we stop growing the source string once the limit

* New federation deployment mechanism now allows non-GCP clusters. ([#34620](https://github.com/kubernetes/kubernetes/pull/34620), [@madhusudancs](https://github.com/madhusudancs))
     * Writes the federation kubeconfig to the local kubeconfig file.

- Changed handling of `CustomResourceDefinitions` with unrecognized formats. Writing a schema with an unrecognized format now triggered a warning (the write was still accepted). ([#133136](https://github.com/kubernetes/kubernetes/pull/133136), [@yongruilin](https://github.com/yongruilin))

 * Manually using `StringBuilder` to assemble these components is cumbersome: do '+' characters get
 * silently replaced with spaces? If a query parameter contains a '&', does that get escaped?
 * By offering methods to read and write individual query parameters directly, application
 * developers are saved from the hassles of encoding and decoding.

 * ### Plus a modern API

users must manually remove this flag from their `kubelet` configuration to prevent startup failures before upgrading `kubelet`. For `kubeadm` clusters, if users pass extra arguments to the `kubelet` like `--pod-infra-container-image`, it will be written to the `kubelet` env file during the `init` phase. `kubeadm` does not remove it during the `init` or `join` phase, so users must manually remove it from `extraArgs` in the `kubelet` configuration file. ([#133779](https://github.com/kubernetes/kub...
