releases of OkHttp are not compatible with OkHttp 3.5. When upgrading to the new package
    please note that the `WebSocket` and `WebSocketCall` classes have been merged. Sending messages
    is now asynchronous and they may be enqueued before the web socket is connected.

# 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"

### 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

- Added alpha support for asynchronous Pod preemption.
  When the `SchedulerAsyncPreemption` feature gate is enabled, the scheduler now runs API calls to trigger preemptions asynchronously for better performance. ([#128170](https://github.com/kubernetes/kubernetes/pull/128170), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling and Testing]

		if t.Replicate {
			return true
		}
	}
	return false
}

// Synchronous returns true if at least one target qualifies for synchronous replication
func (d ReplicateDecision) Synchronous() bool {
	for _, t := range d.targetsMap {
		if t.Synchronous {
			return true
		}
	}
	return false
}

func (d ReplicateDecision) String() string {
	b := new(bytes.Buffer)

- Graduated the asynchronous preemption feature in the scheduler to beta.

### Sync/Async Replication

By default, replication is completed asynchronously. If synchronous replication is desired, set the --sync flag while adding a
remote replication target using the `mc admin bucket remote add` command. For mc releases on or after `RELEASE.2022-12-24T15-21-38Z`, the 

Replication of object version and metadata

If an object meets replication rules as set in the replication configuration, `X-Amz-Replication-Status` is first set to `PENDING` as the PUT operation completes and replication is queued (unless synchronous replication is in place). After replication is performed, the metadata on the source object version changes to `COMPLETED` or `FAILED` depending on whether replication succeeded. The object version on the target shows `X-Amz-Replication-Status`...
