Nexmark performance test - Realtime Compute for Apache Flink - Alibaba Cloud ドキュメントセンター

このトピックでは、Nexmark を使用して Realtime Compute for Apache Flink のパフォーマンスをテストする方法について説明します。

パフォーマンス

Realtime Compute for Apache Flink で 1 計算ユニット (CU) の計算リソース構成を使用した場合、19 の Nexmark クエリのパフォーマンスは、最小で 5,000 レコード/秒 (RPS) から最大で 55,000 RPS の範囲になります。

単一ストリームのフィルタリングや文字列変換などの単純な操作の場合、1 CU で 1 秒あたり 40,000 から 55,000 レコードを処理できます。
JOIN、GROUP BY、ウィンドウ関数操作などの複雑な操作の場合、1 CU で 1 秒あたり 5,000 から 10,000 レコードを処理できます。

前提条件

Java 開発キット (JDK) 1.8.x 以降のバージョンがインストールされている必要があります。
Maven 3.8.2 がインストールされています。
Git がインストールされている必要があります。Git をダウンロードするには、Git をご参照ください。
Nexmark がインストールされています。Nexmark の詳細については、「Nexmark」をご参照ください。
ワークスペースが作成されている必要があります。詳細については、「Realtime Compute for Apache Flink のアクティブ化」をご参照ください。
説明
Nexmark と Git はサードパーティの Web サイトです。アクセスが遅延したり、失敗したりする場合があります。

テストツール

测试图片

Nexmark ソーステーブル：テストに必要なトランザクション/秒 (TPS) に基づいてテストデータを生成します。
変換：Nexmark の 19 のクエリ。
Blackhole 結果テーブル：上流および下流のストレージによるパフォーマンスへの影響を除外し、Flink のパフォーマンスのテストに焦点を当てます。

データ準備

コマンドラインインターフェイス (CLI) で次のコマンドを実行して、Nexmark のソースコードをダウンロードし、コンパイルします。
```
cd <path>
git clone https://github.com/nexmark/nexmark.git
cd nexmark/nexmark-flink
mvn clean package
```
説明
<path> は、nexmark.git ファイルが格納されるカスタムパスを指定します。
Nexmark コネクタを作成します。
1. Realtime Compute for Apache Flink コンソールにログインします。
2. 対象のワークスペースの [操作] 列で、[コンソール] をクリックします。
3. [コネクタ]ページの右側で、[カスタムコネクタの作成]をクリックします。
4. 表示されるダイアログボックスで、[ファイルの選択] をクリックします。次の図に例を示します。
  説明
  パッケージは `/nexmark/nexmark-flink/target` ディレクトリにあります。nexmark-flink-0.2-SNAPSHOT.jar ファイルがコンパイル済みのパッケージです。
5. [次へ] をクリックし、次に [完了] をクリックします。

次の表に、Nexmark コネクタのパラメーターを示します。

パラメーター	パラメーター値	説明
first-event.rate	10000000	データ生成レート。
next-event.rate	10000000	データ生成レート。
events.num	100000000	生成するイベントの数。
bid.proportion	92%	Bid イベントの割合。
auction.proportion	6%	Auction イベントの割合。
person.proportion	2%	Person イベントの割合。

テスト手順

次のクエリジョブを作成します。ジョブの作成方法の詳細については、「ジョブ開発マップ」をご参照ください。
