次のスニペットは JavaScript v3 に を使用します AWS SDK。クライアントのインストール方法と使用状況の詳細については、 JavaScript 「v3 SDKの Timestream Write Client - AWS」を参照してください。

追加のコマンドのインポートがここに表示されます。クライアントの作成にはCreateDatabaseCommandインポートは必要ありません。

import { TimestreamWriteClient, CreateDatabaseCommand } from "@aws-sdk/client-timestream-write";
const writeClient = new TimestreamWriteClient({ region: "us-east-1" });

次のスニペットは JavaScript V2 スタイルに AWS SDKを使用します。これは、Node.js のサンプルアプリケーションに基づいており、 の LiveAnalytics アプリケーション用の Amazon Timestream サンプルです GitHub。

var https = require('https');
var agent = new https.Agent({
    maxSockets: 5000
});
writeClient = new AWS.TimestreamWrite({
        maxRetries: 10,
        httpOptions: {
            timeout: 20000,
            agent: agent
        }
    });  

var writeClientConfig = new AmazonTimestreamWriteConfig
{
    RegionEndpoint = RegionEndpoint.USEast1,
    Timeout = TimeSpan.FromSeconds(20),
    MaxErrorRetry = 10
};

var writeClient = new AmazonTimestreamWriteClient(writeClientConfig);
