以下代码段用 AWS SDK于 JavaScript v3。有关如何安装客户端和用法的更多信息，请参阅 Timestream Write Client-f AWS SDK or JavaScript v3。

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

const params = {
    DatabaseName: "testDbFromNode",
    KmsKeyId: updatedKmsKeyId
};

const command = new UpdateDatabaseCommand(params);

try {
    const data = await writeClient.send(command);
    console.log(`Database ${data.Database.DatabaseName} updated kmsKeyId to ${updatedKmsKeyId}`);
} catch (error) {
    if (error.code === 'ResourceNotFoundException') {
        console.log("Database doesn't exist.");
    } else {
        console.log("Update database failed.", error);
    }
}

以下代码段使用了 for AWS SDK JavaScript V2 样式。它基于 Node.js 示例 Amazon Timestream 中的示例 LiveAnalytics 应用程序，供其上使用。 GitHub
