检查 DynamoDB 表的当前热吞吐量 - Amazon DynamoDB

检查 DynamoDB 表的当前热吞吐量

使用以下 AWS CLI 和 AWS 管理控制台说明来检查表或索引的当前热吞吐量值。

要使用 DynamoDB 控制台检查 DynamoDB 表的热吞吐量，请执行以下操作：

  1. 登录 AWS Management Console，并打开 DynamoDB 控制台：https://console.aws.amazon.com/dynamodb/。

  2. 在左侧导航窗格中，选择 表。

  3. 在表页面上，选择所需的表。

  4. 选择其它设置以查看您当前的热吞吐量值。此值显示为每秒读取单位数和每秒写入单位数。

以下 AWS CLI 示例向您展示如何检查 DynamoDB 表的热吞吐量。

  1. 对 DynamoDB 表运行 describe-table 操作。

    aws dynamodb describe-table --table-name GameScores

  2. 您将收到与以下内容类似的响应。您的 WarmThroughput 设置将显示为 ReadUnitsPerSecond 和 WriteUnitsPerSecond。当热吞吐量值正在更新时，Status 将为 UPDATING，当设置了新的热吞吐量值时，则为 ACTIVE。
