Function consumedReadCapacityUnits

The number of read capacity units consumed over the specified time period, so you can track how much of your provisioned throughput is used. You can retrieve the total consumed read capacity for a table and all of its global secondary indexes, or for a particular global secondary index. For more information, see Provisioned Throughput in Amazon DynamoDB.

Note: Use the Sum statistic to calculate the consumed throughput. For example, get the Sum value over a span of one minute, and divide it by the number of seconds in a minute (60) to calculate the average ConsumedReadCapacityUnits per second (recognizing that this average will not highlight any large but brief spikes in read activity that occurred during that minute). You can compare the calculated value to the provisioned throughput value you provide DynamoDB.

Units: Count

Dimensions: TableName, GlobalSecondaryIndexName

Valid Statistics:

• Minimum – Minimum number of read capacity units consumed by any individual request to the table or index.
• Maximum – Maximum number of read capacity units consumed by any individual request to the table or index.
• Average – Average per-request read capacity consumed.
• Sum – Total read capacity units consumed. This is the most useful statistic for the ConsumedReadCapacityUnits metric.
• SampleCount – Number of requests to DynamoDB that consumed read capacity.
