Function consumedWriteCapacityUnits

The number of write 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 write 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 ConsumedWriteCapacityUnits per second (recognizing that this average will not highlight any large but brief spikes in write 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 write capacity units consumed by any individual request to the table or index.
• Maximum – Maximum number of write capacity units consumed by any individual request to the table or index.
• Average – Average per-request write capacity consumed.
• Sum – Total write capacity units consumed. This is the most useful statistic for the ConsumedWriteCapacityUnits metric.
• SampleCount – Number of requests to DynamoDB that consumed write capacity.
