6 - DynamoDB

DynamoDB is a fully managed proprietary NoSQL database service that supports key-value and document data structures and is offered by Amazon as part of the Amazon Web Services portfolio. Amazon CloudWatch aggregates the DynamoDB metrics at one-minute intervals.

In DynamoDB, provisioned throughput requirements are specified in terms of capacity units: Read Capacity unit and Write Capacity unit. A unit of read capacity represents one strongly consistent read per second for items up to 4 KB in size. One write capacity unit represents one write per second for items up to 1 KB in size. Larger items will require more capacity. You can calculate the number of units of read and write capacity by estimating the number of reads or writes required per second and multiplying by the size of the items rounded up to the nearest KB.

For more information, see the Amazon DynamoDB documentation.

aws.dynamodb.ConsumedWriteCapacityUnits

The amount of write capacity units consumed over the specified time interval. Amazon CloudWatch aggregates the metrics at one-minute intervals. Use the Sum aggregation to calculate the consumed throughput.
