DynamoDB ConsumedWriteCapacityUnits vs Consumed CloudWatch Metrics for 1 second Period

I am confused by this live chart, ConsumedWriteCapacityUnits is exceeding the provisioned units, while "consumed" is way below. Do I have a real problem or not? This seems to only show for the

One Second Period

One Minute Period

Your period is wrong for the metrics. DynamoDB emits metrics at the following periods:

ConsumedCapacity: 1 min ProvisionedCapacity: 5 min

For ConsumedCapacity you should divide the metric by the period but only at a minimum of 1min.

Exceeding provisioned capacity for short periods of time is fine, as burst capacity will allow you to do so. But if you exceed it for long periods it will lead to throttling.
