DynamoDB Streams is a great feature that captures changes to a table at the point in time when the change happened, storing these changes in a log kept for 24hours. A second application can capture and store the information about the updates which helps to provide almost real-time and accurate usage metrics for the mobile app. DynamoDB charges for change data capture for AWS Glue Elastic Views in change data capture units. ... DynamoDB to Redshift – Using DynamoDB Streams. DynamoDB charges for reading, writing and storing data in your DynamoDB tables, and for any additional features, you choose to add.

Auto scaling starts triggering scale-up activities to increase the provisioned capacity to bring actual utilization closer to the target of 70 percent. During the third hour, assume the consumed capacity decreases to 80 RCUs and 80 WCUs, which results in an actual utilization decrease to 56 percent (80 consumed ÷ 143 provisioned), well below the target utilization of 70 percent. Users pay for a certain capacity on a given table and AWS automatically throttles any reads or writes that exceed that capacity.
