The first 2.5M reads per month are free, and $0.02 per 100,000 after that. Write requests for global tables are measured in replicated WCUs for provisioned capacity and replicated write request units for on-demand capacity. AWS offers DynamoDB Streams, which is a time-ordered sequence of item-level changes on a DynamoDB table. This functionality helps reduce the operational burden and complexity involved in protecting sensitive data. The cost structure for both of these AWS NoSQL databases is also different.
