We'll start with DynamoDB. And I want to start with what is the atomic unit of scaling that we use? With the DynamoDB table, the partition is going to be that atomic unit for performance and scaling, and then we can have as little as one read or write operation per table provisioned. And the higher that number goes, it's going to be based on the number of partitions we're actually using, which is the result of an equation that includes the amount of data in the table.
