Dynamo db cost usage

DynamoDB does not emit table level costs, as i'm sure you have already noticed. However, in Cost Explorer we can Cost Allocation Tagging to break down the costs for each table individually.

A common way to achieve this is to tag each table with its unique name, also known as Eponymous Table Tagging. We have provided a simple tool which can help you do this for all your current tables which is available in the AWS Labs GitHub. This will traverse all of your tables and add a tag with value of TableName, which will further allow you to break costs down per table.
