$0.6M/Year Savings by Using S3 for ChangeDataCapture for DynamoDB Table

Moving data from the database that doesn't change, changes infrequently compared with reads, or doesn't need to be joined with other data is a surprisingly underutilised design pattern. I've found it can heavily reduce costs - particularly if in the cloud - S3/R2 and their alternatives are all much cheaper than storing and retrieving data from a cloud database.
