Question

A gaming company stores player match records in an Amazon DynamoDB table. Business rules require that each match record be automatically deleted 90 days after it is created to comply with a data retention policy, and the deletion should incur no additional write capacity charges. The team wants the least operational overhead. Which approach best meets these requirements?

Accepted Answer

Enable DynamoDB Time to Live (TTL) on an attribute that stores the record's expiration epoch timestamp.

Answer

Create a scheduled AWS Lambda function that scans the table daily and issues DeleteItem calls for records older than 90 days.

Answer

Configure an S3 Lifecycle rule to expire objects after 90 days and export the table to S3 nightly.

Answer

Enable DynamoDB point-in-time recovery and restore the table every 90 days to drop old records.
