[All AWS Certified Database - Specialty Questions]

A company is concerned about the cost of a large-scale, transactional application using Amazon DynamoDB that only needs to store data for 2 days before it is deleted. In looking at the tables, a Database Specialist notices that much of the data is months old, and goes back to when the application was first deployed.
What can the Database Specialist do to reduce the overall cost?

A. Create a new attribute in each table to track the expiration time and create an AWS Glue transformation to delete entries more than 2 days old.
B. Create a new attribute in each table to track the expiration time and enable DynamoDB Streams on each table.
C. Create a new attribute in each table to track the expiration time and enable time to live (TTL) on each table.
D. Create an Amazon CloudWatch Events event to export the data to Amazon S3 daily using AWS Data Pipeline and then truncate the Amazon DynamoDB table.

My opinion: You can include AWS glue to write a Deletion job to transform the data. TTL might be bound by the timefactor in the document

I don't think your solution helps to minimize the total cost of ownership, the delete queries will scan the tables we will need to pay for that, and we will need to pay for Glue Jobs executions and aws says "...TTL is provided at no extra cost as a means to reduce stored data volumes.."
