Explanation:
Delete then re-create the table
The DeleteTable operation deletes a table and all of its items. After a DeleteTable request, the specified table is in the DELETING state until DynamoDB completes the deletion.
Scan and call DeleteItem - Scan is a very slow operation for 10 million items and this is not the best-fit option for the given use-case.
Scan and call BatchDeleteItem - Scan is a very slow operation for 10 million items and this is not the best-fit option for the given use-case.
Call PurgeTable - This is a made-up option and has been added as a distractor.
