Question $8$

A customer has written an application that uses Amazon S$3$ exclusively as a data store. The

application works well until the customer increases the rate at which the application is updating

information. The customer now reports that outdated data occasionally appears when the application

accesses objects in Amazon S$3.$ What could be the problem, given that the application logic is

otherwise correct?

The application is reading parts of objects from Amazon S$3$ using a range header.

The application is reading objects from Amazon $53$ using parallel object requests.

The application is updating records by writing new objects with unique keys.

The application is updating records by overwriting existing objects with the same keys.
