Question

A company has a mobile chat application with a data store based in Amazon DynamoDB. Users would like new messages to be read with as little latency as possible. A solutions architect needs to design an optimal solution that requires minimal application changes. Which method should the solutions architect select?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Configure Amazon DynamoDB Accelerator (DAX) for the new messages table. Update the code to use the DAX endpoint. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. DynamoDB Accelerator (DAX) adds an in-memory cache for microsecond DynamoDB reads. AWS Config tracks resource configuration changes and evaluates compliance.
