Question

A developer maintains a critical business application that uses Amazon DynamoDB as the primary data store. The DynamoDB table contains millions of documents and receives 30-60 requests each minute. The developer needs to perform processing in near-real time on the documents when they are added or updated in the DynamoDB table. How can the developer implement this feature with the LEAST amount of change to the existing application code?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Enable a DynamoDB stream on the table. Invoke an AWS Lambda function to process the documents. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. This option meets the real-time / low-latency performance requirement.
