Question

A developer is creating an AWS Lambda function that searches for items from an Amazon DynamoDB table that contains customer contact information. The DynamoDB table items have the customer’s email_address as the partition key and additional properties such as customer_type, name and job_title. The Lambda function runs whenever a user types a new character into the customer_type text input. The developer wants the search to return partial matches of all the email_address property of a particular customer_type. The developer does not want to recreate the DynamoDB table. What should the developer do to meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Add a global secondary index (GSI) to the DynamoDB table with customer_type as the partition key and email_address as the sort key. Perform a query operation on the GSI by using the begins_with key condition expressio... Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling.
