We are in the process of creating a simple application that will compare user data to learn API Gateway, Lambda and DynamoDB. You can use query parameters to target specific resources. There is a new key, multiValueQueryStringParameters , available in the input event. Pagination is the process of returning a large set of results in chunks (or pages) to reduce the amount of information that is sent with each request.
