Question

A developer is creating an AWS Step Functions state machine to handle an order processing workflow. When the state machine receives an order, the state machine pauses until the order has been confirmed. A record that is added to an Amazon DynamoDB table by another service confirms each order. The developer must complete the order processing workflow. Which solution will meet this requirement?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Update the state machine to query the DynamoDB table by using the DynamoDB GetItem state to determine whether a record exists. If the record does exist, continue to the next state. If the record does not exist, wait 5... Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling.
