AWS Lambda Function DeadLetterConfig

DeadLetterConfig is a property of the AWS::Lambda::Function resource that specifies a Dead Letter Queue (DLQ) that AWS Lambda (Lambda) sends events to when it can't process them. For example, you can send unprocessed events to an Amazon Simple Notification Service (Amazon SNS) topic, where you can take further action.
