When something goes wrong, DLQ saves the event information. Update: both AWS::IAM::Role and AWS::Lambda::Function now support custom names. According to AWS , Amazon SQS supports dead-letter queues, which other queues (source queues) can target for messages that cannot be processed (consumed) successfully. If you want to refer to these properties in an intrinsic function such as Ref or Fn::GetAtt, you can append. When the message cannot be handled properly in the Lambda function it can be passed to the DLQ and from there a separate function can handle it, e. Since AWS Lambda DLQ functionality is only available for asynchronous event sources like Amazon S3, Amazon SNS, AWS IoT or direct asynchronous invocations, and not for streaming event sources such as Amazon Kinesis or Amazon DynamoDB streams; our first step is to break this Lambda function into two functions.
