Hi,

could someone help with with an example of how to provide a dead letter queue for my existing SQS queue:

e.g. below

service: email-integration

provider:  
name: aws  
runtime: nodejs4.3

stage: dev  
region: eu-west-1

iamRoleStatements:  
- Effect: "Allow"  
Action:  
- "sqs:_"  
Resource: "arn:aws:sqs:_:_:emailtaskqueue"  
- Effect: "Allow"  
Action:  
- "lambda:_"  
Resource: “\*”

functions:  
hello:  
handler: handler.hello  
events: # All events associated with this function  
- http:  
path: hello  
method: get

emailRequestListener:  
handler: emailRequestListener/handler.emailRequestListener  
events:  
- http:  
path: sendEmail  
method: post

emailTaskConsumer:  
handler: emailTaskConsumer/handler.emailTaskConsumer  
timeout: 200  
events:  
- schedule: rate(1 minute)

emailWorker:  
handler: emailWorker/handler.emailWorker

resources:  
Resources:  
EmailTaskDeadLetterQueue:  
Type: 'AWS::SQS::Queue’  
Properties:  
MessageRetentionPeriod: 1209600  
QueueName: emailtaskdeadletterqueue

```
EmailTaskQueue:
  Type: 'AWS::SQS::Queue'
  Properties:
    MessageRetentionPeriod: 1209600
    QueueName: emailtaskqueue
    RedrivePolicy:
        ???
```

Hey @walshe,  
I know it might be a bit late, but I see the question is unanswered and I feel compelled to collaborate.

Please serve yourself how to setup the DLQ to a lambda function straight in your yml file, the next picture will show you an example, I’ll also paste some text down below, is as simple as that.

\<your\_function\_name\>:  
handler: \<your\_handler\>  
timeout: 12  
memorySize: 576  
reservedConcurrency: 20 # optional, Overwrite the default reserved concurrency limit. By default, AWS uses account concurrency limit  
**onError: arn:aws:sns:eu-west-2:############:FailedFns # Optional SNS topic / SQS arn (Ref, Fn::GetAtt and Fn::ImportValue are supported as well) which will be used for the DeadLetterConfig**

As you can see the bolded text, the [**onError**] config attr is the way to config the DLQ for a function. You are also allowed to use CloudFormation sintax here.

I hope this helps.

Cheers!  
Hamlet
