How to set maximumBatchingWindowInSeconds for AWS SQS in serverless.yml?

Question

I have created a serverless.yml file using serverless library. I have created a lambda service and SQS Service. However I am unable set the maximum batching window property in serverless. Currently it is set to 0 and lambda is invoked with single payload.

I have tried using batchWindow property but it doesn't work.

  events:
  - sqs: 
      arn: 
        Fn::GetAtt: [ sqsQueue, Arn ]
      batchSize: 4
      batchWindow: 40

I have also tried using maximumBatchingWindowInSeconds property but still the value is 0.

  events:
  - sqs: 
      arn: 
        Fn::GetAtt: [ sqsQueue, Arn ]
      batchSize: 4
      maximumBatchingWindowInSeconds: 40

Is there a way we can do it by overriding aws cloudformation resources in serverless? https://www.serverless.com/framework/docs/providers/aws/guide/resources/#override-aws-cloudformation-resource

Answer 1

correct syntax can be found below:

events:
      - sqs:
          arn: arn:aws:sqs:region:XXXXXX:myQueue
          batchSize: 10
          maximumBatchingWindow: 60

Please make sure that you're using the latest version of the Framework.
