I would like to specify the maximumBatchingWindow property for an SQS event. It is mentioned here in the docs, but it does not seem to work.
I am still on serverless v1, and my yaml contains something like this:
messageProcessor:
handler: com.me.MessageProcessor
timeout: 60
memorySize: 2048
reservedConcurrency: 1
events:
- sqs:
batchSize: 20 # can be larger: total pay-load cannot exceed 6MB
maximumBatchingWindow: 1 # cannot be zero
arn:
Fn::GetAtt:
- messagesQ
- Arn
But when I try to apply these settings I get this error from AWS:
Invalid request provided: Maximum batch window in seconds must be greater than 0 if maximum batch size is greater than 10 (Service: Lambda, Status Code: 400, Request ID
Which leads me to believe that the setting is ignored.
Is there some workaround I can try, or will it work only after I upgrade to v2?
I don’t have the same problem, FWIW in the latest release. I was hitting the same error initially, but it was because I’d named the property maximumBatchWindow instead of maximumBatchingWindow
For me, it was not working for serverless V1.7. I updated the serverless to 2.23 and it started working.
for V1.7 it was not picking up batchSize and maximumBatchingWindow
For V2.23 its working now and changes are reflected in aws console
