Hey @gonzalobertomeu, thanks for reporting your problem.
Could you elaborate on the advantages of exposing such configuration feature ? What is your use case for extending batchingWindow ?
In the meantime, you can easily override this property without a dedicated option on the construct using the Resources.extensions
property from Serverless framework:
resources:
extensions:
MyFunctionEventSourceMapping: // Replace with the actual logicalId of your event source mapping from cloudformation ressources tab
Properties:
MaximumBatchingWindowInSeconds: 150 // Whatever value fits your need

Thank you!

Hi @fredericbarthelet. Thanks for answer quickly!
In my case, I need to reduce the delay between the arrival of the message and lambda being triggered (with a standard queue).
I set a batch size of 10, but I don't always get a batch of 10 messages and have to wait 60 seconds to fill the batch window (AWS default) for the lambda to trigger.
I am using this in a messaging system (more simmilar to an email than a chat) for an educational platform, in which a message can be delivered to a single person, a family or the entire community of this school (among other categories).
60 seconds of delay its a high value for this case.
Now i'm going to try solution that you provided!

Hi @gonzalobertomeu, we recently release a new version of Lift with the introduction of the extensions property. Lift extensions allows developper to override specific pieces of CloudFormation generated by Lift constructs. This would remove the need from your side to manually input generated logicalId by CDK. Would you like to give it a try :) ?
I'm closing this issue in the meantime. Thanks
