Does localstack support tumbling window from kinesis stream?

Platform
1

I am considering using Lambda with tumbling windows. However, I came across the following limitation on the Lambda resource mapping page:

• Streaming pollers for Kinesis and DynamoDB do not support features such as:
    • BisectBatchOnFunctionError
    • MaximumBatchingWindowInSeconds
    • ParallelizationFactor
    • ScalingConfig
    • TumblingWindowInSeconds

I also found another source where isaac-j-miller uses tumbling windows in this issue 7193.

Does LocalStack support tumbling windows?

Hi @kohei,

The documentation mentioned refers to the new ESMv2 version currently under development, to which we are actively adding new features.

You should be capable of performing CRUD operations with tumbling windows when using ESMv1.

Thank you, Marcel!
I apologize for my limited English skills.
By the way, is there a way to close the discussion?

@kohei You can check out our new behavior coverage for Lambda ESM v2: Lambda | Docs

Feel free to open a GitHub issue if CRUD support is insufficient and you need the correct behavior of TumblingWindowInSeconds.
