Sophie Blee-Goldman commented on KAFKA-10366:
---------------------------------------------
Yeah thanks for tracking that down [~mjsax]. I think we can
repurpose/reinterpret this ticket to track fixing the Streams tests/test utils.
If we have to add a lot of overloads throughout the call hierarchy between the
test and the actual Consumer creation, maybe we can save some work by just
adding a ConsumerParameters class (better names welcome) and replacing the
ConsumerConfig/Properties parameter in all the methods instead. Then we can
just call the appropriate Consumer constructor based on whether the
deserializers have been set in the passed in. ConsumerParameters
> TimeWindowedDeserializer doesn't allow users to set a custom window size

> Related to [KAFKA-4468|https://issues.apache.org/jira/browse/KAFKA-4468], in
> timeWindowedDeserializer Long.MAX_VALUE is used as _windowSize_ for any
> deserializer that uses the default constructor. While streams apps can pass
> in a window size in serdes or while creating a timeWindowedDeserializer, the
> deserializer that is actually used in processing the messages is created by
> the Kafka consumer, without passing in the set windowSize. The deserializer
> the consumer creates uses the configs, but as there is no config for
> windowSize, the window size is always default.
> See _KStreamAggregationIntegrationTest #ShouldReduceWindowed()_ as an example
> of this issue. Despite passing in the windowSize to both the serdes and the
> timeWindowedDeserializer, the window size is set to Long.MAX_VALUE.
