-------------------------------------------
Parent: KAFKA-12521
Issue Type: Sub-task (was: Improvement)
> Expand AdjustStreamThreadCountTest
> ----------------------------------
>
> Key: KAFKA-12506
> URL: https://issues.apache.org/jira/browse/KAFKA-12506
> Project: Kafka
> Issue Type: Sub-task
> Components: streams, unit tests
> Reporter: A. Sophie Blee-Goldman
> Priority: Major
> Labels: newbie, newbie++
>
> Right now the AdjustStreamThreadCountTest runs a minimal topology that just
> consumes a single input topic, and doesn't produce any data to this topic.
> Some of the complex concurrency bugs that we've found only showed up when we
> had some actual data to process and a stateful topology:
> [KAFKA-12503|https://issues.apache.org/jira/browse/KAFKA-12503] KAFKA-12500
> We should try to expand the Streams application in this test to really flex
> the feature. Imo this would include
> # Produce some data to the input topic
> # One or more stateful operators in the topology, with caching enabled
> # A repartition to get multiple subtopologies
> # Write out some results to an output topic
> # Verify that these results show up in the output
