Paul Snively commented on KAFKA-9636:
-------------------------------------
John,
Yep, please go ahead and close it.
Understood and agreed re: `ByteBuffer`. Maybe a future version of Kafka could
take `ByteBuffer`s for `SerDe`s instead of byte arrays?
Here's hoping the Scala API coverage for `TopologyTestDriver` etc. does get
extended at some future date. :)
Thanks once again for all your help!
> Simple join of two KTables fails
> --------------------------------

> Key: KAFKA-9636
> URL: https://issues.apache.org/jira/browse/KAFKA-9636
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.4.1
> Reporter: Paul Snively
> Assignee: John Roesler
> Priority: Major
> Attachments: merge_issue.zip

>
> Attempting to join two KTables yields a `Topology` that, when tested with
> `TopologyTestDriver` by adding records to the two `TestInputTopic`s, results
> in an empty `TestOutputTopic`.
> I'm attaching a very small reproduction. The code is in Scala. The project is
> therefore an "sbt" project. You can reproduce the results from your shell
> with `sbt test`. The failure output will include the `describe` of the
> `Topology` in question.
