Eugen Feller commented on KAFKA-7634:
-------------------------------------
Hi [~guozhang] Thanks a lot for your quick reply. I will give it a try with one
service. We have a mono repo. Changing the library in a major version would
require me to change a lot of services. I am currently using
[https://github.com/manub/scalatest-embedded-kafka] to provide embedded Kafka
for some unit tests. For others, I am using
[https://github.com/jpzk/mockedstreams], which is a wrapper around
TopologyTestDriver. Will try to use the TopologyTestDriver directly to
reproduce.
> Punctuate not being called with merge() and/or outerJoin()

> Key: KAFKA-7634
> URL: https://issues.apache.org/jira/browse/KAFKA-7634
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.11.0.3
> Reporter: Eugen Feller
> Priority: Major
>
> Hi all,
> I am using the Processor API and having trouble to get Kafka streams
> v0.11.0.3 call the punctuate() function after a merge() and/or outerJoin().
> Specifically, I am having a topology where I am doing flatMapValues() ->
> merge() and/or outerJoin -> transform(). If I dont call merge() and/or
> outerJoin() before transform(), punctuate is being called as expected.
> Thank you very much in advance for your help.
