Eugen Feller commented on KAFKA-7634:
-------------------------------------
Sure, let me try what I can do. Code looks like this:
{code:java}
val table =
bldr
.table[Key, Value1](
keySerde,
valueSerde1,
topicA,
stateStoreName
)
val stream1 =
bldr
.stream[Key, Value2](
keySerde,
valueSerde2,
topicB
)
.filterNot((k: Key, s: Value2) => s == null)
val enrichedStream = stream1
.leftJoin[Value1, Value3](
table,
joiner,
keySerde,
valueSerde2
)
val explodedStream =
bldr
.stream[Mac, Value4](
keySerde,
valueSerde4,
topicC
)
.flatMapValues[Value3]()
val mergedStream = bldr.merge[Key, Value3](enrichedStream, explodedStream)
mergedStream.transform[Key, Value3](transformer).to(keySerde, valueSerde3,
outputTopic){code}
> Punctuate not being called with merge() and/or outerJoin()

> 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.
