Dennis Reiter commented on KAFKA-7445:
--------------------------------------
[~mjsax]: Thanks for the hint! I will give it a try.
[~guozhang]: I didn't want to change the branching logic, just using it as an
example.
> Branch one Stream in multiple Streams

> Key: KAFKA-7445
> URL: https://issues.apache.org/jira/browse/KAFKA-7445
> Project: Kafka
> Issue Type: New Feature
> Components: streams
> Reporter: Dennis Reiter
> Priority: Minor
>
> Hi,
> I need to branch/split KStreams in multiple independent KStreams. I thought,
> {{org.apache.kafka.streams.kstream.internals.KStreamImpl#branch}} is the
> right one but in fact, its designed for another purpose.
> In contrast to {{branch}} I need to assign the record to *all* matching
> streams, not only one stream.
> Speaking in code
> ({{org.apache.kafka.streams.kstream.internals.KStreamBranch}}):
> {code:java}
> if (predicates[i].test(key, value)) {
> // use forward with childIndex here
> // and pipe the record to multiple streams
> context().forward(key, value, i);
> }
> {code}
> My question: is this still possible with features already included in
> Streams? Or shall I propose a change?
> Thanks in advance
> Dennis
