             Summary: 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


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
