KStream send record to multiple streams (not Branch)

Question

Is there a way to make branch-like operation but to place record in each output stream which predicate evaluates to true? Brach puts record to first match (documentation: A reco

Answer 1

You can "broadcast" and filter each stream individually:

KStream stream = ...

stream1 = stream.filter(...);
stream2 = stream.filter(...);
// and so on...

If you use stream variable multiple times, all records are broadcasted to all downstream filters (or any other operator), ie, each filter is executed for each record.
