Matthias J. Sax commented on KAFKA-5488:
----------------------------------------
Thanks for creating this JIRA. I agree that the index access is a little clumsy
and support the basic idea. Details to be determined. Can you do us one favor
and c&p the proposal into the JIRA itself? It's easier to tack if the ticket is
self contained and does not link to external resources.
Btw: this will require a KIP. Do you want to work on this by yourself? That
would be great. :)

> https://gitlab.com/childno.de/apache_kafka/snippets/1665655
> long story short: it's a mess to get a {{KStream<>[]}} out from
> {{KStream<>branch(Predicate<>...)}}. It breaks the fluent API and it produces
> bad code which is not that good to maintain since you have to know the right
> index for an unnamed branching stream.
> Quick idea, s.th. like {{void branch(final BranchDefinition<Predicate<>,
> Consumer<KStream<>>>... branchPredicatesAndHandlers);}} where you can write
> branches/streams code nested where it belongs to
