I have a simple kafka stream app that process input from 3 topics but no out is required since the final step is to save the processing outcome to db.

I saw this example for multiple inputs topics and that exactly what I need apart from the output binding, That is the bean should not return an output but should consume from 3 different topics as KStream,KTable and GlobalKtable and finish. Any ideas how I can change the example for my needs?

Just make it a `Consumer` instead of a `Function`. Function has input/output bindings. Consumer has only input binding and Supplier has only output binding. – Oleg Zhurakousky Aug 23 '22 at 08:59
Thank you. But How to consume from 3 different topics only? one as KStream, other KTable and the third GlobalKTable. – user1409534 Aug 23 '22 at 11:02
Something like this: `public Function, Function, Consumer>>> enrichOrder()` – Oleg Zhurakousky Aug 23 '22 at 11:54
