Is it a typical use case to enrich a topic using the contents of another topic and then publishing those to an output topic? Ie can you put reference data in a topic that’s then use to enrich messages that you are processing?

So, let's say I would like to do the following - out of 10 mil records, containing JSON values, I need to gather only one value, let's say "name" and only distinct one, how can I do this using Kafka streams? From the tutorial here I only understand that I can copy and paste ready-made code, which does not have much of a use for me since I don't understand what is inside of it and how it is working, and have no idea how to make code that will do the described task. Btw, most of the official confluent tutorials like that - no explanation of what's going on, so, mostly useful only in large quantities, like learning a language by listening to surrounding people instead of having a dictionary at hand.

With all due respect, this video is kind of useless. Would be almost the same as put a Voice Assistant to read the text from that URL. Just copy and paste without any explanation at all.
