Thanks for this really great tutorial! I liked it very much, these sort of step by step examples are useful for a lot of us, who tries to learn Kotlin and apply modern tech in our projects.

I am not sure, if you can do tutorials by request. But lots of us could really use a step by step guide how to use “avro4k” with Kotlin, Spring Boot, and Kafka. There are a few of around trying to explain how to use Avro and Kafka with Spring Boot. But all of them (at least what I found) wanted me to generate my value objects from schemas. Well, I don’t want that. It doesn’t feel it right to me. That’s when “avro4k” came across. But I couldn’t really get it working. I know, that’s my bad, and maybe this is why, I got really disappointed first. And then angry about it, and then I got so pissed off, that I’d just deleted even the repo in which I stored my example code… I know, it wasn’t a smart decision, but your example worked perfectly with JSON and that was good enough for me at that time.

But you know, the voices just keep telling me that, it would be better to use Avro. And then I was thinking about you have far more greater experience with Kotlin and SpringBoot then me and my likeminded friends, so probably it might not be too complicated for you. So, if you can put together a similar step by step guide for sending two type of messages to different Kafka topics using “avro4k” for serialisation, and the consume both of them in the same consumer application, using Spring Boot, that would be much appreciated!

Hello! 🙂

Thank you for such kind words!

You’re totally right, and thank you for letting me know. Consider it done.

Thanks for this really great step by step tutorial. I just want to notice that the yaml file for “Fix an infinite-loop problem” is not correct which “spring” is missing. I have also checked the github repo and it’s ok there but only in the screenshot in the 4.7 an infinite-loop problem.
