thanks @eduwercamacaro

I wrote a test that verifies that metrics are published: https://github.com/apache/kafka/pull/20570/files#diff-a8f919d43ec1cebdb136acf94adfbeb20fef0cda0ad5d29b7010e0186b355d71
I tired to run it with this change, but, unfortunately, it didn't work, and I couldn't quickly figure out why...
just a heads-up

Hi @Nikita-Shupletsov Thanks for your time checking these changes. 😄

Unfortunately, this PR contains too many changes that I need to clean up, and it is not particularly easy to follow. I am working on some cleanups to make it easier to read.

Thank you for pointing out the integration test. If possible, I'll try to make these changes pass after the cleanup.

sounds good!
please let me know if I can help

Hi @Nikita-Shupletsov
I made a new PR (#20749). In that case, the PR works more like a proposal than an experiment. Since I made this PR just as an experiment, it has too many changes that aren't needed. I’m very sorry to move this conversation.

The integration test that you mentioned was extremely useful for me to understand the problem. I copy-pasted your test in this branch and the test passes. check this change

Can you please take a look on that PR?

Thanks for your help on this. I'm trying to explore all the options to implement KIP-1035 and I believe my proposal also solves KAFKA-19434.
