Hey folks, I'm quite confused here. I have a random partition that has 4 replications instead of 3. I don't have a clue how to fix it or what the ramifications of this are either. There are no repartitioning happening or reassignments or anything at all. This looks like the metadata is just wrong. That node 38 id on that partition shouldn't have existed at all. Can somebody tell me what's going on here? Do I have to worry? How do I fix it? What do I need to worry about with the inconsistency here? How will stores be affected? Etc? This is on a kafka 3.6.2 cluster using kraft servers.
