Hi Konstantine, I've discovered a bug with topic IDs that can be encountered when upgrading from IBP versions below 2.8.
Since 2.8, when handling leader and isr requests, the request topic IDs are compared to the log IDs and partitions with inconsistent IDs are skipped. With a change introduced in 3.0, in some upgrade scenarios, topic IDs for existing topics will not be assigned to the logs. For topics affected with the issue, we will not be able to check the topic ID. We could potentially handle partitions with inconsistent topic IDs incorrectly. I believe this should be considered a blocker for 3.0. JIRA is here <https://issues.apache.org/jira/browse/KAFKA-13132> and PR to fix the issue here <https://github.com/apache/kafka/pull/11126>.
