dajac opened a new pull request, #12240: URL: https://github.com/apache/kafka/pull/12240
This PR implements a first part of [KIP-841](https://cwiki.apache.org/confluence/display/KAFKA/KIP-841%3A+Fenced+replicas+should+not+be+allowed+to+join+the+ISR+in+KRaft). Specifically, it implements the following: * Adds a new metadata version. * Adds the InControlledShutdown field to the BrokerRegistrationRecord and BrokerRegistrationChangeRecord and bump their versions. The newest versions are only used if the new metadata version is enabled. * Writes a BrokerRegistrationChangeRecord with InControlledShutdown set when a broker requests a controlled shutdown. * Ensures that fenced and in controlled shutdown replicas are not picked as leaders nor included in the ISR. * Adds or extends unit tests. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
