Hi all, During the implementation of KIP-460, we discovered that we had to make some minor changes to the design. I have updated the KIP wiki[1]. You can see the difference here[2].
At a high-level we made the following changes: 1. Added a top level ErrorCode to the response for errors that apply to all of the topic partitions. This is currently being used for cluster authorization errors. 2. We renamed the delayedOperation for DelayOperationPurgatory from ElectPreferredLeader to ElectLeader.
