KIP-595 —  A Raft Protocol for the Metadata Quorum

Accepted Kafka 2.7 KRaftProtocol

Defines a Kafka-native Raft consensus protocol (`KRaft`) for the cluster metadata quorum, adapting Kafka's existing leader-follower log replication to support leader election, epoch tracking, and linearizable reads without ZooKeeper. This is the core protocol layer underpinning KIP-500's goal to eliminate ZooKeeper from Kafka's control plane.
