KIP-1014 — Managing Unstable Features in Apache Kafka

Discussion Kafka 3.7 Broker

KIP-1014 introduces an "unstable feature" framework for Apache Kafka where in-progress features are gated behind a feature flag and isolated from production traffic until fully complete and stabilized. Large features developed across many PRs produce a cluster in a partially implemented state where incompatible RPC or metadata record changes can break mixed-version clusters or expose unfinished functionality to users.
