KIP-46 — Self Healing Kafka

Discussion Broker

KIP-46 proposes automatic replica reassignment when a broker fails, detecting that redundancy has dropped below the replication factor and triggering a reassignment to surviving brokers without operator intervention. In the absence of this automation, a broker failure with replication factor 2 leaves partitions with a single replica, and restoring redundancy requires a manual `kafka-reassign-partitions.sh` invocation.
