KIP-1279 — Cluster Mirroring

Discussion MirrorMakerBroker

Cluster Mirroring introduces native broker-side cross-cluster replication as a built-in Kafka feature, replacing the need for external MirrorMaker 2 (MM2) Connect workers. MM2's standalone deployment model creates significant operational burden—separate provisioning, independent lifecycle management, and redundant compression/decompression overhead—which this KIP eliminates by integrating replication directly into brokers.
