KIP-1360 — Cluster Synchronous Mirroring

Discussion BrokerMirrorMaker

Introduces a synchronous cluster mirroring mode that withholds producer acknowledgment until a record has been replicated to the ISR of every registered destination cluster, extending the ISR-based ack predicate across mirroring links. Asynchronous mirroring leaves a lag-tail data-loss window where records acknowledged on the source never reach the destination before a failure, and stretched clusters do not protect against software or configuration incidents, so neither delivers a zero-RPO disaster recovery story.
