1. The document discusses various options for implementing disaster recovery and high availability with Kafka across multiple data centers, including MirrorMaker, MirrorMaker 2, and stretch clusters. 2. MirrorMaker provides basic asynchronous replication between data centers but has limitations around failover and latency. MirrorMaker 2 and replicators support active-active production in both DCs but with more complexity. 3. Stretch clusters treat the multiple DCs as a single Kafka cluster with synchronous replication and no producer latency, but require more resources and rely on low WAN latency. The best option depends on requirements for developer ease, latency, consistency, and budget.
