What it shows

  • MirrorMaker 2 synchronizes topic data, consumer offsets, and topic configs.
  • Active-Passive replication avoids circular dual-write split-brain issues.
  • Renames mirrored topics automatically with remote cluster prefixes.

The takeaway

Active-passive replication with offset translation guarantees failover readiness without data corruption.
