In Kafka, consumer group offsets are stored in a special topic (__consumer_offsets). When you replicate data to a second cluster, the consumer offsets in that cluster are not automatically in sync with the primary. MirrorMaker 2’s checkpoint connector addresses this by translating and syncing offsets periodically. Still, if a failover happens, consumers might have to seek to the translated offset positions in the new cluster. There’s a potential for confusion or even duplicate\u002Fmissed messages if the offset sync isn’t perfectly up-to-date. Confluent’s enterprise feature “Cluster Linking” improves this by preserving offsets exactly (since it effectively ships log segments over), but in open source Kafka, some manual intervention or careful planning is needed to smoothly switch consumers to a new cluster.",[342,1182,1183],{},"Topic Naming and Filtering: By default, MirrorMaker 2 will replicate all topics (or a whitelist\u002Fblacklist pattern). In multi-region architectures, it’s common to use prefixes to prevent collision or loops. For example, cluster “east” might prepend east. to all its topic names when mirroring to “west”, so on West cluster you have east.topic1 as the mirror of topic1 from East. This means consumers on the West cluster might subscribe to a different topic name. It’s a design decision: do you keep the same topic names on the secondary (and be careful to avoid feeding mirrored data back), or do you use distinct names? The Dattell comparison notes that Kafka “topics in the remote cluster must have a different name than the original” in two-way replication setups – because without that, the mirrored data would confuse the mirror maker on the return path.

For instance, Region A handles all events for customers in Americas, Region B for customers in EMEA, and they replicate to each other so both have the full global dataset read-only.

Each cluster maintains its own order per partition. During failover, consumers might observe a slight disordering around the switch (especially if some messages were in transit). In critical systems, you might implement an “event ID” to deduplicate or reorder if needed across clusters.",[342,1234,1235],{},"Schema and Metadata: Kafka doesn’t automatically replicate schema registry data or other metadata.
