This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

MirrorMaker 2.0 (also known as MM2), built using the Kafka Connect framework, solves many tool shortcomings of previous Kafka replication approaches. It can successfully geo-replicate topic data and metadata across clusters, including offsets, consumer groups and authorization command lines (ACLs). MM2 preserves partitioning and detects new topics and partitions. We appreciated the ability to stage a cluster migration over time, an approach that can be useful in migrating from an on-prem cluster to a cloud cluster. After synchronizing the topics and consumer groups, we first migrated the clients to the new cluster location, then we migrated the producers to the new location and finally turned off MM2 and decommissioned the old cluster. We've also seen MM2 used in disaster recovery and high-availability scenarios.
