NOT ON THE CURRENT EDITION
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.

Trial
基于 Kafka Connect 框架构建的MirrorMaker 2.0 (也称为 MM2 )，弥补了以前 Kafka 复制工具中的许多短板。它可以成功地跨集群 geo-replicate 主题数据和元数据，包括偏移量、消费者组和授权命令行( authorization command lines, ACLs )。MM2 能够保留分区，并能检测新的主题和分区。我们很欣赏其所具备的下述逐步进行集群迁移的能力（当从本地集群迁移到云集群时，这种方法尤其有用）：同步主题和消费者组之后，先把客户端迁移到新集群里；然后把生产者迁移到新集群里；最后关闭 MM2，并将旧集群下线。此外，MM2 还可用于灾难恢复和高可用性场景。
