> Our organization (walmart.com) has been a Kafka user since some years back and MirrorMaker has been a convenient tool to bring our Kafka data from one Kafka cluster to another cluster.
> In many our use cases, the mirrored topic from the source cluster may not want to have the same name in the target cluster. This could be a valid scenario when the same topic name already exists on the target cluster, or we want to append the name of the data center to the topic name in the target cluster, such as "grocery_items_mirror_sunnyvale", to explicitly identify the source (e.g. sunnyvale) and nature (e.g. mirroring) of the topic.
> We have implemented the MirrorMaker topic renaming feature internally which has been used for production over a couple of years. While keeping our internal Kafka fork with the above "renaming" branch across version upgrade does not cost us too much labor, we think it may be meaningful to contribute back to the community so that potentially many people may have the similar expectation and could benefit from this feature.
