---------------------------------
Summary: MirrorMaker topic renaming
Key: KAFKA-3841
URL: https://issues.apache.org/jira/browse/KAFKA-3841
Project: Kafka
Issue Type: New Feature
Components: tools
Affects Versions: 0.10.0.0
Reporter: Ning Zhang
Our organization (walmart.com) has been a Kafka user since 3 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 2 years. Keeping our internal Kafka fork with the
above "renaming" branch across version upgrade does not cost us too much labor,
but 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.
