> Key: KAFKA-13691
> URL: https://issues.apache.org/jira/browse/KAFKA-13691
> Project: Kafka
> Issue Type: Improvement
> Components: config, mirrormaker
> Affects Versions: 2.4.1, 2.7.2
> Reporter: Eugeniu Cararus
> Priority: Minor
> Labels: need-kip, pull-request-available
> Original Estimate: 1h
> Remaining Estimate: 1h

> When I use mirrormaker it replicates the topics with different name, name of
> target is built based on
> {code:java}
> sourceClusterAlias + separator + topic {code}
>
> implementation is
> [here|https://github.com/apache/kafka/blob/trunk/connect/mirror-client/src/main/java/org/apache/kafka/connect/mirror/DefaultReplicationPolicy.java#L49].
> Proposed improvement consist in:
> Adding new config property key: target.replication.policy.topic_map
> E.I.
> {code:java}
> source-> target.replication.policy.class=
> org.apache.kafka.connect.mirror.RenameTopicReplicationPolicy
> source->target.replication.policy.separator = .
> source->target.replication.policy.topic_map=
> SOURCER_TOPIC_A,DESTINATION_TOPIC_A; SOURCER_TOPIC_B,DESTINATION_TOPIC_B;
> {code}
> and add new RenameTopicReplicationPolicy which will be responsible to:
> 1. override configure method load target.replication.policy.topic_map into a
> Map where Key is source topic name and value is target topic name
>
> 2. override formatRemoteTopic so the target topic name will be loaded based
> on config
> {code:java}
> @Override
> public String formatRemoteTopic(String sourceClusterAlias, String topic) {
> String targetTopic = topicMap.containsKey(topic) ? topicMap.get(topic) :
> topic ;
> return super.formatRemoteTopic(sourceClusterAlias,targetTopic);
> } {code}
