> Implement partial mirroring functionality in Kafka Mirror Maker

> Key: KAFKA-3609
> URL: https://issues.apache.org/jira/browse/KAFKA-3609
> Project: Kafka
> Issue Type: New Feature
> Components: core
> Affects Versions: 0.9.0.0
> Reporter: Sukhdev Saini
>
> It will be useful to implement partial or subset of partitions mirroring
> functionality in Kafka Mirror Maker.
> This will be useful in number of scenarios:
> 1. Where business hosts two separate AWS clusters and mirroring everything
> might be quite expensive.
> 2. Mirror cluster is maintaining some kind of local state associated with
> subset of partitions (like a local on-disk key-value store) and hence it
> should only mirror partitions it is maintaining on disk.
