title: **Kafka** Bi-directional sync between datacenter across regions
body: <p>I have a deployment where we are using kafka to send messages from the services. But we need to have master Kafka in all the regions. So once the message is pushed in 1 data center, it should be synced in other. And when it is done in other data center again it should be synced back. Mirror Maker can offer sync from 1 to other, but how do I achieve the bi-directional sync?</p>
