What is geo-replication in Kafka?

1.	What is geo-replication in Kafka?
Answer» The geo-replication enables replication across different data or different clusters. The Kafka mirror maker enables geo-replication. This process is called mirroring. The mirroring process is different from replication across different nodes in the same CLUSTER. Kafka’s mirror maker ensure messages from topic belonging to one or more Kafka clusters are replicated to DESTINATION cluster with same topic names. We should USE at least one mirror maker to replicate one source cluster. We can have multiple mirror maker processes to mirror topics within the same consumer groups. This enables HIGH throughput and enable the system. If one of the mirror maker processes goes down, the other can take over the additional load. One thing is very important here as the source and destination clusters are independent of each other having different PARTITION and offsets.
