Is the replication factor system in Kafka 0.8 suitable for creating single clusters which span across data centers ? (up to 3)
I am looking for a system where I don't loose messages, and can effectively 'fail over' to a different datacenter for processing if/when the primary goes down. If I read correctly, any message delivered to a Kafka broker, will be copied to its Replica/s. And a producer could deliver messages to any broker in the same replica set.
Is that correct ?
I am aware there are several zookeeper issues around multi DC support which I need to sort out, so this question is specific for the Kafka portion.
Note: My main consumer from Kafka will be STORM.
