Kafka disaster recovery on Kubernetes with CSI
Apache Kafka was designed with a heavy emphasis on fault-tolerance and high-availability in mind, and thus provides different methods of ensuring enterprise-grade resiliency such as:
replication factor - which defines how many partition replicas of a topic should be kept, each one being stored on a different broker. A replication factor of N allows for the loss of N-1 brokers. The new brokers will replace the lost brokers until the number of remaining broker(s) reaches the replication factor, or the number of copies of the partitions of a topic.
