The ‘Zoo’ node is reference to the Zookeeper cluster that we were using to orchestrate resiliency between the Kafka instances. One of the tools out there to support this mechanism is Apache Kafka. A 7 node would be much more stable. It allows the Kafka brokers to subscribe to itself and know whenever any change regarding a partition leader and node distribution has happened. Repeat this procedure on all the nodes of the Kafka cluster. For a small enterprise cluster, you’d be looking at 3-5 nodes depending on how much node failure you want to survive. id=2" on computer 192. The Zookeeper ensemble will tell Kafka that there are other Kafka nodes connected to it, sending them the message that it is part of a Kafka cluster. Some of the basic operations you'll need to do after you have started DSE on your first node is eventually add more nodes to scale out your cluster, replace nodes if a node one day fails (let's face it, hardware eventually fails), or possibly look at decommissioning and removing nodes to reduce the size of your cluster or move nodes to another location (Datacenter or cluster).
