I have currently setup a cluster. I've used Apache Kafka and zookeeper. But still, I still don't get its usage in the cluster. When are both required and for what requirement?

Apache Kafka is a tool used in Streaming Real-time data.

Kafka consists of:

  • Producer
  • Consumer

  • Zookeeper
Producer generates the topic.
Consumer subscribes to the topic.
The topics published are stored in Kafka Clusters or Brokers.
