The service has a short name of zoo1 which. ZooKeeper: A ZooKeeper is used to store information about the Kafka cluster and details of the consumer clients. It manages brokers by maintaining a list of them. Also, a ZooKeeper is responsible for choosing a leader for the partitions. If any changes like a broker die, new topics, etc., occurs, the ZooKeeper sends notifications to Apache Kafka Kafka makes use of a tool called ZooKeeper which is a centralized service for a distributed environment like Kafka. It offers configuration service, synchronization service, and a naming registry for large distributed systems. You can read more about it here.
