Hi,
ZooKeeper works as high-performance co-ordinatior services in distributed Kafka cluster. You can't run Kafka(cluster) without it.
Kafka connects to Zookeper and if ZooKeeper is down Kafka won't run.
ZooKeeper is used as communication middleware to communicate between different nodes in Kafka cluster.
ZooKeeper is used to commit offset in the Kafka cluster and if node fails it retrieves the data from perviously committed offset.
ZooKeeper is also responsible with the functionalities like leader detection, distributed synchornization, configuration management etc..
It also handles cluster activities like leaves or joins by nodes, node status in real-time, hearbeat management etc..
It is also used to track the status of each node present in the Kafka cluster and keep track of topics, messagess, status etc..
