First, distributed coordination technology Before we introduce zookeeper to you, we introduce a technology-distributed coordination technology. So what is distributed coordination technology. So let me tell you, in fact, distributed coordination technology is mainly used to solve the distributed environment among the multiple processes of synchronization control, so that they have an orderly access to a critical resource, to prevent the consequences

Zookeeper is an open source distributed Coordination Service , created by Yahoo, and is an open-source implementation of Google Chubby . Distributed applications can implement functions such as data Publishing/subscriptions, load balancing, naming services, distributed coordination/notification, cluster Management, master elections, distributed locks, and distributed queues based on
