What is 1.ZooKeeper?Zookeeper is a distributed, open source distributed Application Coordination Service, is Google's chubby an open source implementation, it is the manager of the cluster, monitoring the status of each node in the cluster according to the feedback submitted by the node for the next reasonable operation. Finally, the user is provided with an easy-to-use interface and a performance-efficient

Zookeeper ConceptZookeeper is a distributed, open-source distributed Application Coordination Service that contains a simple set of primitives that can be used by distributed applications to implement synchronization services, configure maintenance and naming services, and so on. Zookeeper is a sub-project of Hadoop, and its evolution is not to be mentioned. In distributed applications, a reliable, extensib

This is a creation in Article, where the information may have evolved or changed. "Editor's note" The ETCD team recently released a beta version of ZETCD, a proxy tool that allows ETCD to be compatible with zookeeper protocols, allowing users to disassociate existing applications from the Zookeeper service. Distributed systems usually rely on an arbitration system to work together, and generally such a sys

In a distributed environment, most services allow partial failures and data inconsistency. However, some of the most basic services require high reliability and consistency, these services are the basis for other distributed services, such as naming service and distributed lock. These distributed basic services have the following requirements: High Availability High Consistency High Performance Designing a service that challenges the CAP principle is a challenge and a good research topic. A

There are currently three popular solutions for implementing distributed locks, which are based on databases, redis, and zookeeper. The first two solutions have a lot of information for your reference on the network. Let's take a look at how to implement distributed locks using zookeeper. What is zookeeper? Zookeeper (
