etcd vs zookeeper

By this definition we know that zookeeper is a coordinated system, and the object of the action is distributed systems. Why do distributed systems need a coordinated system? The reasons are as follows:It is difficult to develop distributed system, which is mainly embodied in the "partial failure" of distributed system. "Partial failure" means that information is transmitted between two nodes of the network, if the network fails, the sender cannot know

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

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 (

I first recognized zookeeper and made some records. Zookeeper provides a centralized service, including configuration maintenance, service naming, distributed synchronization, and group management. Sub-services are commonly used in distributed applications. Zookeeper Architecture Zookeeper is an open-source Distribute

Name Origin Zookeeper: the Administrator of the Chinese translation zoo. It is a service framework used to coordinate distributed programs. The reason why zookeeper is called is that the author regards these distributed system coordination tasks as a zoo administrator.
