zookeeper 系列 官方翻译简介(一)

Welcome to Apache ZooKeeper™

Apache ZooKeeper is an effort to develop and maintain anopen-source server which enables highly reliable distributedcoordination.

What is ZooKeeper?

ZooKeeper is a centralized service for maintainingconfiguration information, naming, providing distributedsynchronization, and providing group services. All of these kindsof services are used in some form or another by distributedapplications. Each time they are implemented there is a lot of workthat goes into fixing the bugs and race conditions that areinevitable. Because of the difficulty of implementing these kindsof services, applications initially usually skimp on them ,whichmake them brittle in the presence of change and difficult tomanage. Even when done correctly, different implementations ofthese services lead to management complexity when the applicationsare deployed.

ZooKeeper: Because Coordinating Distributed Systems is aZoo

ZooKeeper is a high-performance coordination service fordistributed applications. It exposes common services - such asnaming, configuration management, synchronization, and groupservices - in a simple interface so you don't have to write themfrom scratch. You can use it off-the-shelf to implement consensus,group management, leader election, and presence protocols. And youcan build on it for your own, specific needs.

The following documents describe concepts and procedures toget you started using ZooKeeper. If you have more questions, pleaseask the mailing list or browse the archives.

阿帕奇zookeeper 是一个致力于开发和管理开源服务器,并且能实现高可靠性的分布式协调框架.

  apache zookeeper是什么

 zookeeper是一个集中式的服务,包括管理配置信息,命名服务,提供分布式的同步,以及提供分组服务等.所有这些类型的服务都在分布式应用中

    以不同形式在使用.  

    每一实现某个服务的时候,都有非常多的工作需要做,比如修复bug,解决竞争冲突不可避免的问题. 

    由于实现这些服务是非常困难的,我们开发应用的一开始都对这些服务不太上心, 当出现变更的时候,他们的系统会变的非常脆弱及难以维护.

   甚至当有些时候做的是正确,这些服务的不同实现会导致应用部署的时候,管理会非常的复杂.

Zookeeper: 因为管理协调分布式系统就是一个动物园

    zookeeper是一个高性能的分布式应用协调服务框架. 它以一种简单接口的形式暴露了一系列的通用服务,比如命名,配置管理,同步,分组等,

   因此你不必从一堆草稿中去实现他们.你可以使用现成的东西去实现一直性,分组管理,选择,已经表现协议.同时你能够用它构建实现自己特定的需求.

   接下来的文档描述了一些概念和过程,让你开始使用zookeeper,如果你有其他问题,可以咨询邮件列表或者直接找对应的说明文档.
