第 6 章
可靠的数据传递
对于系统来说，可靠的数据传递不能成为马后炮。与性能一样，在系统的设计之初就应该
考虑可靠性问题，而不能在事后才来考虑。而且，可靠性是系统的一个属性，而不是一
个独立的组件，所以在讨论
Kafka
的可靠性保证时，还是要从系统的整体出发。说到可靠
性，那些与
Kafka
集成的系统与
Kafka
本身一样重要。正因为可靠性是系统层面的概念，
所以它不只是某个个体的事情。
Kafka
管理员、
Linux
系统管理员、网络和存储管理员以及
应用程序开发者，所有人必须协同作战，才能构建一个可靠的系统。
Kafka
在数据传递可靠性方面具备很大的灵活性。我们知道，
Kafka
可以被用在很多场景
里，从跟踪用户点击动作到处理信用卡支付操作。有些场景要求很高的可靠性，而有些则
更看重速度和简便性。
Kafka
被设计成高度可配置的，而且它的客户端
API
可以满足不同
程度的可靠性需求。
不过，灵活性有时候也很容易让人掉入陷阱。有时候，你的系统看起来是可靠的，但实
际上有可能不是。本章先讨论各种各样的可靠性及其在
Kafka
场景中的含义。然后介绍
Kafka
的复制功能，以及它是如何提高系统可靠性的。随后探讨如何配置
Kafka
的
broker
和主题来满足不同的使用场景需求，也会涉及生产者和消费者以及如何在各种可靠性场景
里使用它们。最后介绍如何验证系统的可靠性，因为系统的可靠性涉及方方面面——一些
前提条件必须先得到满足。
6.1
可靠性保证
在讨论可靠性时，我们一般会使用
保证
这个词，它是指确保系统在各种不同的环境下能够
发生一致的行为。 ...
