评估当前的流市场

在我写这本书的时候，旨在取代
HTTP/2
的互联网协议的
HTTP/3
正处于开发
阶段。它利用了一种
TCP
协议的潜在替代品
QUIC
（奇怪的是，
QUIC
并不
代表任何东西）来同时在多个连接上传递流。这将显著提高
HTTP
流的性能，
特别是当在一个连接上出现网络问题并开始丢失数据包时。
Internet
工程任务组目前正在编写
HTTP/3
规范，但已经有很多浏览器和
Web
服务器宣布支持该规范的早期版本。

事件处理
最后介绍的这个架构是一个专门引入工具来处理事件流流量的架构。消息传
递系统和网络协议负责将事件分发到相应的处理地方，但它们最初并不打算
成为一个发生其他形式交互的地方。
正如在第
1
章中所提到的，没有交互作用的流就只是单纯的移动数据。那些
只负责准备提交到流的事件的应用程序，或仅使用流中的事件的应用程序之
间的交互，对于流来说无疑是至关重要的，但这两种应用程序都不支持流的
延续，不能在整个应用程序系统中增强这些事件的影响。
