+
+== Protocol Buffers 简介
+如果你在互联网上搜索的话，你可能会看到下面的说明文字。
+
+""
+Google Protocol Buffer( 简称 Protobuf) 是 Google 公司内部的混合语言数据标准，目前已经正在使用的有超过 48,162 种报文格式定义和超过 12,183 个 .proto 文件。
+
+他们用于 RPC 系统和持续数据存储系统。
+
+Protocol Buffers 是一种轻便高效的结构化数据存储格式，可以用于结构化数据串行化，或者说序列化。
+
+它很适合做数据存储或 RPC 数据交换格式。可用于通讯协议、数据存储等领域的语言无关、平台无关、可扩展的序列化结构数据格式。
+
+目前提供了 C++、Java、Python 三种语言的 API。
+""
+
+我们是在实际的数据处理的时候，需要使用 JSON 来序列化数据，但是又考虑到 JSON 在传输的时候数据过大，同时还有很多并不需要的垃圾文件。
+我们才考虑到了 Protocol Buffer 提供的功能。
