+### 一个朴素的想法
+作为一个刚入 Golang 坑的微服务普通开发者来讲，很容易产生一个朴素的想法，希望 Golang 微服务也有分布式事务解决方案。我们注意到阿里开源了 Java 版的分布式事务解决方案 Seata，本项目尝试将 Java 版的 Seata 改写一个 Golang 的版本。
+在 Seata 没有 Golang 版本 client sdk 的情况下，Golang 版本的 TC Server 使用了和 Java 版 Seata 一样的通信协议，方便调试。
+目前，基于内存的 TC Server 已实现。希望有同样朴素想法的开发者加入我们一起完善 Golang 版本的分布式事务解决方案。

+ * 参考 [effective go 之 Embedding](#https://my.oschina.net/pengfeix/blog/109967)
+ * Go does not provide the typical, type-driven notion of subclassing,
+ * but it does have the ability to “borrow” pieces of an implementation
+ * by embedding types within a struct or interface.
+ * Go 没有像其它面向对象语言中的类继承概念，但是，它可以通过在结构体或者接口中嵌入
+ * 其它的类型，来使用被嵌入类型的功能。
+ *
+ * 原本 JAVA 版 Seata Sever 设计了 Core 接口，AbstractCore 实现该接口，ATCore、
+ * TccCore、SagaCore 都继承 AbstractCore。使 ATCore、TccCore、SagaCore 每一
+ * 个类单独拿出来都是 Core 接口的实现。但 Go 版的 Seata 我不打算这样设计。我们将
+ * Core 接口里定义的接口方法拿出来，如上面的表格所示，一个全局事务的周期分别对应 Begin、
+ * BranchRegister、BranchReport、Commit、Rollback 接口方法，这些接口方法适用于
+ * AT 模式和 TCC 模式（SAGA 模式暂不了解，先不考虑）。AT 模式会多一个 LockQuery
+ * 的接口。另外 OutBound 方向上有两个接口 branchCommit、branchRollback。JAVA 版
+ * 的设计中 doGlobalCommit、doGlobalRollBack、doGlobalReport 其实是私有方法,
+ * 这里用首字母小些开头的方法区分。那么 Go 版本的 DefaultCore 设计就出来了（暂不考虑 SAGA），
+ * DefaultCore 内嵌入 ATCore。
