-# 跨语言分布式事务管理器
+# [中文文档](http://dtm.pub)
-DTM是一款变革性的分布式事务框架，提供了傻瓜式的使用方式，极大的降低了分布式事务的使用门槛，改变了“能不用分布式事务就不用”的行业现状。 dtm 的应用范围非常广，可以应用于以下常见的领域：
-- [非单体的订单系统，大幅简化架构](https://dtm.pub/app/order.html)
-- [秒杀系统，做到在Redis中精准扣库存](https://dtm.pub/app/flash.html)
-- [保证缓存与DB的一致性](https://dtm.pub/app/cache.html)
-- 微服务架构(已原生支持[go-zero](https://github.com/zeromicro/go-zero)等框架)中跨服务更新数据保证一致性

+## What is DTM
-## 与其他框架对比
+DTM is the first distributed transaction management framework in Golang. Unlike other frameworks, DTM provides extremely easy access interfaces of HTTP and gRPC, supports multiple language bindings, and handles tricky problems of unordered sub-transactions at the framework level.
-非Java语言类的，暂未看到除dtm之外的成熟框架，因此这里将DTM和Java中最成熟的Seata对比：

+## DTM vs. others
-## 快速开始
+There is no mature open-source distributed transaction framework for non-Java languages.
+Mature open-source distributed transaction frameworks for Java language include Ali's Seata, Huawei's ServiceComb-Pack, Jingdong's shardingsphere, himly, tcc-transaction, ByteTCC, and so on, of which Seata is most widely used.
-如果您不是Go语言，可以跳转[各语言客户端及示例](https://dtm.pub/ref/sdk.html#go)，里面有相关的快速开始示例
+The following is a comparison of the main features of dtm and Seata.
-### 运行dtm
+
+| Features | DTM | Seata | Remarks |
+| :-----: | :----: | :----: | :----: |
+| Supported languages | Golang, Python, PHP, and others | Java | dtm allows easy access from a new language |
+| Exception handling | [Sub-transaction barrier](https://zhuanlan.zhihu.com/p/388444465) | manual | dtm solves idempotent transaction, hanging, null compensation |
+| TCC | ✓ | ✓ | |
+| XA | ✓ | ✓ | |
+| AT | suggest XA | ✓ | AT is similar to XA with better performance but with dirty rollback |
+| SAGA | support concurrency | complicated state-machine mode | dtm's state-machine mode is being planned |
+| Transactional Messaging | ✓ | ✗ | dtm provides Transactional Messaging similar to RocketMQ |
+| Multiple DBs in a service |✓|✗||
+| Communication protocols | HTTP, gRPC | Dubbo, no HTTP | |
+| Star count | | | dtm 0.1 is released from 20210604 and under fast development |
+
+From the features' comparison above, if your language stack includes languages other than Java, then dtm is the one for you.
+If your language stack is Java, you can also choose to access dtm and use sub-transaction barrier technology to simplify your business development.
+
+## [Cook Book](https://en.dtm.pub)
+
+# Quick start
+
+### run dtm
``` bash
git clone https://github.com/dtm-labs/dtm && cd dtm
go run main.go
```
-### 启动并运行一个saga示例
-下面运行一个类似跨行转账的示例，包括两个事务分支：资金转出（TransOut)、资金转入（TransIn)。DTM保证TransIn和TransOut要么全部成功，要么全部回滚，保证最终金额的正确性。
+### Start the example
``` bash
git clone https://github.com/dtm-labs/dtmcli-go-sample && cd dtmcli-go-sample
go run main.go
```
-## 接入详解
+# Code
-### 接入代码
-``` GO
- // 具体业务微服务地址
+### Use
+``` go
+ // business micro-service address
const qsBusi = "http://localhost:8081/api/busi_saga"
- req := &gin.H{"amount": 30} // 微服务的载荷
- // DtmServer为DTM服务的地址，是一个url
+ // The address where DtmServer serves DTM, which is a url
DtmServer := "http://localhost:36789/api/dtmsvr"
- saga := dtmcli.NewSaga(DtmServer, dtmcli.MustGenGid(DtmServer)).
- // 添加一个TransOut的子事务，正向操作为url: qsBusi+"/TransOut"， 补偿操作为url: qsBusi+"/TransOutCom"
- Add(qsBusi+"/TransOut", qsBusi+"/TransOutCom", req).
- // 添加一个TransIn的子事务，正向操作为url: qsBusi+"/TransIn"， 补偿操作为url: qsBusi+"/TransInCom"
- Add(qsBusi+"/TransIn", qsBusi+"/TransInCom", req)
- // 提交saga事务，dtm会完成所有的子事务/回滚所有的子事务
- err := saga.Submit()
+ req := &gin.H{"amount": 30} // micro-service payload
+ // DtmServer is the address of DTM micro-service
+ saga := dtmcli.NewSaga(DtmServer, dtmcli.MustGenGid(DtmServer)).
+ // add a TransOut subtraction，forward operation with url: qsBusi+"/TransOut", reverse compensation operation with url: qsBusi+"/TransOutCom"
+ Add(qsBusi+"/TransOut", qsBusi+"/TransOutCom", req).
+ // add a TransIn subtraction, forward operation with url: qsBusi+"/TransIn", reverse compensation operation with url: qsBusi+"/TransInCom"
+ Add(qsBusi+"/TransIn", qsBusi+"/TransInCom", req)
+ // submit the created saga transaction，dtm ensures all subtractions either complete or get revoked
+ err := saga.Submit()
```
+### Complete example
-成功运行后，可以看到TransOut、TransIn依次被调用，完成了整个分布式事务
+Refer to [dtm-examples](https://github.com/dtm-labs/dtm-examples).
-### 时序图
+### Slack
-上述saga分布式事务的时序图如下：
+You can join the [DTM slack channel here](https://join.slack.com/t/dtm-w6k9662/shared_invite/zt-vkrph4k1-eFqEFnMkbmlXqfUo5GWHWw).
-
+### Wechat
-### 失败情况
-在实际的业务中，子事务可能出现失败，例如转入的子账号被冻结导致转账失败。我们对业务代码进行修改，让TransIn的正向操作失败，然后看看结果
-
-``` go
- app.POST(qsBusiAPI+"/TransIn", func(c *gin.Context) {
- logger.Infof("TransIn")
- c.JSON(409, "") // Status 409 表示失败，不再重试，直接回滚
- })
-```
-
-再运行这个例子，整个事务最终失败，时序图如下：
-
-
-
-在转入操作失败的情况下，TransIn和TransOut的补偿操作被执行，保证了最终的余额和转账前是一样的。
