组件简介

基于分布式事务RT模式实现，适用于hyperf框架的组件。

如何使用

在hyperf框架里，把门面Db换成RT就能实现分布式事务。

use Hyperf\DbConnection\Db;
use Windawake\HyperfResetTransaction\Facades\RT;

Db::beginTransaction();
...
Db::commit();

#换成
RT::beginTransaction();
...
RT::commit();

快速预览

第一步，在hyperf框架根目录下安装composer组件

## 必须使用composer2版本
composer require windawake/hyperf-reset-transaction dev-master

第二步，在./config/autoload/server.php文件，默认使用9501端口配置，然后增加9502，9503端口的配置

    'servers' => [
        [
            'name' => 'http',
            'type' => Server::SERVER_HTTP,
            'host' => '0.0.0.0',
            'port' => 9501,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
            ],
        ],
        [
            'name' => 'http',
            'type' => Server::SERVER_HTTP,
            'host' => '0.0.0.0',
            'port' => 9502,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
            ],
        ],
        [
            'name' => 'http',
            'type' => Server::SERVER_HTTP,
            'host' => '0.0.0.0',
            'port' => 9503,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
            ],
        ]
    ],

第三步，删除runtime文件夹，然后创建order，storage，account3个mysql数据库实例，3个控制器，3个model，在phpunit.xml增加testsuite Transaction，然后启动web服务器。这些操作只需要执行下面命令全部完成

rm -rf ./runtime && php ./bin/hyperf.php resetTransact:create-examples && php ./bin/hyperf.php start

最后一步，运行测试脚本 composer test -- --testsuite=Transaction --filter=ServiceTest运行结果如下所示，3个例子测试通过。

DESKTOP:/web/linux/php/hyperf/hyperf22# composer test -- --testsuite=Transaction --filter=ServiceTest
Time: 00:00.596, Memory: 18.00 MB

OK (3 tests, 12 assertions)

功能特性

开箱即用，不需要重构原有项目的代码，与mysql事务写法一致，简单易用。
两段提交的强一致性事务，高并发下，支持读已提交的事务隔离级别，数据一致性100%接近mysql xa。
性能超过seata AT模式，由于事务拆分成多个，变成了几个小事务，压测发现比mysql普通事务更少发生死锁。
支持分布式事务嵌套，与savepoint一致效果。
支持避免不同业务代码并发造成脏数据的问题。
默认支持http协议的服务化接口，想要支持其它协议则需要重写中间件。
支持子服务嵌套分布式事务（全球首创）。
支持服务，本地事务和分布式事务混合嵌套（全球首创）
支持超时3次重试，重复请求保证幂等性
支持go，java语言（开发中）

测试报告

本地电脑：i5-9400F 24G内存 wsl ubuntu

压测场景：

1）创建一个简单的订单 1000请求 100并发

2）订单服务创建一个订单，然后库存服务扣减库存，最后账户服务扣减金额 1000请求 100并发

报告总结：

1）使用RT模式，创建一个订单的消耗性能跟普通事务创建一个订单+7条简单sql语句差不多

2）一个完整的创建订单是包含订单服务，库存服务和账户服务。使用RT模式，qps从109下降到53，性能大约是不使用分布式事务的1/2

压测前准备：

做测试之前需要设置mysql最大连接数为3000：

set global max_connections=3000;

压测创建一个订单 + 7条简单订单查询

加7条简单的sql语句，是因为RT分布式事务，后面处理的逻辑大约有7条sql，这样方便比较。
