hyperf-reset-transaction's Introduction

组件简介

基于Hyperf框架的重置型分布式事务组件，适用于服务化之后调用http协议的api接口

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。
遵守两段提交协议，属于强一致性事务，高并发下，支持读已提交的事务隔离级别。
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。

解决了哪些并发场景

一个待发货订单，用户同时操作发货和取消订单，只有一个成功
积分换取优惠券，只要出现积分不够扣减或者优惠券的库存不够扣减，就会全部失败。
