分布式可靠消息组件
@knightliao,感谢提供pikaQ组件来实现分布式可靠消息(虽然还没有release)。我的问题是,是否考虑过IMDG的一些技术来达到这个手段(下述是我的一些理解,不足之处请斧正)
我的想法(不知是否可行):
上面的考虑是考虑引入针对hazelcast等transactionManager支持(看可否不考虑AOP方式)
根据您“基于RMQ的可靠消息系统设计(设计图)”中理解,应该是“pikaQ”会回调业务系统的接口“判断是否业务处理服务”成功,这里面有两个问题:
1、这个接口的判断一般是在消息发送之前(入MQ队列)前发送,还是在消息发送后由消息消费者使用?
2、由于该接口是业务相关的,在“pikaQ”中是否有做封装?我并未从测试用例中找到判断“业务处理服务成功”的逻辑,能否帮忙提供下具体程序位置吗?
另外,我理解按照pikaQ设计,所有的消息都应该存储在一个数据库中,那未来业务量很大的时候,数据库是否会存在瓶颈?
非常感谢!
我看了一下实现代码,消息的持久化要和业务事物域用同一个数据库事物? 是否可以持久化和rabbitmq抽取出来,这样消息数据独立存储、独立伸缩、降低业务系统与消息系统间的耦合
