2015 ali中间件比赛项目,1. 通信模块: 涉及到了消息架构设计,每一个主题分配1-2个队列,这个是可以横向增加,考虑到了一个主题有多个消费者订阅,而且还有过滤条件,为了负载均衡,对应的队列投递消息是根据随机数对队列数取膜完成的。以上是内存队列。 2. 持久化系统:因为考虑到机器坏掉,broker不可用等等原因导致的消息丢失,就需要每次收到的消息必须及时落盘,这个就是比赛优化的重中之重。为此设计了一个小型的文件系统,借鉴阿里的rocketmq. 用一个大的日志文件,一般1G大小每个,和内存队列的结构映射到实体队列。整个日志文件是顺序文件,每条消息固定大小,里面有对应的队列号,消息号,还有长度等等。这个方便恢复消息到实体队列用的。 同步刷盘,异步刷盘,持久化必须可靠,所以一般是同步刷盘到日志文件,日志文件定时异步刷盘到实体队列,实体队列里面是索引,消息的本体在日志文件里面。为了加快大面积的写入速度,用了内存映射:内存映射文件首先将外存上的文件映射到内存中的一块连续区域,被当成一个字节数组进行处理,读写操作直接对内存进行操作,而后再将内存区域重新映射到外存文件,这就节省了中间频繁的对外存进行读写的时间,大大降低了读写时间
