alibaba-mom

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
