面试题：一个consumer订阅两个topic，其中一个topic消息过多堆积了，会影响另一个topic消费吗
问题：一个consumer订阅两个topic，其中一个topic消息过多堆积了，会影响另一个topic消费吗
答案：不影响。
为什么呢？
因为rocketmq首先对消息进行负载均衡（rebalance），就是将topic中的队列按照consumer进行分配之后，将pullRequest(里面存放了topic,brokerName,queueId)放入到一个linkedBlockingQueue中，这个时候已经排好了后面消费的顺序。例如100个request中有大概50个是TopicTest1,另外50个是TopicTest2。
在实际进行拉取的时候，多个线程从LinkedBlockingQueue中去take消息，按照放入的顺序进行消费，这个时候topicTest1消息已经堆积了，但还是会照常去消费TopicTest2，如果处理速度不影响的话，只有当TopicTest消费的速度过慢，导致将所有的线程都占住了，那也只是一时的，会影响TopicTest2的消费速度，但不会阻塞TopicTest2的消费。
如下图所示，PullMessageService线程负责将request放入队列，同时NettyClientPublicExecutor_1,2,3,4负责处理消息拉取，他们会并发从队列中获取消息，当获取到消息并处理完后会接着去take新的消息然后继续处理。
