在上一篇文章中( JStorm 源码分析 - tuple 在整个拓扑中的流转过程), 我们多次提到 JStorm 使用了 3 个队列来完成 tuple 的缓冲与消费. 因此这些队列的性能会制约 JStorm 的总体的吞吐量. 在日常的工程实践当中, 我们会使用一些 Java 的内置队列来完成这个工作, 比如 ArrayBlockingQueue. 实际上, 如果要追求更高的性能, Disrupt

byte[]数组作为key值,只是数组的地址的引用的hashcode,不能够根据byte[]数组的内容来,创建相应的hashcode,也就是所谓的索引key。所以,如果想用byte[]数组来作为map的key值的话,有三种方法: 将byte[],先转化为string 将采用list 将byte[]自己包装,使用byte[]数组的内容来重写hashcode和equals方法
