云消息队列 MQ线程的相关内容

rocketMQ 5.X消费者消费完成后，链接线程没有关闭，导致达到连接数上限。

各位大佬，在使用rocketMQ 5.X时候，消费者在消费完成之后，链接没有关闭，会一直存活，在消费4000个消息后，连接池就满了，请问事哪里设置的不对吗，还是消费者这边代码有问题呢，感谢各位大佬

在RocketMQ中解锁之前共享变量(单例的引用)不是不会刷新到主存被其他线程看到吗？

有个问题先要探讨下：在RocketMQ中都说DoubleCheck(无volatile版本)检查会出现空指针异常，原因是对象实例化顺序被打乱，导致未初始化的对象引用被其他线程引用后第一层判空直接通过后执行了单例相关对象的属性导致空指针，但是根据JMM规范的约定，在Synchronize解锁之前共享变...

【Alibaba中间件技术系列】「RocketMQ技术专题」带你一起去探索RocketMQ服务架构的线程模型分析

前言介绍RocketMQ 是个消息服务器，也是个网络服务器。接下来我们将从网络 IO 模型，线程模型，看看 RocketMQ 是如何设计的。IO 模型RocketMQ 使用了 Netty 作为网络通信框架，自然而然使用了 Reactor 模型，或者说 Select 模型、Epoll 模型。即一个线程...

开箱即用！动态修改RocketMQ线程池

前言上一篇文章中提到了动态修改RocketMQ线程池，那我们如何才能够通过管理页面对不同消费者组的线程池进行管理自由的随着业务波动进行平滑修改，降低线程池参数修改的成本。另外，从功能性以及健壮性而言还有许多值得我们思考的地方，科宇通过查看线程池运行时指标、负载报警、配置日志管理来提高我们对线程池的管...
