<p style="text-align: center;"><img alt="" src="https://simg.open-open.com/show/03379414b3572debc448e04f087c61aa.jpg" /></p> <p>RabbitMQ是实现AMQP（高级消息队列协议）的消息中间件的一种，最初起源于金融系统，用于在分布式系统中存储转发消息，在易用性、扩展性、高可用性等方面表现不俗。消息中间件主要用于组件之间的解耦，消息的发送者无需知道消息使用者的存在，反之亦然。</p> <p>AMQP 里主要要说两个组件：Exchange 和 Queue （在 AMQP 1.0 里还会有变动），如下图所示，绿色的 X 就是 Exchange ，红色的是 Queue ，这两者都在 Server 端，又称作 Broker ，这部分是 RabbitMQ 实现的，而蓝色的则是客户端，通常有 Producer 和 Consumer 两种类型。</p> <p style="text-align: center;"><img alt="" src="https://simg.open-open.com/show/19415a1a9b5dc387fd8324f77163bd3a.jpg" /></p> <h2>更新日志</h2> <h3>Server</h3> <p>Bug修复</p> <ul> <li> <p>Nodes on Windows will successfully start if Erlang is installed in a directory with spaces<br /> in the path.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992224538678258">rabbitmq-server#859</a></p> </li> <li> <p>Node health check is now node-local, is it was meant to be.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992224641906835">rabbitmq-server#818</a></p> </li> <li> <p>Queue deletion and termination will no longer leave "tomb stone" messages in message store<br /> files. This eliminates the confusing behavior when a node or cluster having no messages<br /> enqueued could have many thousands of such "marker" messages in the message store.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992224733917172">rabbitmq-server#839</a></p> </li> </ul> <p>功能增强</p> <ul> <li> <p>Erlang VM scheduler binding type default has changed to <code>db</code>. This means fewer<br /> CPU context switches for some workloads.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992224828583700">rabbitmq-server#612</a></p> </li> </ul> <h3>Management Plugin</h3> <p>Bug修复</p> <ul> <li> <p>HTTP API is now compatible with Erlang 19.0.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992224923640565">rabbitmq-management#244</a></p> </li> <li> <p>Temporary tables are no longer named using atoms, preventing a potential<br /> exhaustion of the runtime atom table.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992225009479473">rabbitmq-management#245</a></p> </li> <li> <p>Cluster links and traffic charts are correctly displayed again</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992500732530941">rabbitmq-management#250</a></p> </li> <li> <p>Runtime metric charts now have a description pop-up associated with them.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992225102580242">rabbitmq-management#247</a></p> </li> </ul> <h3>AMQP 1.0 plugin</h3> <p>Bug修复</p> <ul> <li> <p>When an AMQP 1.0 specified its own list of source outcomes in a link<br /> attachment, it caused a crash of its session on the server. Now a<br /> protocol error is raised if the list contains invalid outcomes.</p> <p>GitHub issue: <a href="/misc/goto?guid=4958992500863994661">rabbitmq-amqp1.0#31</a></p> </li> </ul> <h3>Java
