Question

我通过Camel Route将appx 1000条消息/秒发送到ActiveMQ队列。 Camel Context如下：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring"

         http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">


<camelContext id="MsgServlet" xmlns="http://camel.apache.org/schema/spring">

             <to uri="bean:InitConfig?method=process"/>

            </route>


        <route id="servletToProcessor">

              <unmarshal>
                <json library="Jackson"/>
            </unmarshal>

             <to uri="activemq:queue:inbox" pattern="InOnly"/>
            </route>

         <route id="inToOutRoute">

我面临的问题是，它耗费了大量时间来清空队列。我最早要清理队列需要做哪些配置更改？

这可以通过增加并发消费者的数量来实现，即水平或使用线程模型。骆驼文档表明，线程是并发消费者的更快选择。

这是一个很好的讨论话题，描述了这个：Apache Camel concurrentConsumers vs threads
