Mule VM Queue线程配置

Question

我试图了解如何使用 3.5 CE 微调 Mule 中的线程配置文件

流量1

从 FTP 端点获取文件并将其池化为 VM 队列。

流程2

从启用事务的上述 VM 队列中读取并进行一些业务逻辑处理。

---

我假设 Flow 2 将根据 VM 连接器线程配置在多个线程中执行。但我注意到的是，第二个流程总是使用 4 个线程来并行执行它。已尝试配置默认线程配置文件，它也没有任何区别。请让我知道我缺少什么。任何帮助表示赞赏

示例 VM 连接器配置

  <vm:connector name="ITS_VM" validateConnections="true"   >
    <receiver-threading-profile  maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40"/>
    <dispatcher-threading-profile maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40"/>
     <vm:queue-profile  maxOutstandingMessages="500">
         </vm:queue-profile>
    </vm:connector>

示例默认配置

<configuration >
    <default-threading-profile  maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40" />
    <default-dispatcher-threading-profile maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40"/>
    <default-receiver-threading-profile maxThreadsIdle="30" maxBufferSize="5000" maxThreadsActive="40" />
        </configuration>

Answer 1

从 Mule jars 调试源代码后，我发现我还需要设置轮询 VM 队列的消费者数量。

我通过将 vm:connector 上的 numberOfConcurrentTransactedReceivers 设置为更高的数字来实现此目的。默认值为 4，这就是为什么我只看到 4 个并行线程。

它现在工作正常。希望这对某人有用

<vm:connector name="ITS_VM" validateConnections="true" createMultipleTransactedReceivers="true" numberOfConcurrentTransactedReceivers="30" >
