骆驼并行处理选项 [英] Camel parallel processing options

问题描述

我正在使用具有骆驼2.10的RedHat Fuse Service Works中的骆驼路线.

I am working on Camel routes in RedHat Fuse Service Works which has Camel 2.10.

我想知道以下实现之间的区别:

I would like to know the differences between the following implementations:

1/使用SEDA路线

1/ using SEDA routes

    from("A")
    .split(body())
    .to("seda:B");

    from("seda:B?concurrentConsumers=4")
    .routeId("MySEDATestRoute")
    .to("C")
    .end();

2/使用并行处理

   from("A")
    .split(body())
    .parallelProcessing()
    .to("C");

3/使用线程

    from("A")
    .split(body())
    .threads()
    .to("C");

根据我所看到的，方法3(线程)允许配置线程池大小，这似乎与解决方案1(SEDA)的"concurrentConsumers"相同.

From what I've seen the method 3 (threads) allows to configure the thread pool size which seems the same as "concurrentConsumers" of solution 1 (SEDA).

如果我不将任何参数传递给方法线程，方法2和3的行为是否相同?

If I don't pass any parameters to the method thread will the behavior of methods 2 and 3 be the same ?

预先感谢

致谢

推荐答案

您可以在1)，3)中设置线程号，但是1)仍然可以从其他路由接收消息，就像from(xxx).to ("seda:B"). 2)您需要设置ExecutorService(或ThreadPool)，否则parallelProcessing将无法正常工作.

You can setup the thread number in 1), 3), but 1) can still receive the message from other route which just like from(xxx).to("seda:B"). 2) You need to setup the ExecutorService (or ThreadPool), otherwise the parallelProcessing won't work as you want.
