Akka调度程序的默认配置值是什么？ [英] What are the default Akka dispatcher configuration values?

问题描述

在Akka文档中指出，如果未配置调度程序，则将使用默认调度程序。默认调度程序的属性是什么，即parallelism-min，parallelism-factor，parallelism-max等？？

解决方案

默认 Akka 提供的调度程序是带有 fork-join-executor 的调度程序，默认并行度值为： / p>

• 并行度最小值： 8


• 并行度系数： 3.0


• parallelism-max： 64

您可以在文档中看到所有这些内容。

有一个节名为： 列出参考配置

以下是配置文件的相关部分（我只删除了注释）：

  default-dispatcher { 
 type = Dispatcher 
 executor = fork-join-executor 
 
 fork-join-executor {
 parallelism-min = 8 
 parallelism -factor = 3.0 
 parallelism-max = 64 
} 
 
线程池执行器{
 keep-alive-time = 60s 
 core-pool -size-min = 8 
核心池大小系数= 3.0 
 core-pool-size-max = 64 
 max-pool-size-min = 8 
 max -pool-size-factor = 3.0 
 max-pool-size-max = 64 
任务队列大小= -1 
任务队列类型=链接 
 
 allow-core-timeout = on 
} 
} 
  

In the Akka documentation it states that if a dispatcher is not configured a default dispatcher will be used. What are the properties of the default dispatcher i.e parallelism-min, parallelism-factor, parallelism-max etc. ?

解决方案

By default the dispatcher provided by Akka is one with a fork-join-executor, and the default parallelism values are these:

• parallelism-min: 8
• parallelism-factor: 3.0
• parallelism-max: 64

You can see all of this in the documentation.

There is a section named: Listing of the Reference Configuration

Here is the relevant part of the configuration file (I only removed the comments):

default-dispatcher {
    type = "Dispatcher"
    executor = "fork-join-executor"

    fork-join-executor {
        parallelism-min = 8
        parallelism-factor = 3.0
        parallelism-max = 64
    }

    thread-pool-executor {
        keep-alive-time = 60s
        core-pool-size-min = 8
        core-pool-size-factor = 3.0
        core-pool-size-max = 64
        max-pool-size-min = 8
        max-pool-size-factor  = 3.0
        max-pool-size-max = 64
        task-queue-size = -1
        task-queue-type = "linked"

        allow-core-timeout = on
    }
}
