什么是默认的Akka调度程序配置值？

Question

在Akka文档中,它指出如果未配置调度程序,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？

Answer 1

默认情况下,提供的调度程序Akka是带有a 的调度程序fork-join-executor,默认的并行度值是:

• parallelism-min: 8
• 并行因子: 3.0
• parallelism-max: 64

您可以在文档中看到所有这些内容.

有一个名为的部分:参考配置列表

这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
    }

    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
    }
}
