Python Dataflow SDK中的自定义机器类型 [英] Custom Machine Types in Python Dataflow SDK

问题描述

根据>是否可以使用一个用于Dataflow实例的自定义计算机?您可以通过将名称指定为custom-<number of cpus>-<memory in mb>

According to Is it possible to use a Custom machine for Dataflow instances? you can set the custom machine type for a dataflow operation by specifying the name as custom-<number of cpus>-<memory in mb>

但是答案是针对Java Api和旧的Dataflow版本，而不是新的Apache Beam实现和Python.

But that answer is for the Java Api and the old Dataflow version, not the new Apache Beam implementation and Python.

如果我在2.0.0 google-cloud-dataflow python API中提供了--worker_machine_type custom-8-5376，则会出现以下错误:

If I supply --worker_machine_type custom-8-5376in the 2.0.0 google-cloud-dataflow python API, I get the following error:

(4092fe7df5a10577):无法创建工作流程.请在几分钟后重试.如果仍然无法创建作业，请与客户支持联系.原因:(4092fe7df5a10596):无法获取以下机器的类型信息us-central1-f区域中的计算机类型custom-8-5376.请检查计算机类型和区域是否正确."

"(4092fe7df5a10577): The workflow could not be created. Please try again in a few minutes. If you are still unable to create a job please contact customer support. Causes: (4092fe7df5a10596): Unable to get machine type information for machine type custom-8-5376 in zone us-central1-f. Please check that machine type and zone are correct."

我还尝试在计算引擎中定义一个新的实例模板，并在--worker_machine_type参数中提供该模板的名称，但这也不起作用.

I also tried defining a new instance template in the compute engine and supplying the name of that template in the --worker_machine_type parameter, but that doesn't work, either.

如何使用自定义计算机类型在Dataflow 2.0.0上运行工作流?

How can you run a workflow on Dataflow 2.0.0 with a custom machine type?

推荐答案

每个自定义计算机类型doc: https://cloud.google.com/compute/docs/instances/creating-instance-with-custom-machine-type

per custom machine type doc: https://cloud.google.com/compute/docs/instances/creating-instance-with-custom-machine-type

每个vCPU的自定义计算机类型的每个vCPU的内存必须在0.9 GB和6.5 GB之间(包括两端).

The memory per vCPU of a custom machine type must be between 0.9 GB and 6.5 GB per vCPU, inclusive.

因此对于8个vCPU，最小为7424MiB.

So for 8 vCPUs, 7424MiB is the minimum.

能否请您再试一次?
