SettingDescription
Regional Endpoint

A regional endpoint handles execution details for your

D s dataflow
job, its location determines where the
D s dataflow
job is executed.

Zone

A sub-section of region, a zone contains specific resources for a given region.

Select Auto Zone to allow the platform to choose the zone for you.

Machine Type

Choose the type of machine on which to run your job. The default is n1-standard-1.

SettingDescription
VPC Network mode

If the network mode is set to Auto (default), the job is executed over publicly available IP addresses. Do not set values for Network, Subnetwork, and Worker IP address configuration.

As needed, you can override the default settings configured for your project for this job. Set this value to Custom.

Info

NOTE: Avoid applying overrides unless necessary. These network settings apply to job execution. Preview and sampling use the default network settings.

  1. Specify the name of the VPC network in your region.
  2. Specify the short or full URL of the Subnetwork. If both Network and Subnetwork are specified, Subnetwork is used. See https://cloud.google.com/dataflow/docs/guides/specifying-networks.
  3. Review and specify the Worker IP address configuration setting. See below.

For more information:

NetworkTo use a different VPC network, enter the name of the VPC network to use as an override for this job. Click Save to apply the override.
Subnetwork

To specify a different subnetwork, enter the URL of the subnetwork. The URL should be in the following format:

Code Block
regions/<REGION>/subnetworks/<SUBNETWORK>

where:

  • <REGION> is the region identifier specified under Regional Endpoint. These values must match.
  • <SUBNETWORK> is the subnetwork identifier.

SettingDescription
Worker IP address configuration

If the VPC Network mode is set to custom, then choose one of the following:

  • Allow public IP addresses - Use
    D s dataflow
    workers that are available through public IP addresses. No further configuration is required.
  • Use internal IP addresses only -
    D s dataflow
    workers use private IP addresses for all communication.
    • If a Subnetwork is specified, then the Network value is ignored.
    • The specified Network or Subnetwork must have Private Google Access enabled.
Autoscaling Algorithms

The type of algorithm to use to scale the number of Google Compute Engine instances to accommodate the size of your job. Possible values:

  • Throughput based - Scaling is determined by the volume of data expected to be passed through
    D s dataflow
    .
  • None - None algorithm is applied.
    • If none is selected, use initial number of workers to specify a fixed number of Google Compute Engine instances.
Initial number of workersNumber of Google Compute Engine instances with which to launch the job. This number may be adjusted as part of job execution. This number must be an integer between 1 and 1000, inclusive.
Maximum number of workers

Maximum number of Google Compute Engine instances to use during execution. This value must be greater than the initial number of workers and must be an integer between 1 and 1000 , inclusive.

Service accountEmail address of the

Every

D s product
job executed in
D s dataflow
requires that the job be submitted through a service account. By default,
D s product
uses a default Compute Engine service account under which to run jobs.

Optionally, you can specify a different service account under which to run your job.

Info

NOTE: When using a named service account to access data and run jobs in other projects, the user running the job must be granted the roles/iam.serviceAccountUser role on the service account to use it.

For more information on service account usage and requirements, see Google Service Account Management

Labels

Create or assign labels to apply to the billing for the

D s product
jobs run in your project. You may reference up to 64 labels.

Info

NOTE: Each label must have a unique key name.
