Reference documentation and code samples for the Google Cloud Dataflow V1beta3 Client class WorkerPool.

Describes one particular pool of Cloud Dataflow workers to be instantiated by the Cloud Dataflow service in order to perform the computations required by a job. Note that a workflow job may use multiple pools, in order to match the various computational requirements of the various stages of the job.

Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ kind	string The kind of the worker pool; currently only harness and shuffle are supported.
↳ num_workers	int Number of Google Compute Engine workers in this pool needed to execute the job. If zero or unspecified, the service will attempt to choose a reasonable default.
↳ packages	array<Google\Cloud\Dataflow\V1beta3\Package> Packages to be installed on workers.
↳ default_package_set	int The default package set to install. This allows the service to select a default set of packages which are useful to worker harnesses written in a particular language.
↳ machine_type	string Machine type (e.g. "n1-standard-1"). If empty or unspecified, the service will attempt to choose a reasonable default.
↳ teardown_policy	int Sets the policy for determining when to turndown worker pool. Allowed values are: TEARDOWN_ALWAYS, TEARDOWN_ON_SUCCESS, and TEARDOWN_NEVER. TEARDOWN_ALWAYS means workers are always torn down regardless of whether the job succeeds. TEARDOWN_ON_SUCCESS means workers are torn down if the job succeeds. TEARDOWN_NEVER means the workers are never torn down. If the workers are not torn down by the service, they will continue to run and use Google Compute Engine VM resources in the user's project until they are explicitly terminated by the user. Because of this, Google recommends using the TEARDOWN_ALWAYS policy except for small, manually supervised test jobs. If unknown or unspecified, the service will attempt to choose a reasonable default.
↳ disk_size_gb	int Size of root disk for VMs, in GB. If zero or unspecified, the service will attempt to choose a reasonable default.
↳ disk_type	string Type of root disk for VMs. If empty or unspecified, the service will attempt to choose a reasonable default.
↳ disk_source_image	string Fully qualified source image for disks.
↳ zone	string Zone to run the worker pools in. If empty or unspecified, the service will attempt to choose a reasonable default.
↳ taskrunner_settings	Google\Cloud\Dataflow\V1beta3\TaskRunnerSettings Settings passed through to Google Compute Engine workers when using the standard Dataflow task runner. Users should ignore this field.
↳ on_host_maintenance	string The action to take on host maintenance, as defined by the Google Compute Engine API.
↳ data_disks	array<Google\Cloud\Dataflow\V1beta3\Disk> Data disks that are used by a VM in this workflow.
↳ metadata	array|Google\Protobuf\Internal\MapField Metadata to set on the Google Compute Engine VMs.
↳ autoscaling_settings	Google\Cloud\Dataflow\V1beta3\AutoscalingSettings Settings for autoscaling of this WorkerPool.
↳ pool_args	Google\Protobuf\Any Extra arguments for this worker pool.
↳ network	string Network to which VMs will be assigned. If empty or unspecified, the service will use the network "default".
↳ subnetwork	string Subnetwork to which VMs will be assigned, if desired. Expected to be of the form "regions/REGION/subnetworks/SUBNETWORK".
↳ worker_harness_container_image	string Required. Docker container image that executes the Cloud Dataflow worker harness, residing in Google Container Registry. Deprecated for the Fn API path. Use sdk_harness_container_images instead.
↳ num_threads_per_worker	int The number of threads per worker harness. If empty or unspecified, the service will choose a number of threads (according to the number of cores on the selected machine type for batch, or 1 by convention for streaming).
↳ ip_configuration	int Configuration for VM IPs.
↳ sdk_harness_container_images	array<Google\Cloud\Dataflow\V1beta3\SdkHarnessContainerImage> Set of SDK harness containers needed to execute this pipeline. This will only be set in the Fn API path. For non-cross-language pipelines this should have only one entry. Cross-language pipelines will have two or more entries.
