Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the WorkflowTemplateService Client class.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns
Example 
# Modify the configuration for all WorkflowTemplateService clients

  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the WorkflowTemplateService Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

#instantiate_inline_workflow_template

def instantiate_inline_workflow_template(request, options = nil) -> ::Gapic::Operation
def instantiate_inline_workflow_template(parent: nil, template: nil, request_id: nil) -> ::Gapic::Operation

Instantiates a template and begins execution.

This method is equivalent to executing the sequence CreateWorkflowTemplate, InstantiateWorkflowTemplate, DeleteWorkflowTemplate.

The returned Operation can be used to track execution of workflow by polling operations.get. The Operation will complete when entire workflow is finished.

The running workflow can be aborted via operations.cancel. This will cause any inflight jobs to be cancelled and workflow-owned clusters to be deleted.

The Operation.metadata will be WorkflowMetadata. Also see Using WorkflowMetadata.

On successful completion, Operation.response will be Empty.

Overloads 
def instantiate_inline_workflow_template(request, options = nil) -> ::Gapic::Operation
Pass arguments to instantiate_inline_workflow_template via a request object, either of type InstantiateInlineWorkflowTemplateRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Dataproc::V1::InstantiateInlineWorkflowTemplateRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def instantiate_inline_workflow_template(parent: nil, template: nil, request_id: nil) -> ::Gapic::Operation
Pass arguments to instantiate_inline_workflow_template via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) —

    Required. The resource name of the region or location, as described in https://cloud.google.com/apis/design/resource_names.

    • For projects.regions.workflowTemplates,instantiateinline, the resource name of the region has the following format: projects/{project_id}/regions/{region}

    • For projects.locations.workflowTemplates.instantiateinline, the resource name of the location has the following format: projects/{project_id}/locations/{location}

  • template (::Google::Cloud::Dataproc::V1::WorkflowTemplate, ::Hash) — Required. The workflow template to instantiate.
  • request_id (::String) — Optional. A tag that prevents multiple concurrent workflow instances with the same tag from running. This mitigates risk of concurrent instances started due to retries.

    It is recommended to always set this value to a UUID.

    The tag must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters.

Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)
Returns
  • (::Gapic::Operation)
Raises
