Documentation

Overview

Package dataflow is an auto-generated package for the Dataflow API.

Manages Google Cloud Dataflow projects on Google Cloud Platform. 

NOTE: This package is in beta. It is not stable, and may be subject to changes.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

Example usage

To get started with this package, create a client. 

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := dataflow.NewSnapshotsV1Beta3Client(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client. 

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := dataflow.NewSnapshotsV1Beta3Client(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

req := &dataflowpb.DeleteSnapshotRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/cloud.google.com/go/dataflow/apiv1beta3/dataflowpb#DeleteSnapshotRequest.
}
resp, err := c.DeleteSnapshot(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewSnapshotsV1Beta3Client is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Types

type FlexTemplatesCallOptions 

type FlexTemplatesCallOptions struct {
	LaunchFlexTemplate []gax.CallOption

FlexTemplatesCallOptions contains the retry settings for each method of FlexTemplatesClient.

type FlexTemplatesClient 

type FlexTemplatesClient struct {

	// The call options for this service.
	CallOptions *FlexTemplatesCallOptions
	// contains filtered or unexported fields
}

FlexTemplatesClient is a client for interacting with Dataflow API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Provides a service for Flex templates. This feature is not ready yet.

func NewFlexTemplatesClient 

func NewFlexTemplatesClient(ctx context.Context, opts ...option.ClientOption) (*FlexTemplatesClient, error)

NewFlexTemplatesClient creates a new flex templates service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

Provides a service for Flex templates. This feature is not ready yet.

Example 
package main

import (
	"context"

	dataflow "cloud.google.com/go/dataflow/apiv1beta3"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options

	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func (c *JobsV1Beta3Client) CreateJob(ctx context.Context, req *dataflowpb.CreateJobRequest, opts ...gax.CallOption) (*dataflowpb.Job, error)

CreateJob creates a Cloud Dataflow job.

To create a job, we recommend using projects.locations.jobs.create with a [regional endpoint] (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints (at https://cloud.google.com/dataflow/docs/concepts/regional-endpoints)). Using projects.jobs.create is not recommended, as your job will always start in us-central1.

Example 
package main

import (
	"context"

	dataflow "cloud.google.com/go/dataflow/apiv1beta3"
	dataflowpb "cloud.google.com/go/dataflow/apiv1beta3/dataflowpb"

func (*JobsV1Beta3Client) GetJob 

func (c *JobsV1Beta3Client) GetJob(ctx context.Context, req *dataflowpb.GetJobRequest, opts ...gax.CallOption) (*dataflowpb.Job, error)

GetJob gets the state of the specified Cloud Dataflow job.

To get the state of a job, we recommend using projects.locations.jobs.get with a [regional endpoint] (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints (at https://cloud.google.com/dataflow/docs/concepts/regional-endpoints)). Using projects.jobs.get is not recommended, as you can only get the state of jobs that are running in us-central1.

Output:

func (*JobsV1Beta3Client) ListJobs 

func (c *JobsV1Beta3Client) ListJobs(ctx context.Context, req *dataflowpb.ListJobsRequest, opts ...gax.CallOption) *JobIterator

ListJobs list the jobs of a project.

To list the jobs of a project in a region, we recommend using projects.locations.jobs.list with a [regional endpoint] (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints (at https://cloud.google.com/dataflow/docs/concepts/regional-endpoints)). To list the all jobs across all regions, use projects.jobs.aggregated. Using projects.jobs.list is not recommended, as you can only get the list of jobs that are running in us-central1.

Example 
package main

Output:

func (*JobsV1Beta3Client) UpdateJob 

func (c *JobsV1Beta3Client) UpdateJob(ctx context.Context, req *dataflowpb.UpdateJobRequest, opts ...gax.CallOption) (*dataflowpb.Job, error)

UpdateJob updates the state of an existing Cloud Dataflow job.

To update the state of an existing job, we recommend using projects.locations.jobs.update with a [regional endpoint] (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints (at https://cloud.google.com/dataflow/docs/concepts/regional-endpoints)). Using projects.jobs.update is not recommended, as you can only update the state of jobs that are running in us-central1.

Output:

type WorkerDetailsIterator 

type WorkerDetailsIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.
	//
	// InternalFetch returns results from a single call to the underlying RPC.
	// The number of results is no greater than pageSize.
	// If there are no more results, nextPageToken is empty and err is nil.
	InternalFetch func(pageSize int, pageToken string) (results []*dataflowpb.WorkerDetails, nextPageToken string, err error)
	// contains filtered or unexported fields
}

WorkerDetailsIterator manages a stream of *dataflowpb.WorkerDetails.

func (*WorkerDetailsIterator) Next 

func (it *WorkerDetailsIterator) Next() (*dataflowpb.WorkerDetails, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*WorkerDetailsIterator) PageInfo 

func (it *WorkerDetailsIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.
