Documentation

Overview

Package migration is an auto-generated package for the BigQuery Migration API.

The migration service, exposing apis for migration jobs operations, and agent management. 

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

req := &migrationpb.CreateMigrationWorkflowRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/cloud.google.com/go/bigquery/migration/apiv2/migrationpb#CreateMigrationWorkflowRequest.
}
resp, err := c.CreateMigrationWorkflow(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewClient 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.

Functions

func DefaultAuthScopes 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type CallOptions 

type CallOptions struct {
	CreateMigrationWorkflow []gax.CallOption
	GetMigrationWorkflow    []gax.CallOption
	ListMigrationWorkflows  []gax.CallOption
	DeleteMigrationWorkflow []gax.CallOption
	StartMigrationWorkflow  []gax.CallOption
	GetMigrationSubtask     []gax.CallOption
	ListMigrationSubtasks   []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client 

type Client struct {

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

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

Service to handle EDW migrations.

func NewClient 

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

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

Service to handle EDW migrations.

Example 
package main

import (
	"context"

	migration "cloud.google.com/go/bigquery/migration/apiv2"
)

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

	// TODO: Use client.
	_ = c
}

Output:

func (*Client) Close 

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) Connection deprecated 

func (c *Client) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.

func (*Client) CreateMigrationWorkflow 

func (c *Client) CreateMigrationWorkflow(ctx context.Context, req *migrationpb.CreateMigrationWorkflowRequest, opts ...gax.CallOption) (*migrationpb.MigrationWorkflow, error)

CreateMigrationWorkflow creates a migration workflow.

Example 
package main

import (
	"context"

	migration "cloud.google.com/go/bigquery/migration/apiv2"
	migrationpb "cloud.google.com/go/bigquery/migration/apiv2/migrationpb"
)

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

	req := &migrationpb.CreateMigrationWorkflowRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/bigquery/migration/apiv2/migrationpb#CreateMigrationWorkflowRequest.
	}
	resp, err := c.CreateMigrationWorkflow(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Client) DeleteMigrationWorkflow 

func (c *Client) DeleteMigrationWorkflow(ctx context.Context, req *migrationpb.DeleteMigrationWorkflowRequest, opts ...gax.CallOption) error

DeleteMigrationWorkflow deletes a migration workflow by name.

		// TODO: Handle error.
	}
}

Output:

type MigrationSubtaskIterator 

type MigrationSubtaskIterator 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{}

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

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

func (it *MigrationWorkflowIterator) Next() (*migrationpb.MigrationWorkflow, 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.
