Overview

Package reservation is an auto-generated package for the BigQuery Reservation API.

A service to modify your BigQuery flat-rate reservations.

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.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

Types

type AssignmentIterator

type AssignmentIterator 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 []*reservationpb.Assignment, nextPageToken string, err error)
	// contains filtered or unexported fields
}

AssignmentIterator manages a stream of *reservationpb.Assignment.

func (*AssignmentIterator) Next

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 (*AssignmentIterator) PageInfo

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

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

type CallOptions

type CallOptions struct {
	CreateReservation        []gax.CallOption
	ListReservations         []gax.CallOption
	GetReservation           []gax.CallOption
	DeleteReservation        []gax.CallOption

	MoveAssignment           []gax.CallOption
	GetBiReservation         []gax.CallOption
	UpdateBiReservation      []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type CapacityCommitmentIterator

type CapacityCommitmentIterator 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 []*reservationpb.CapacityCommitment, nextPageToken string, err error)
	// contains filtered or unexported fields
}

CapacityCommitmentIterator manages a stream of *reservationpb.CapacityCommitment.

func (*CapacityCommitmentIterator) Next

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 (*CapacityCommitmentIterator) PageInfo

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

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 Reservation API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewClient

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

NewClient creates a new reservation service client.

This API allows users to manage their flat-rate BigQuery reservations.

A reservation provides computational resource guarantees, in the form of slots (at https://cloud.google.com/bigquery/docs/slots), to users. A slot is a unit of computational power in BigQuery, and serves as the basic unit of parallelism. In a scan of a multi-partitioned table, a single slot operates on a single partition of the table. A reservation resource exists as a child resource of the admin project and location, e.g.: projects/myproject/locations/US/reservations/reservationName.

A capacity commitment is a way to purchase compute capacity for BigQuery jobs (in the form of slots) with some committed period of usage. A capacity commitment resource exists as a child resource of the admin project and location, e.g.: projects/myproject/locations/US/capacityCommitments/id.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
)

func main() {
	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// 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

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

Connection returns a connection to the API service.

Deprecated.

func (*Client) CreateAssignment

CreateAssignment creates an assignment object which allows the given project to submit jobs of a certain type using slots from the specified reservation.

Currently a resource (project, folder, organization) can only have one assignment per each (job_type, location) combination, and that reservation will be used for all jobs of the matching type.

Different assignments can be created on different levels of the projects, folders or organization hierarchy. During query execution, the assignment is looked up at the project, folder and organization levels in that order. The first assignment found is applied to the query.

When creating assignments, it does not matter if other assignments exist at higher levels.

Example:

The organization organizationA contains two projects, project1
and project2.

Assignments for all three entities (organizationA, project1, and
project2) could all be created and mapped to the same or different
reservations.

Returns google.rpc.Code.PERMISSION_DENIED if user does not have ‘bigquery.admin’ permissions on the project using the reservation and the project that owns this reservation.

Returns google.rpc.Code.INVALID_ARGUMENT when location of the assignment does not match location of the reservation.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.CreateAssignmentRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.CreateAssignment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) CreateCapacityCommitment

CreateCapacityCommitment creates a new capacity commitment resource.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.CreateCapacityCommitmentRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.CreateCapacityCommitment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) CreateReservation

CreateReservation creates a new reservation resource.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()

	_ = resp
}
Output:

func (*Client) DeleteAssignment

func (c *Client) DeleteAssignment(ctx context.Context, req *reservationpb.DeleteAssignmentRequest, opts ...gax.CallOption) error

DeleteAssignment deletes a assignment. No expansion will happen.

Example:

Organization organizationA contains two projects, project1 and
project2.

Reservation res1 exists and was created previously.

CreateAssignment was used previously to define the following
associations between entities and reservations: <organizationA, res1>
and <project1, res1>

In this example, deletion of the <organizationA, res1> assignment won’t affect the other assignment <project1, res1>. After said deletion, queries from project1 will still use res1 while queries from project2 will switch to use on-demand mode.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.DeleteAssignmentRequest{
		// TODO: Fill request struct fields.
	}
	err = c.DeleteAssignment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
}
Output:

func (*Client) DeleteCapacityCommitment

func (c *Client) DeleteCapacityCommitment(ctx context.Context, req *reservationpb.DeleteCapacityCommitmentRequest, opts ...gax.CallOption) error

DeleteCapacityCommitment deletes a capacity commitment. Attempting to delete capacity commitment before its commitment_end_time will fail with the error code google.rpc.Code.FAILED_PRECONDITION.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.DeleteCapacityCommitmentRequest{
		// TODO: Fill request struct fields.
	}
	err = c.DeleteCapacityCommitment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
}
Output:

func (*Client) DeleteReservation

func (c *Client) DeleteReservation(ctx context.Context, req *reservationpb.DeleteReservationRequest, opts ...gax.CallOption) error

DeleteReservation deletes a reservation. Returns google.rpc.Code.FAILED_PRECONDITION when reservation has assignments.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.DeleteReservationRequest{
		// TODO: Fill request struct fields.
	}
	err = c.DeleteReservation(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
}
Output:

func (*Client) GetBiReservation

GetBiReservation retrieves a BI reservation.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.GetBiReservationRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.GetBiReservation(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) GetCapacityCommitment

GetCapacityCommitment returns information about the capacity commitment.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.

Output:

func (*Client) GetReservation

GetReservation returns information about the reservation.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) ListAssignments

ListAssignments lists assignments.

Only explicitly created assignments will be returned.

Example:

Organization organizationA contains two projects, project1 and
project2.

Reservation res1 exists and was created previously.

CreateAssignment was used previously to define the following
associations between entities and reservations: <organizationA, res1>
and <project1, res1>

In this example, ListAssignments will just return the above two assignments for reservation res1, and no expansion/merge will happen.

The wildcard “-” can be used for reservations in the request. In that case all assignments belongs to the specified project and location will be listed.

Note "-" cannot be used for projects nor locations.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	"google.golang.org/api/iterator"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
	// import "google.golang.org/api/iterator"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.ListAssignmentsRequest{
		// TODO: Fill request struct fields.
	}
	it := c.ListAssignments(ctx, req)
	for {
		resp, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			// TODO: Handle error.
		}
		// TODO: Use resp.
		_ = resp
	}
}
Output:

func (*Client) ListCapacityCommitments

ListCapacityCommitments lists all the capacity commitments for the admin project.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	"google.golang.org/api/iterator"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
	// import "google.golang.org/api/iterator"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.ListCapacityCommitmentsRequest{
		// TODO: Fill request struct fields.
	}
	it := c.ListCapacityCommitments(ctx, req)
	for {
		resp, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			// TODO: Handle error.
		}
		// TODO: Use resp.
		_ = resp
	}
}
Output:

func (*Client) ListReservations

ListReservations lists all the reservations for the project in the specified location.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	"google.golang.org/api/iterator"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
	// import "google.golang.org/api/iterator"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.ListReservationsRequest{
		// TODO: Fill request struct fields.
	}
	it := c.ListReservations(ctx, req)
	for {
		resp, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			// TODO: Handle error.
		}
		// TODO: Use resp.
		_ = resp
	}
}
Output:

func (*Client) MergeCapacityCommitments

MergeCapacityCommitments merges capacity commitments of the same plan into a single commitment.

The resulting capacity commitment has the greater commitment_end_time out of the to-be-merged capacity commitments.

Attempting to merge capacity commitments of different plan will fail with the error code google.rpc.Code.FAILED_PRECONDITION.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.MergeCapacityCommitmentsRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.MergeCapacityCommitments(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) MoveAssignment

MoveAssignment moves an assignment under a new reservation.

This differs from removing an existing assignment and recreating a new one by providing a transactional change that ensures an assignee always has an associated reservation.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.MoveAssignmentRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.MoveAssignment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) SearchAssignments

SearchAssignments looks up assignments for a specified resource for a particular region. If the request is about a project:

Assignments created on the project will be returned if they exist.

Otherwise assignments created on the closest ancestor will be returned.

Assignments for different JobTypes will all be returned.

The same logic applies if the request is about a folder.

If the request is about an organization, then assignments created on the organization will be returned (organization doesn’t have ancestors).

Comparing to ListAssignments, there are some behavior differences:

permission on the assignee will be verified in this API.

Hierarchy lookup (project->folder->organization) happens in this API.

Parent here is projects/*/locations/*, instead of projects/*/locations/*reservations/*.

Note "-" cannot be used for projects nor locations.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	"google.golang.org/api/iterator"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
	// import "google.golang.org/api/iterator"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.SearchAssignmentsRequest{
		// TODO: Fill request struct fields.
	}
	it := c.SearchAssignments(ctx, req)
	for {
		resp, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			// TODO: Handle error.
		}
		// TODO: Use resp.
		_ = resp
	}
}
Output:

func (*Client) SplitCapacityCommitment

SplitCapacityCommitment splits capacity commitment to two commitments of the same plan and commitment_end_time.

A common use case is to enable downgrading commitments.

For example, in order to downgrade from 10000 slots to 8000, you might split a 10000 capacity commitment into commitments of 2000 and 8000. Then, you would change the plan of the first one to FLEX and then delete it.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.SplitCapacityCommitmentRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.SplitCapacityCommitment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) UpdateBiReservation

UpdateBiReservation updates a BI reservation.

Only fields specified in the field_mask are updated.

A singleton BI reservation always exists with default size 0. In order to reserve BI capacity it needs to be updated to an amount greater than 0. In order to release BI capacity reservation size must be set to 0.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"
)

func main() {
	// import reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

	ctx := context.Background()
	c, err := reservation.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &reservationpb.UpdateBiReservationRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.UpdateBiReservation(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) UpdateCapacityCommitment

UpdateCapacityCommitment updates an existing capacity commitment.

Only plan and renewal_plan fields can be updated.

Plan can only be changed to a plan of a longer commitment period. Attempting to change to a plan with shorter commitment period will fail with the error code google.rpc.Code.FAILED_PRECONDITION.

Example
package main

import (
	"context"

	reservation "cloud.google.com/go/bigquery/reservation/apiv1"
	reservationpb "google.golang.org/genproto/googleapis/cloud/bigquery/reservation/v1"

}
Output:

func (*Client) UpdateReservation

	// 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 []*reservationpb.Reservation, nextPageToken string, err error)

}

ReservationIterator manages a stream of *reservationpb.Reservation.

func (*ReservationIterator) Next

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 (*ReservationIterator) PageInfo

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

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