Package database is an auto-generated package for the Cloud Spanner Database Admin API.

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 BackupIterator added in v1.3.0 

type BackupIterator 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 []*databasepb.Backup, nextPageToken string, err error)
	// contains filtered or unexported fields
}

BackupIterator manages a stream of *databasepb.Backup.

func (*BackupIterator) Next added in v1.3.0 

func (it *BackupIterator) Next() (*databasepb.Backup, 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.

NewDatabaseAdminClient creates a new database admin client.

Cloud Spanner Database Admin API

The Cloud Spanner Database Admin API can be used to create, drop, and list databases. It also enables updating the schema of pre-existing databases. It can be also used to create, delete and list backups for a database and to restore from an existing backup.

Example 
package main

import (
	"context"

	database "cloud.google.com/go/spanner/admin/database/apiv1"
)

func main() {
	ctx := context.Background()
	c, err := database.NewDatabaseAdminClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use client.
	_ = c
}

Output:

func (*DatabaseAdminClient) Close 

func (c *DatabaseAdminClient) Close() error

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

func (*DatabaseAdminClient) Connection 

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

Connection returns a connection to the API service.

Deprecated.

func (*DatabaseAdminClient) CreateBackup added in v1.3.0 

func (c *DatabaseAdminClient) CreateBackup(ctx context.Context, req *databasepb.CreateBackupRequest, opts ...gax.CallOption) (*CreateBackupOperation, error)

CreateBackup starts creating a new Cloud Spanner Backup. The returned backup [long-running operation][google.longrunning.Operation] will have a name of the format projects/<project>/instances/<instance>/backups/<backup>/operations/<operation_id> and can be used to track creation of the backup. The metadata field type is CreateBackupMetadata. The response field type is Backup, if successful. Cancelling the returned operation will stop the creation and delete the backup. There can be only one pending backup creation per database. Backup creation of different databases can run concurrently.

Example 
package main

import (
	"context"

	database "cloud.google.com/go/spanner/admin/database/apiv1"

	databasepb "google.golang.org/genproto/googleapis/spanner/admin/database/v1"
)

func main() {
	// import databasepb "google.golang.org/genproto/googleapis/spanner/admin/database/v1"

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

	req := &databasepb.CreateBackupRequest{
		// TODO: Fill request struct fields.
	}
	op, err := c.CreateBackup(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}

	resp, err := op.Wait(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*DatabaseAdminClient) CreateBackupOperation added in v1.3.0 

func (c *DatabaseAdminClient) CreateBackupOperation(name string) *CreateBackupOperation

CreateBackupOperation returns a new CreateBackupOperation from a given name. The name must be that of a previously created CreateBackupOperation, possibly from a different process.

func (*DatabaseAdminClient) CreateDatabase 

func (c *DatabaseAdminClient) CreateDatabase(ctx context.Context, req *databasepb.CreateDatabaseRequest, opts ...gax.CallOption) (*CreateDatabaseOperation, error)

CreateDatabase creates a new Cloud Spanner database and starts to prepare it for serving. The returned [long-running operation][google.longrunning.Operation] will have a name of the format <database_name>/operations/<operation_id> and can be used to track preparation of the database. The metadata field type is CreateDatabaseMetadata. The response field type is Database, if successful.

Example 
package main

import (
	"context"

	database "cloud.google.com/go/spanner/admin/database/apiv1"

	databasepb "google.golang.org/genproto/googleapis/spanner/admin/database/v1"
)

func main() {
	// import databasepb "google.golang.org/genproto/googleapis/spanner/admin/database/v1"

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

	req := &databasepb.CreateDatabaseRequest{
		// TODO: Fill request struct fields.
	}
	op, err := c.CreateDatabase(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}

	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*DatabaseAdminClient) CreateDatabaseOperation 

func (c *DatabaseAdminClient) CreateDatabaseOperation(name string) *CreateDatabaseOperation

func (*DatabaseAdminClient) CreateDatabaseWithRetry added in v1.6.0 

func (c *DatabaseAdminClient) CreateDatabaseWithRetry(ctx context.Context, req *databasepb.CreateDatabaseRequest, opts ...gax.CallOption) (*CreateDatabaseOperation, error)

CreateDatabaseWithRetry creates a new database and retries the call if the backend returns a retryable error. The actual CreateDatabase RPC is only retried if the initial call did not reach the server. In other cases, the client will query the backend for the long-running operation that was created by the initial RPC and return that operation.

func (*DatabaseAdminClient) DeleteBackup added in v1.3.0 

func (c *DatabaseAdminClient) DeleteBackup(ctx context.Context, req *databasepb.DeleteBackupRequest, opts ...gax.CallOption) error

Output:

func (*DatabaseAdminClient) RestoreDatabase added in v1.3.0 

func (c *DatabaseAdminClient) RestoreDatabase(ctx context.Context, req *databasepb.RestoreDatabaseRequest, opts ...gax.CallOption) (*RestoreDatabaseOperation, error)

RestoreDatabase create a new database by restoring from a completed backup. The new database must be in the same project and in an instance with the same instance configuration as the instance containing the backup. The returned database [long-running operation][google.longrunning.Operation] has a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id>, and can be used to track the progress of the operation, and to cancel it. The metadata field type is RestoreDatabaseMetadata. The response type is Database, if successful. Cancelling the returned operation will stop the restore and delete the database. There can be only one database being restored into an instance at a time. Once the restore operation completes, a new restore operation can be initiated, without waiting for the optimize operation associated with the first restore to complete.

func (*DatabaseAdminClient) SetIamPolicy 

func (c *DatabaseAdminClient) SetIamPolicy(ctx context.Context, req *iampb.SetIamPolicyRequest, opts ...gax.CallOption) (*iampb.Policy, error)

SetIamPolicy sets the access control policy on a database or backup resource. Replaces any existing policy.

Authorization requires spanner.databases.setIamPolicy permission on resource. For backups, authorization requires spanner.backups.setIamPolicy permission on resource.

Example 
package main

import (
	"context"

	database "cloud.google.com/go/spanner/admin/database/apiv1"

	iampb "google.golang.org/genproto/googleapis/iam/v1"
)

func main() {
	// import iampb "google.golang.org/genproto/googleapis/iam/v1"

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

	req := &iampb.SetIamPolicyRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.SetIamPolicy(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (c *DatabaseAdminClient) StartBackupOperation(ctx context.Context, backupID string, databasePath string, expireTime time.Time, opts ...gax.CallOption) (*CreateBackupOperation, error)

StartBackupOperation creates a backup of the given database. It will be stored as projects/<project>/instances/<instance>/backups/<backupID>. The backup will be automatically deleted by Cloud Spanner after its expiration.

backupID must be unique across an instance.

expireTime is the time the backup will expire. It is respected to microsecond granularity.

databasePath must have the form projects/<project>/instances/<instance>/databases/<database>.

func (*DatabaseAdminClient) TestIamPermissions 

func (c *DatabaseAdminClient) TestIamPermissions(ctx context.Context, req *iampb.TestIamPermissionsRequest, opts ...gax.CallOption) (*iampb.TestIamPermissionsResponse, error)

TestIamPermissions returns permissions that the caller has on the specified database or backup resource.

Attempting this RPC on a non-existent Cloud Spanner database will result in a NOT_FOUND error if the user has spanner.databases.list permission on the containing Cloud Spanner instance. Otherwise returns an empty set of permissions. Calling this method on a backup that does not exist will result in a NOT_FOUND error if the user has spanner.backups.list permission on the containing instance.

Example 
package main

import (
	"context"

	database "cloud.google.com/go/spanner/admin/database/apiv1"

	iampb "google.golang.org/genproto/googleapis/iam/v1"
)

func main() {
	// import iampb "google.golang.org/genproto/googleapis/iam/v1"

		// TODO: Fill request struct fields.
	}
	resp, err := c.TestIamPermissions(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
