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

Cloud Spanner is a managed, mission-critical, globally consistent and scalable relational database service.

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.

// go get cloud.google.com/go/spanner/admin/database/apiv1@latest
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 := database.NewDatabaseAdminClient(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, mentioned above.

req := &databasepb.AddSplitPointsRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/spanner/admin/database/apiv1/databasepb#AddSplitPointsRequest.
}
resp, err := c.AddSplitPoints(ctx, req)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewDatabaseAdminClient 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.

BackupIterator

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) All 

func (it *BackupIterator) All() iter.Seq2[*databasepb.Backup, error]

All returns an iterator. If an error is returned by the iterator, the iterator will stop after that iteration.

func (*BackupIterator) Next 

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.

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

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

BackupScheduleIterator

type BackupScheduleIterator struct {
