Overview

Package admin is an auto-generated package for the Cloud Datastore API.

Accesses the schemaless NoSQL database to provide fully managed, robust, scalable storage for your application.

NOTE: This package is in alpha. It is not stable, and is likely to change.

Example usage

To get started with this package, create a client.

ctx := context.Background()
c, err := admin.NewDatastoreAdminClient(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()
c, err := admin.NewDatastoreAdminClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

req := &adminpb.ExportEntitiesRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/google.golang.org/genproto/googleapis/datastore/admin/v1#ExportEntitiesRequest.
}
op, err := c.ExportEntities(ctx, req)
if err != nil {
	// TODO: Handle error.
}

resp, err := op.Wait(ctx)
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.

Types

type CreateIndexOperation added in v1.5.0

type CreateIndexOperation struct {
	// contains filtered or unexported fields
}

CreateIndexOperation manages a long-running operation from CreateIndex.

func (*CreateIndexOperation) Done added in v1.5.0

func (op *CreateIndexOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*CreateIndexOperation) Metadata added in v1.5.0

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*CreateIndexOperation) Name added in v1.5.0

func (op *CreateIndexOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*CreateIndexOperation) Poll added in v1.5.0

func (op *CreateIndexOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*adminpb.Index, error)

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*CreateIndexOperation) Wait added in v1.5.0

func (op *CreateIndexOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*adminpb.Index, error)

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

type DatastoreAdminCallOptions

type DatastoreAdminCallOptions struct {
	ExportEntities  []gax.CallOption
	ImportEntities  []gax.CallOption
	CreateIndex     []gax.CallOption
	DeleteIndex     []gax.CallOption
	GetIndex        []gax.CallOption
	ListIndexes     []gax.CallOption
	CancelOperation []gax.CallOption
	DeleteOperation []gax.CallOption
	GetOperation    []gax.CallOption
	ListOperations  []gax.CallOption
}

DatastoreAdminCallOptions contains the retry settings for each method of DatastoreAdminClient.

type DatastoreAdminClient

type DatastoreAdminClient struct {

	// The call options for this service.
	CallOptions *DatastoreAdminCallOptions

	// LROClient is used internally to handle long-running operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient
	// contains filtered or unexported fields
}

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

Google Cloud Datastore Admin API

The Datastore Admin API provides several admin services for Cloud Datastore.

ConceptsProject, namespace, kind, and entity as defined in the Google Cloud Datastore API.

Operation: An Operation represents work being performed in the background.

EntityFilter: Allows specifying a subset of entities in a project. This is specified as a combination of kinds and namespaces (either or both of which may be all).

ServicesExport/ImportThe Export/Import service provides the ability to copy all or a subset of entities to/from Google Cloud Storage.

Exported data may be imported into Cloud Datastore for any Google Cloud Platform project. It is not restricted to the export source project. It is possible to export from one project and then import into another.

Exported data can also be loaded into Google BigQuery for analysis.

Exports and imports are performed asynchronously. An Operation resource is created for each export/import. The state (including any errors encountered) of the export/import may be queried via the Operation resource.

IndexThe index service manages Cloud Datastore composite indexes.

Index creation and deletion are performed asynchronously. An Operation resource is created for each such asynchronous operation. The state of the operation (including any errors encountered) may be queried via the Operation resource.

OperationThe Operations collection provides a record of actions performed for the specified project (including any operations in progress). Operations are not created directly but through calls on other collections or resources.

An operation that is not yet done may be cancelled. The request to cancel is asynchronous and the operation may continue to run for some time after the request to cancel is made.

An operation that is done may be deleted so that it is no longer listed as part of the Operation collection.

ListOperations returns all pending operations, but not completed operations.

Operations are created by service DatastoreAdmin, but are accessed via service google.longrunning.Operations.

func NewDatastoreAdminClient

func NewDatastoreAdminClient(ctx context.Context, opts ...option.ClientOption) (*DatastoreAdminClient, error)

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

Example
package main

import (
	"context"

	admin "cloud.google.com/go/datastore/admin/apiv1"
)

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

	// TODO: Use client.
	_ = c
}
Output:

func (*DatastoreAdminClient) CancelOperation added in v1.8.0

CancelOperation is a utility method from google.longrunning.Operations.

Example
package main

import (
	"context"

	admin "cloud.google.com/go/datastore/admin/apiv1"
	longrunningpb "google.golang.org/genproto/googleapis/longrunning"
)

func main() {
	ctx := context.Background()
	c, err := admin.NewDatastoreAdminClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &longrunningpb.CancelOperationRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/google.golang.org/genproto/googleapis/longrunning#CancelOperationRequest.
	}
	err = c.CancelOperation(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
}
Output:

func (*DatastoreAdminClient) Close

func (c *DatastoreAdminClient) Close() error

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

func (*DatastoreAdminClient) Connection

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

Connection returns a connection to the API service.

Deprecated.

func (*DatastoreAdminClient) CreateIndex added in v1.5.0

CreateIndex creates the specified index. A newly created index’s initial state is CREATING. On completion of the returned google.longrunning.Operation, the state will be READY. If the index already exists, the call will return an ALREADY_EXISTS status.

During index creation, the process could result in an error, in which case the index will move to the ERROR state. The process can be recovered by fixing the data that caused the error, removing the index with delete, then re-creating the index with [create] [google.datastore.admin.v1.DatastoreAdmin.CreateIndex].

Indexes with a single property cannot be created.

Example
package main

import (
	"context"

	admin "cloud.google.com/go/datastore/admin/apiv1"
	adminpb "google.golang.org/genproto/googleapis/datastore/admin/v1"
)

func main() {
	ctx := context.Background()
	c, err := admin.NewDatastoreAdminClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &adminpb.CreateIndexRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/google.golang.org/genproto/googleapis/datastore/admin/v1#CreateIndexRequest.
	}
	op, err := c.CreateIndex(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 (*DatastoreAdminClient) CreateIndexOperation added in v1.5.0

func (c *DatastoreAdminClient) CreateIndexOperation(name string) *CreateIndexOperation

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

func (*DatastoreAdminClient) DeleteIndex added in v1.5.0

DeleteIndex deletes an existing index. An index can only be deleted if it is in a READY or ERROR state. On successful execution of the request, the index will be in a DELETING state. And on completion of the returned google.longrunning.Operation, the index will be removed.

During index deletion, the process could result in an error, in which case the index will move to the ERROR state. The process can be recovered by fixing the data that caused the error, followed by calling delete again.

Example
package main

import (
	"context"

	admin "cloud.google.com/go/datastore/admin/apiv1"
	adminpb "google.golang.org/genproto/googleapis/datastore/admin/v1"
)

func main() {
	ctx := context.Background()
	c, err := admin.NewDatastoreAdminClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &adminpb.DeleteIndexRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/google.golang.org/genproto/googleapis/datastore/admin/v1#DeleteIndexRequest.

	}
	err = c.DeleteOperation(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
}
Output:

func (*DatastoreAdminClient) ExportEntities

ExportEntities exports a copy of all or a subset of entities from Google Cloud Datastore to another storage system, such as Google Cloud Storage. Recent updates to entities may not be reflected in the export. The export occurs in the background and its progress can be monitored and managed via the Operation resource that is created. The output of an export may only be used once the associated operation is done. If an export operation is cancelled before completion it may leave partial data behind in Google Cloud Storage.

Example
package main

import (
	"context"

	admin "cloud.google.com/go/datastore/admin/apiv1"
	adminpb "google.golang.org/genproto/googleapis/datastore/admin/v1"

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

func (*DatastoreAdminClient) ListIndexes

ListIndexes lists the indexes that match the specified filters. Datastore uses an eventually consistent query to fetch the list of indexes and may occasionally return stale results.

Example
package main

import (
	"context"

	admin "cloud.google.com/go/datastore/admin/apiv1"
	"google.golang.org/api/iterator"
