Remarks

Google Cloud Datastore Admin API

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

Concepts: Project, 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).

Export/Import Service:

The 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.

Index Service:

The 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.

Operation Service:

The 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.

Methods

CreateIndex(CreateIndexRequest, CallSettings)

public override Operation<Index, IndexOperationMetadata> CreateIndex(CreateIndexRequest request, CallSettings callSettings = null)

Creates the specified index. A newly created index's initial state is CREATING. On completion of the returned [google.longrunning.Operation][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][google.datastore.admin.v1.DatastoreAdmin.DeleteIndex], then re-creating the index with [create] [google.datastore.admin.v1.DatastoreAdmin.CreateIndex].

Indexes with a single property cannot be created.

Parameters
Name	Description
`request`	`CreateIndexRequest` The request object containing all of the parameters for the API call.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Returns
Type	Description
`OperationIndexIndexOperationMetadata`	The RPC response.

Overrides

DatastoreAdminClient.CreateIndex(CreateIndexRequest, CallSettings)

CreateIndexAsync(CreateIndexRequest, CallSettings)

public override Task<Operation<Index, IndexOperationMetadata>> CreateIndexAsync(CreateIndexRequest request, CallSettings callSettings = null)

Indexes with a single property cannot be created.

Parameters
Name	Description
`request`	`CreateIndexRequest` The request object containing all of the parameters for the API call.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Returns
Type	Description
`TaskOperationIndexIndexOperationMetadata`	A Task containing the RPC response.

Overrides

DatastoreAdminClient.CreateIndexAsync(CreateIndexRequest, CallSettings)

DeleteIndex(DeleteIndexRequest, CallSettings)

public override Operation<Index, IndexOperationMetadata> DeleteIndex(DeleteIndexRequest request, CallSettings callSettings = null)

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][google.datastore.admin.v1.Index.State]. And on completion of the returned [google.longrunning.Operation][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][google.datastore.admin.v1.DatastoreAdmin.DeleteIndex] again.

Parameters
Name	Description
`request`	`DeleteIndexRequest` The request object containing all of the parameters for the API call.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Returns
Type	Description

ExportEntities(ExportEntitiesRequest, CallSettings)

public override Operation<ExportEntitiesResponse, ExportEntitiesMetadata> ExportEntities(ExportEntitiesRequest request, CallSettings callSettings = null)

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.
