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).

Services

Export/Import

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

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

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.

CreateIndex(CreateIndexRequest, CallSettings)

public virtual 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
`Google.LongRunning.Operation<Index, IndexOperationMetadata>`	The RPC response.

Parameters
Name	Description
`projectId`	`String` Required. Project ID against which to make the request.
`labels`	`IDictionary<String, String>` Client-assigned labels.
`entityFilter`	`EntityFilter` Description of what data from the project is included in the export.
`outputUrlPrefix`	`String` Required. Location for the export metadata and data files. The full resource URL of the external storage location. Currently, only Google Cloud Storage is supported.

public virtual Operation<Empty, ImportEntitiesMetadata> ImportEntities(ImportEntitiesRequest request, CallSettings callSettings = null)

Imports entities into Google Cloud Datastore. Existing entities with the same key are overwritten. The import occurs in the background and its progress can be monitored and managed via the Operation resource that is created. If an ImportEntities operation is cancelled, it is possible that a subset of the data has already been imported to Cloud Datastore.

Parameters
Name	Description
`request`	`ImportEntitiesRequest` 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
`Google.LongRunning.Operation<Empty, ImportEntitiesMetadata>`	The RPC response.

Example

// Create client
DatastoreAdminClient datastoreAdminClient = DatastoreAdminClient.Create();
// Initialize request argument(s)
ImportEntitiesRequest request = new ImportEntitiesRequest
{
    ProjectId = "",
    Labels = { { "", "" }, },
    InputUrl = "",
    EntityFilter = new EntityFilter(),
};
// Make the request
Operation<Empty, ImportEntitiesMetadata> response = datastoreAdminClient.ImportEntities(request);

// Poll until the returned long-running operation is complete
Operation<Empty, ImportEntitiesMetadata> completedResponse = response.PollUntilCompleted();
// Retrieve the operation result
Empty result = completedResponse.Result;

// Or get the name of the operation
string operationName = response.Name;
// This name can be stored, then the long-running operation retrieved later by name
Operation<Empty, ImportEntitiesMetadata> retrievedResponse = datastoreAdminClient.PollOnceImportEntities(operationName);
// Check if the retrieved long-running operation has completed
if (retrievedResponse.IsCompleted)
{
    // If it has completed, then access the result
    Empty retrievedResult = retrievedResponse.Result;
}

ImportEntities(String, IDictionary<String, String>, String, EntityFilter, CallSettings)

public virtual Operation<Empty, ImportEntitiesMetadata> ImportEntities(string projectId, IDictionary<string, string> labels, string inputUrl, EntityFilter entityFilter, CallSettings callSettings = null)

Parameters
Name	Description
`projectId`	`String` Required. Project ID against which to make the request.
`labels`	`IDictionary<String, String>` Client-assigned labels.
`inputUrl`	`String` Required. The full resource URL of the external storage location. Currently, only Google Cloud Storage is supported.

For more information about Cloud Storage namespace paths, see Object name considerations. For more information, see [google.datastore.admin.v1.ExportEntitiesResponse.output_url][google.datastore.admin.v1.ExportEntitiesResponse.output_url].
`entityFilter`	`EntityFilter` Optionally specify which kinds/namespaces are to be imported. If provided, the list must be a subset of the EntityFilter used in creating the export, otherwise a FAILED_PRECONDITION error will be returned. If no filter is specified then all entities from the export are imported.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Returns
Type	Description
`Google.LongRunning.Operation<Empty, ImportEntitiesMetadata>`	The RPC response.

Example

// Create client
