Class DatastoreAdminGrpc.DatastoreAdminFutureStub (2.21.1)

public static final class DatastoreAdminGrpc.DatastoreAdminFutureStub extends AbstractFutureStub<DatastoreAdminGrpc.DatastoreAdminFutureStub>

A stub to allow clients to do ListenableFuture-style rpc calls to service DatastoreAdmin.

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.

protected DatastoreAdminGrpc.DatastoreAdminFutureStub build(Channel channel, CallOptions callOptions)

Parameters
Name	Description
`channel`	`io.grpc.Channel`
`callOptions`	`io.grpc.CallOptions`

Returns
Type	Description
`DatastoreAdminGrpc.DatastoreAdminFutureStub`

Overrides

io.grpc.stub.AbstractStub.build(io.grpc.Channel,io.grpc.CallOptions)

createIndex(CreateIndexRequest request)

public ListenableFuture<Operation> createIndex(CreateIndexRequest request)

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.

Parameter
Name	Description
`request`	`CreateIndexRequest`

Returns
Type	Description
`com.google.common.util.concurrent.ListenableFuture<Operation>`

deleteIndex(DeleteIndexRequest request)

public ListenableFuture<Operation> deleteIndex(DeleteIndexRequest request)

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.

Parameter
Name	Description
`request`	`DeleteIndexRequest`

Returns
Type	Description
`com.google.common.util.concurrent.ListenableFuture<Operation>`

exportEntities(ExportEntitiesRequest request)

public ListenableFuture<Operation> exportEntities(ExportEntitiesRequest request)

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.

Parameter
Name	Description
`request`	`ExportEntitiesRequest`

Returns
Type	Description
`com.google.common.util.concurrent.ListenableFuture<Operation>`

getIndex(GetIndexRequest request)

public ListenableFuture<Index> getIndex(GetIndexRequest request)

Gets an index.

Parameter
Name	Description
`request`	`GetIndexRequest`

Returns
Type	Description
`com.google.common.util.concurrent.ListenableFuture<Index>`

importEntities(ImportEntitiesRequest request)

public ListenableFuture<Operation> importEntities(ImportEntitiesRequest request)

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.

Parameter
Name	Description
`request`	`ImportEntitiesRequest`

Returns
Type	Description
`com.google.common.util.concurrent.ListenableFuture<Operation>`

listIndexes(ListIndexesRequest request)

public ListenableFuture<ListIndexesResponse> listIndexes(ListIndexesRequest request)

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.

Parameter
Name	Description
`request`	`ListIndexesRequest`

Returns
Type	Description
`com.google.common.util.concurrent.ListenableFuture<ListIndexesResponse>`
