Enclosing class:
DatastoreAdminGrpc
public static final class DatastoreAdminGrpc.DatastoreAdminBlockingStub extends io.grpc.stub.AbstractBlockingStub<DatastoreAdminGrpc.DatastoreAdminBlockingStub>
A stub to allow clients to do synchronous 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.

  • Method Details

    • build

      protected DatastoreAdminGrpc.DatastoreAdminBlockingStub build(io.grpc.Channel channel, io.grpc.CallOptions callOptions)
      Specified by:
      build in class io.grpc.stub.AbstractStub<DatastoreAdminGrpc.DatastoreAdminBlockingStub>

    • exportEntities

      public com.google.longrunning.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.

    • importEntities

      public com.google.longrunning.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.

    • createIndex

      public com.google.longrunning.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][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.

    • deleteIndex

      public com.google.longrunning.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][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.

    • getIndex

      public Index getIndex(GetIndexRequest request)
       Gets an index.

    • listIndexes

      public 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.
