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.
