Class DatastoreAdminClient (2.5.1)

DatastoreAdminClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.datastore_admin_v1.services.datastore_admin.transports.base.DatastoreAdminTransport]] = None, client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

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.

Properties

transport

Returns the transport used by the client instance.

Returns
Type	Description
`DatastoreAdminTransport`	The transport used by the client instance.

Methods

DatastoreAdminClient

DatastoreAdminClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.datastore_admin_v1.services.datastore_admin.transports.base.DatastoreAdminTransport]] = None, client_options: Optional[google.api_core.client_options.ClientOptions] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the datastore admin client.

Parameters
Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, DatastoreAdminTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`google.api_core.client_options.ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.
`client_info`	`google.api_core.gapic_v1.client_info.ClientInfo` The client info used to send a user-agent string along with API requests. If `None`, then default info will be used. Generally, you only need to set this if you're developing your own client library.

Exceptions
Type	Description
`google.auth.exceptions.MutualTLSChannelError`	If mutual TLS transport creation failed for any reason.

exit

__exit__(type, value, traceback)

Releases underlying transport's resources.

common_billing_account_path

common_billing_account_path(billing_account: str)

Returns a fully-qualified billing_account string.

common_folder_path

common_folder_path(folder: str)

Returns a fully-qualified folder string.

common_location_path

common_location_path(project: str, location: str)

Returns a fully-qualified location string.

common_organization_path

common_organization_path(organization: str)

Returns a fully-qualified organization string.

common_project_path

common_project_path(project: str)

Returns a fully-qualified project string.

create_index

create_index(request: Optional[Union[google.cloud.datastore_admin_v1.types.datastore_admin.CreateIndexRequest, dict]] = None, *, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

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.

from google.cloud import datastore_admin_v1

def sample_create_index():
    # Create a client
    client = datastore_admin_v1.DatastoreAdminClient()

    # Initialize request argument(s)
    request = datastore_admin_v1.CreateIndexRequest(
    )

    # Make the request
    operation = client.create_index(request=request)

    print("Waiting for operation to complete...")

    response = operation.result()

    # Handle the response
    print(response)

Parameters
Name	Description
`request`	`Union[google.cloud.datastore_admin_v1.types.CreateIndexRequest, dict]` The request object. The request for `google.datastore.admin.v1.DatastoreAdmin.CreateIndex][google.datastore.admin.v1.DatastoreAdmin.CreateIndex]`.
`retry`	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
`timeout`	`float` The timeout for this request.
`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns
Type	Description
`google.api_core.operation.Operation`	An object representing a long-running operation. The result type for the operation will be Index Datastore composite index definition.

delete_index

delete_index(request: Optional[Union[google.cloud.datastore_admin_v1.types.datastore_admin.DeleteIndexRequest, dict]] = None, *, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

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.

def sample_export_entities():
    # Create a client
    client = datastore_admin_v1.DatastoreAdminClient()

    # Initialize request argument(s)
    request = datastore_admin_v1.ExportEntitiesRequest(
        project_id="project_id_value",
        output_url_prefix="output_url_prefix_value",
    )

    operation = client.export_entities(request=request)

    print("Waiting for operation to complete...")

    response = operation.result()

    # Handle the response
    print(response)

from google.cloud import datastore_admin_v1

def sample_import_entities():
    # Create a client
    client = datastore_admin_v1.DatastoreAdminClient()

    # Initialize request argument(s)
    request = datastore_admin_v1.ImportEntitiesRequest(
        project_id="project_id_value",
        input_url="input_url_value",

    # Make the request
    operation = client.import_entities(request=request)

    print("Waiting for operation to complete...")

    response = operation.result()

    # Handle the response
    print(response)

Parameters
Name	Description
`request`	`Union[google.cloud.datastore_admin_v1.types.ImportEntitiesRequest, dict]` The request object. The request for `google.datastore.admin.v1.DatastoreAdmin.ImportEntities][google.datastore.admin.v1.DatastoreAdmin.ImportEntities]`.
`project_id`	`str` Required. Project ID against which to make the request. This corresponds to the `project_id` field on the `request` instance; if `request` is provided, this should not be set.
`labels`	`Dict[str, str]` Client-assigned labels. This corresponds to the `labels` field on the `request` instance; if `request` is provided, this should not be set.
`input_url`	`str` Required. The full resource URL of the external storage location. Currently, only Google Cloud Storage is supported. So input_url should be of the form: `gs://BUCKET_NAME[/NAMESPACE_PATH]/OVERALL_EXPORT_METADATA_FILE`, where `BUCKET_NAME` is the name of the Cloud Storage bucket, `NAMESPACE_PATH` is an optional Cloud Storage namespace path (this is not a Cloud Datastore namespace), and `OVERALL_EXPORT_METADATA_FILE` is the metadata file written by the ExportEntities operation. For more information about Cloud Storage namespace paths, see `Object name considerations https://cloud.google.com/storage/docs/naming#object-considerations`__. For more information, see `google.datastore.admin.v1.ExportEntitiesResponse.output_url][google.datastore.admin.v1.ExportEntitiesResponse.output_url]`. This corresponds to the `input_url` field on the `request` instance; if `request` is provided, this should not be set.
`entity_filter`	`google.cloud.datastore_admin_v1.types.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. This corresponds to the `entity_filter` field on the `request` instance; if `request` is provided, this should not be set.

Returns

Type Description

google.api_core.operation.Operation An object representing a long-running operation. The result type for the operation will be google.protobuf.empty_pb2.Empty A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); } The JSON representation for Empty is empty JSON object {}.

list_indexes

list_indexes(request: Optional[Union[google.cloud.datastore_admin_v1.types.datastore_admin.ListIndexesRequest, dict]] = None, *, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

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.
