Inheritance

builtins.object > DatabaseAdminAsyncClient

Properties

transport

Returns the transport used by the client instance.

Returns

Type	Description
DatabaseAdminTransport	The transport used by the client instance.

Methods

DatabaseAdminAsyncClient

DatabaseAdminAsyncClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Union[str, google.cloud.spanner_admin_database_v1.services.database_admin.transports.base.DatabaseAdminTransport] = 'grpc_asyncio', 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 database 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, `.DatabaseAdminTransport`] The transport to use. If set to None, a transport is chosen automatically.
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.

Exceptions

Type	Description
google.auth.exceptions.MutualTlsChannelError	If mutual TLS transport creation failed for any reason.

backup_path

backup_path(project: str, instance: str, backup: str)

Returns a fully-qualified backup string.

Description

google.iam.v1.policy_pb2.Policy

An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A Policy is a collection of bindings. A binding binds one or more members, or principals, to a single role. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions; each role can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a binding can also specify a condition, which is a logical expression that allows access to a resource only if the expression evaluates to true. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](\ https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" ],="" "etag":="" "bwwwja0yfja=", " version":="" 3="" }="" **yaml="" example:**="" bindings:="" -="" members:="" -="" user:\="" mike@example.com="" -="" group:\="" admins@example.com="" -="" domain:google.com="" -="" serviceaccount:\="" my-project-id@appspot.gserviceaccount.com="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:\="" eve@example.com="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time="">< timestamp('2020-10-01t00:00:00.000z')="" etag:="" bwwwja0yfja="version:" 3="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the="" [iam="" documentation](\="">

get_mtls_endpoint_and_cert_source

get_mtls_endpoint_and_cert_source(
    client_options: Optional[google.api_core.client_options.ClientOptions] = None,
)

Return the API endpoint and client cert source for mutual TLS.

The client cert source is determined in the following order: (1) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not "true", the client cert source is None. (2) if client_options.client_cert_source is provided, use the provided one; if the default client cert source exists, use the default one; otherwise the client cert source is None.

The API endpoint is determined in the following order: (1) if client_options.api_endpoint if provided, use the provided one. (2) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "always", use the default mTLS endpoint; if the environment variabel is "never", use the default API endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise use the default API endpoint.

Create a new database by restoring from a completed backup. The new database must be in the same project and in an instance with the same instance configuration as the instance containing the backup. The returned database [long-running operation][google.longrunning.Operation] has a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id>, and can be used to track the progress of the operation, and to cancel it. The metadata][google.longrunning.Operation.metadata] field type is RestoreDatabaseMetadata][google.spanner.admin.database.v1.RestoreDatabaseMetadata]. The response][google.longrunning.Operation.response] type is Database][google.spanner.admin.database.v1.Database], if successful. Cancelling the returned operation will stop the restore and delete the database. There can be only one database being restored into an instance at a time. Once the restore operation completes, a new restore operation can be initiated, without waiting for the optimize operation associated with the first restore to complete.

test_iam_permissions

test_iam_permissions(request: Optional[Union[google.iam.v1.iam_policy_pb2.TestIamPermissionsRequest, dict]] = None, *, resource: Optional[str] = None, permissions: Optional[Sequence[str]] = 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]] = ())

Returns permissions that the caller has on the specified database or backup resource.

Attempting this RPC on a non-existent Cloud Spanner database will result in a NOT_FOUND error if the user has spanner.databases.list permission on the containing Cloud Spanner instance. Otherwise returns an empty set of permissions. Calling this method on a backup that does not exist will result in a NOT_FOUND error if the user has spanner.backups.list permission on the containing instance.

Parameters

Name	Description
request	`Union[google.cloud.spanner_admin_database_v1.types.UpdateBackupRequest, dict]` The request object. The request for `UpdateBackup][google.spanner.admin.database.v1.DatabaseAdmin.UpdateBackup]`.
backup	`Backup` Required. The backup to update. `backup.name`, and the fields to be updated as specified by `update_mask` are required. Other fields are ignored. Update is only supported for the following fields: - `backup.expire_time`. This corresponds to the `backup` field on the `request` instance; if `request` is provided, this should not be set.
update_mask	`google.protobuf.field_mask_pb2.FieldMask` Required. A mask specifying which fields (e.g. `expire_time`) in the Backup resource should be updated. This mask is relative to the Backup resource, not to the request message. The field mask must always be specified; this prevents any future fields from being erased accidentally by clients that do not know about them. This corresponds to the `update_mask` field on the `request` instance; if `request` is provided, this should not be set.
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.cloud.spanner_admin_database_v1.types.Backup	A backup of a Cloud Spanner database.

update_database_ddl

update_database_ddl(request: Optional[Union[google.cloud.spanner_admin_database_v1.types.spanner_database_admin.UpdateDatabaseDdlRequest, dict]] = None, *, database: Optional[str] = None, statements: Optional[Sequence[str]] = 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]] = ())

Updates the schema of a Cloud Spanner database by creating/altering/dropping tables, columns, indexes, etc. The returned long-running operation][google.longrunning.Operation] will have a name of the format <database_name>/operations/<operation_id> and can be used to track execution of the schema change(s). The metadata][google.longrunning.Operation.metadata] field type is UpdateDatabaseDdlMetadata][google.spanner.admin.database.v1.UpdateDatabaseDdlMetadata]. The operation has no response.

    # Handle the response
    print(response)

Parameters

Name	Description
request	`Union[google.cloud.spanner_admin_database_v1.types.UpdateDatabaseDdlRequest, dict]` The request object. Enqueues the given DDL statements to be applied, in order but not necessarily all at once, to the database schema at some point (or points) in the future. The server checks that the statements are executable (syntactically valid, name tables that exist, etc.) before enqueueing them, but they may still fail upon later execution (e.g., if a statement from another batch of statements is applied first and it conflicts in some way, or if there is some data-related problem like a `NULL` value in a column to which `NOT NULL` would be added). If a statement fails, all subsequent statements in the batch are automatically cancelled. Each batch of statements is assigned a name which can be used with the `Operations][google.longrunning.Operations]` API to monitor progress. See the `operation_id][google.spanner.admin.database.v1.UpdateDatabaseDdlRequest.operation_id]` field for more details.
database	`str` Required. The database to update. This corresponds to the `database` field on the `request` instance; if `request` is provided, this should not be set.
statements	:class:`Sequence[str]` Required. DDL statements to be applied to the database. This corresponds to the `statements` field on the `request` instance; if `request` is provided, this should not be set.
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_async.AsyncOperation

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); }
