Cloud Spanner Database Admin API

The Cloud Spanner Database Admin API can be used to:

create, drop, and list databases
update the schema of pre-existing databases
create, delete and list backups for a database
restore a database from an existing backup

Properties

api_endpoint

Return the API endpoint used by the client instance.

Returns
Type	Description
`str`	The API endpoint used by the client instance.

transport

Returns the transport used by the client instance.

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

universe_domain

Return the universe domain used by the client instance.

Returns
Type	Description
`str`	The universe domain used by the client instance.

Methods

DatabaseAdminAsyncClient

DatabaseAdminAsyncClient(*, credentials: typing.Optional[google.auth.credentials.Credentials] = None, transport: typing.Optional[typing.Union[str, google.cloud.spanner_admin_database_v1.services.database_admin.transports.base.DatabaseAdminTransport, typing.Callable[[...], google.cloud.spanner_admin_database_v1.services.database_admin.transports.base.DatabaseAdminTransport]]] = 'grpc_asyncio', client_options: typing.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 async 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`	`Optional[Union[str,DatabaseAdminTransport,Callable[..., DatabaseAdminTransport]]]` The transport to use, or a Callable that constructs and returns a new transport to use. If a Callable is given, it will be called with the same set of initialization arguments as used in the DatabaseAdminTransport constructor. If set to None, a transport is chosen automatically.
`client_options`	`Optional[Union[google.api_core.client_options.ClientOptions, dict]]` Custom options for the client. 1. The `api_endpoint` property can be used to override the default endpoint provided by the client when `transport` is not explicitly provided. Only if this property is not set and `transport` was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: "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). 2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide a client certificate for mTLS 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. 3. The `universe_domain` property can be used to override the default "googleapis.com" universe. Note that `api_endpoint` property still takes precedence; and `universe_domain` is currently not supported for mTLS.
`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.

backup_path

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

Returns a fully-qualified backup string.

Type 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:** :literal:\ { "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:** :literal:\ 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:">\ \ For a description of IAM and its features, see the [IAM documentation](\ https://cloud.google.com/iam/docs/).

) -> google.api_core.operation_async.AsyncOperation

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.

    timeout: typing.Union[float, object] = _MethodDefault._DEFAULT_VALUE,
    metadata: typing.Sequence[typing.Tuple[str, str]] = ()
) -> google.api_core.operation_async.AsyncOperation

Updates a Cloud Spanner database. The returned [long-running operation][google.longrunning.Operation] can be used to track the progress of updating the database. If the named database does not exist, returns NOT_FOUND.

While the operation is pending:

The database's reconciling][google.spanner.admin.database.v1.Database.reconciling] field is set to true.
Cancelling the operation is best-effort. If the cancellation succeeds, the operation metadata's cancel_time][google.spanner.admin.database.v1.UpdateDatabaseMetadata.cancel_time] is set, the updates are reverted, and the operation terminates with a CANCELLED status.
New UpdateDatabase requests will return a FAILED_PRECONDITION error until the pending operation is done (returns successfully or with error).
Reading the database via the API continues to give the pre-request values.

Upon completion of the returned operation:

The new values are in effect and readable via the API.
The database's reconciling][google.spanner.admin.database.v1.Database.reconciling] field becomes false.

The returned [long-running operation][google.longrunning.Operation] will have a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id> and can be used to track the database modification. The metadata][google.longrunning.Operation.metadata] field type is UpdateDatabaseMetadata][google.spanner.admin.database.v1.UpdateDatabaseMetadata]. The response][google.longrunning.Operation.response] field type is Database][google.spanner.admin.database.v1.Database], if successful.

Parameters
Name	Description
`request`	`Optional[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:MutableSequence[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_async.AsyncRetry` 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); }
