class google.cloud.spanner_admin_database_v1.services.database_admin.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>)[source]

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

Instantiates the database admin client.

Parameters
  • 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.

Raises

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

A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource.

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’)”, } }

]

}

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’)

For a description of IAM and its features, see the [IAM developer’s guide](https://cloud.google.com/iam/docs).

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.

Parameters
  • request (Union[google.cloud.spanner_admin_database_v1.types.RestoreDatabaseRequest, dict]) – The request object. The request for [RestoreDatabase][google.spanner.admin.database.v1.DatabaseAdmin.RestoreDatabase].

    This corresponds to the parent field on the request instance; if request is provided, this should not be set.

  • database_id (str) –

    Required. The id of the database to create and restore to. This database must not already exist. The database_id appended to parent forms the full database name of the form projects/<project>/instances/<instance>/databases/<database_id>.

    This corresponds to the database_id field on the request instance; if request is provided, this should not be set.

  • backup (str) –

    Name of the backup from which to restore. Values are of the form projects/<project>/instances/<instance>/backups/<backup>.

    This corresponds to the backup field on the request instance; if request is provided, this should not be set.

  • timeout (float) – The timeout for this request.

  • metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns

Defines an Identity and Access Management (IAM) policy. It is used to

specify access control policies for Cloud Platform resources.

A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource.

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’)”, } }

]

}

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’)

async 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, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ()) google.api_core.operation_async.AsyncOperation[source]

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.

Parameters
  • 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 (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

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 {}.

Return type

google.api_core.operation_async.AsyncOperation

class google.cloud.spanner_admin_database_v1.services.database_admin.DatabaseAdminClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.spanner_admin_database_v1.services.database_admin.transports.base.DatabaseAdminTransport]] = 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>)[source]

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

Instantiates the database admin client.

Parameters
  • 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 (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.

Raises

google.auth.exceptions.MutualTLSChannelError – If mutual TLS transport creation failed for any reason.

__exit__(type, value, traceback)[source]

Releases underlying transport’s resources.

Warning

ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

Updates a pending or completed [Backup][google.spanner.admin.database.v1.Backup].

Parameters
  • 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 (google.cloud.spanner_admin_database_v1.types.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.

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, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ()) google.api_core.operation.Operation[source]

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.

Parameters
  • 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 (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

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 {}.

Return type

google.api_core.operation.Operation

This class thinly wraps an initial google.cloud.spanner_admin_database_v1.types.ListBackupOperationsResponse object, and provides an __aiter__ method to iterate through its operations field.

If there are more pages, the __aiter__ method will make additional ListBackupOperations requests and continue to iterate through the operations field on the corresponding responses.

All the usual google.cloud.spanner_admin_database_v1.types.ListBackupOperationsResponse attributes are available on the pager. If multiple requests are made, only the most recent response is retained, and thus used for attribute lookup.

Instantiates the pager.
