Class InstanceAdminAsyncClient (3.17.0)

InstanceAdminAsyncClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Union[str, google.cloud.spanner_admin_instance_v1.services.instance_admin.transports.base.InstanceAdminTransport] = '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>)

Cloud Spanner Instance Admin API The Cloud Spanner Instance Admin API can be used to create, delete, modify and list instances. Instances are dedicated Cloud Spanner serving and storage resources to be used by Cloud Spanner databases. Each instance has a "configuration", which dictates where the serving resources for the Cloud Spanner instance are located (e.g., US-central, Europe). Configurations are created by Google based on resource availability.

Cloud Spanner billing is based on the instances that exist and their sizes. After an instance exists, there are no additional per-database or per-operation charges for use of the instance (though there may be additional network bandwidth charges). Instances offer isolation: problems with databases in one instance will not affect other instances. However, within an instance databases can affect each other. For example, if one database in an instance receives a lot of requests and consumes most of the instance resources, fewer resources are available for other databases in that instance, and their performance may suffer.

Properties

transport

Returns the transport used by the client instance.

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

Methods

InstanceAdminAsyncClient

InstanceAdminAsyncClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Union[str, google.cloud.spanner_admin_instance_v1.services.instance_admin.transports.base.InstanceAdminTransport] = '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 instance 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, .InstanceAdminTransport]` 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.

Creates an instance and begins preparing it to begin serving. The returned [long-running operation][google.longrunning.Operation] can be used to track the progress of preparing the new instance. The instance name is assigned by the caller. If the named instance already exists, CreateInstance returns ALREADY_EXISTS.

Immediately upon completion of this request:

The instance is readable via the API, with all requested attributes but no allocated resources. Its state is CREATING.

Until completion of the returned operation:

Cancelling the operation renders the instance immediately unreadable via the API.
The instance can be deleted.
All other attempts to modify the instance are rejected.

Upon completion of the returned operation:

Billing for all successfully-allocated resources begins (some types may have lower than the requested levels).
Databases can be created in the instance.
The instance's allocated resource levels are readable via the API.
The instance's state becomes READY.

The returned [long-running operation][google.longrunning.Operation] will have a name of the format <instance_name>/operations/<operation_id> and can be used to track creation of the instance. The metadata][google.longrunning.Operation.metadata] field type is CreateInstanceMetadata][google.spanner.admin.instance.v1.CreateInstanceMetadata]. The response][google.longrunning.Operation.response] field type is Instance][google.spanner.admin.instance.v1.Instance], if successful.

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:** { "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](\="">

`request`	`Union[google.iam.v1.iam_policy_pb2.TestIamPermissionsRequest, dict]` The request object. Request message for `TestIamPermissions` method.
`resource`	`str` REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field. This corresponds to the `resource` field on the `request` instance; if `request` is provided, this should not be set.
`permissions`	`:class:Sequence[str]` The set of permissions to check for the `resource`. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see `IAM Overview https://cloud.google.com/iam/docs/overview#permissions`__. This corresponds to the `permissions` 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.iam.v1.iam_policy_pb2.TestIamPermissionsResponse`	Response message for TestIamPermissions method.

update_instance

update_instance(request: Optional[Union[google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.UpdateInstanceRequest, dict]] = None, *, instance: Optional[google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.Instance] = None, field_mask: Optional[google.protobuf.field_mask_pb2.FieldMask] = 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 an instance, and begins allocating or releasing resources as requested. The returned [long-running operation][google.longrunning.Operation] can be used to track the progress of updating the instance. If the named instance does not exist, returns NOT_FOUND.

Immediately upon completion of this request:

For resource types for which a decrease in the instance's allocation has been requested, billing is based on the newly-requested level.

Until completion of the returned operation:

Cancelling the operation sets its metadata's cancel_time][google.spanner.admin.instance.v1.UpdateInstanceMetadata.cancel_time], and begins restoring resources to their pre-request values. The operation is guaranteed to succeed at undoing all resource changes, after which point it terminates with a CANCELLED status.
All other attempts to modify the instance are rejected.
Reading the instance via the API continues to give the pre-request resource levels.

Upon completion of the returned operation:

Billing begins for all successfully-allocated resources (some types may have lower than the requested levels).
All newly-reserved resources are available for serving the instance's tables.
The instance's new resource levels are readable via the API.

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

Authorization requires spanner.instances.update permission on the resource name][google.spanner.admin.instance.v1.Instance.name].

Parameters
Name	Description
`request`	`Union[google.cloud.spanner_admin_instance_v1.types.UpdateInstanceRequest, dict]` The request object. The request for `UpdateInstance][google.spanner.admin.instance.v1.InstanceAdmin.UpdateInstance]`.
`instance`	`Instance` Required. The instance to update, which must always include the instance name. Otherwise, only fields mentioned in `field_mask][google.spanner.admin.instance.v1.UpdateInstanceRequest.field_mask]` need be included. This corresponds to the `instance` field on the `request` instance; if `request` is provided, this should not be set.
`field_mask`	`google.protobuf.field_mask_pb2.FieldMask` Required. A mask specifying which fields in `Instance][google.spanner.admin.instance.v1.Instance]` should be updated. The field mask must always be specified; this prevents any future fields in `Instance][google.spanner.admin.instance.v1.Instance]` from being erased accidentally by clients that do not know about them. This corresponds to the `field_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.api_core.operation_async.AsyncOperation`	An object representing a long-running operation. The result type for the operation will be Instance An isolated set of Cloud Spanner resources on which databases can be hosted.
