class google.cloud.spanner_admin_instance_v1.services.instance_admin.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>)[source]

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.

Instantiates the instance 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, 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.

Raises

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

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

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 resource [name][google.spanner.admin.instance.v1.Instance.name].

Parameters
  • 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 (google.cloud.spanner_admin_instance_v1.types.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.

Returns

An object representing a long-running operation.

The result type for the operation will be google.cloud.spanner_admin_instance_v1.types.Instance An isolated set of Cloud Spanner resources on which databases can be hosted.

Return type

google.api_core.operation_async.AsyncOperation

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

Instantiates the instance 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, InstanceAdminTransport]) – 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 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 resource [name][google.spanner.admin.instance.v1.Instance.name].

Parameters
  • 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 (google.cloud.spanner_admin_instance_v1.types.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

An object representing a long-running operation.

The result type for the operation will be google.cloud.spanner_admin_instance_v1.types.Instance An isolated set of Cloud Spanner resources on which databases can be hosted.

Return type

google.api_core.operation.Operation

class google.cloud.spanner_admin_instance_v1.services.instance_admin.pagers.ListInstanceConfigsAsyncPager(method: Callable[[...], Awaitable[google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.ListInstanceConfigsResponse]], request: google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.ListInstanceConfigsRequest, response: google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.ListInstanceConfigsResponse, *, metadata: Sequence[Tuple[str, str]] = ())[source]

A pager for iterating through list_instance_configs requests.

This class thinly wraps an initial google.cloud.spanner_admin_instance_v1.types.ListInstanceConfigsResponse object, and provides an __aiter__ method to iterate through its instance_configs field.

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

All the usual google.cloud.spanner_admin_instance_v1.types.ListInstanceConfigsResponse 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.

Parameters
class google.cloud.spanner_admin_instance_v1.services.instance_admin.pagers.ListInstanceConfigsPager(method: Callable[[...], google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.ListInstanceConfigsResponse], request: google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.ListInstanceConfigsRequest, response: google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.ListInstanceConfigsResponse, *, metadata: Sequence[Tuple[str, str]] = ())[source]
