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 async 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 (Optional[Union[str,InstanceAdminTransport,Callable[..., InstanceAdminTransport]]]) – 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 InstanceAdminTransport 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.

Raises

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

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

Returns

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`

Moves an instance to the target instance configuration. You can use the returned [long-running operation][google.longrunning.Operation] to track the progress of moving the instance.

MoveInstance returns FAILED_PRECONDITION if the instance meets any of the following criteria:

Is undergoing a move to a different instance configuration
Has backups
Has an ongoing update
Contains any CMEK-enabled databases
Is a free trial instance

While the operation is pending:

All other attempts to modify the instance, including changes to its compute capacity, are rejected.
The following database and backup admin operations are rejected:
- DatabaseAdmin.CreateDatabase
- DatabaseAdmin.UpdateDatabaseDdl (disabled if default_leader is specified in the request.)
- DatabaseAdmin.RestoreDatabase
- DatabaseAdmin.CreateBackup
- DatabaseAdmin.CopyBackup
Both the source and target instance configurations are subject to hourly compute and storage charges.
The instance might experience higher read-write latencies and a higher transaction abort rate. However, moving an instance doesn’t cause any downtime.

The returned [long-running operation][google.longrunning.Operation] has a name of the format <instance_name>/operations/<operation_id> and can be used to track the move instance operation. The [metadata][google.longrunning.Operation.metadata] field type is [MoveInstanceMetadata][google.spanner.admin.instance.v1.MoveInstanceMetadata]. The [response][google.longrunning.Operation.response] field type is [Instance][google.spanner.admin.instance.v1.Instance], if successful. Cancelling the operation sets its metadata’s [cancel_time][google.spanner.admin.instance.v1.MoveInstanceMetadata.cancel_time]. Cancellation is not immediate because it involves moving any data previously moved to the target instance configuration back to the original instance configuration. You can use this operation to track the progress of the cancellation. Upon successful completion of the cancellation, the operation terminates with CANCELLED status.

If not cancelled, upon completion of the returned operation:

The instance successfully moves to the target instance configuration.
You are billed for compute and storage in target instance configuration.

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

Parameters

request (Optional[Union[google.iam.v1.iam_policy_pb2.SetIamPolicyRequest, dict]]) – The request object. Request message for SetIamPolicy method.
resource (str) –
REQUIRED: The resource for which the policy is being specified. 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.
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

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`

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].

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 (Optional[Union[str,InstanceAdminTransport,Callable[..., InstanceAdminTransport]]]) – The transport to use, or a Callable that constructs and returns a new transport. If a Callable is given, it will be called with the same set of initialization arguments as used in the InstanceAdminTransport 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 the 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.

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!

property api_endpoint¶

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

Returns

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`

Moves an instance to the target instance configuration. You can use the returned [long-running operation][google.longrunning.Operation] to track the progress of moving the instance.

MoveInstance returns FAILED_PRECONDITION if the instance meets any of the following criteria:

Is undergoing a move to a different instance configuration
Has backups
Has an ongoing update
Contains any CMEK-enabled databases
Is a free trial instance

While the operation is pending:

All other attempts to modify the instance, including changes to its compute capacity, are rejected.
The following database and backup admin operations are rejected:
- DatabaseAdmin.CreateDatabase
- DatabaseAdmin.UpdateDatabaseDdl (disabled if default_leader is specified in the request.)
- DatabaseAdmin.RestoreDatabase
- DatabaseAdmin.CreateBackup
- DatabaseAdmin.CopyBackup
Both the source and target instance configurations are subject to hourly compute and storage charges.
The instance might experience higher read-write latencies and a higher transaction abort rate. However, moving an instance doesn’t cause any downtime.

The returned [long-running operation][google.longrunning.Operation] has a name of the format <instance_name>/operations/<operation_id> and can be used to track the move instance operation. The [metadata][google.longrunning.Operation.metadata] field type is [MoveInstanceMetadata][google.spanner.admin.instance.v1.MoveInstanceMetadata]. The [response][google.longrunning.Operation.response] field type is [Instance][google.spanner.admin.instance.v1.Instance], if successful. Cancelling the operation sets its metadata’s [cancel_time][google.spanner.admin.instance.v1.MoveInstanceMetadata.cancel_time]. Cancellation is not immediate because it involves moving any data previously moved to the target instance configuration back to the original instance configuration. You can use this operation to track the progress of the cancellation. Upon successful completion of the cancellation, the operation terminates with CANCELLED status.

If not cancelled, upon completion of the returned operation:

The instance successfully moves to the target instance configuration.
You are billed for compute and storage in target instance configuration.

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

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 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).

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].

While the operation is pending:

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

Upon completion of the returned operation:

Creating instances using the instance configuration uses the new values.
The new values of the instance configuration are readable via the API.
The instance configuration’s [reconciling][google.spanner.admin.instance.v1.InstanceConfig.reconciling] field becomes false.

A pager for iterating through list_instance_partition_operations requests.

This class thinly wraps an initial google.cloud.spanner_admin_instance_v1.types.ListInstancePartitionOperationsResponse object, and provides an __iter__ method to iterate through its operations field.

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

All the usual google.cloud.spanner_admin_instance_v1.types.ListInstancePartitionOperationsResponse attributes are available on the pager. If multiple requests are made, only the most recent response is retained, and thus used for attribute lookup.

Instantiate the pager.

Parameters

method (Callable) – The method that was originally called, and which instantiated this pager.
request (google.cloud.spanner_admin_instance_v1.types.ListInstancePartitionOperationsRequest) – The initial request object.
response (google.cloud.spanner_admin_instance_v1.types.ListInstancePartitionOperationsResponse) – The initial response object.
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.
