Remarks

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.

Constructors

InstanceAdminClientImpl(InstanceAdmin.InstanceAdminClient, InstanceAdminSettings, ILogger)

public InstanceAdminClientImpl(InstanceAdmin.InstanceAdminClient grpcClient, InstanceAdminSettings settings, ILogger logger)

Constructs a client wrapper for the InstanceAdmin service, with the specified gRPC client and settings.

Parameters
Name	Description
grpcClient	InstanceAdmin.InstanceAdminClient The underlying gRPC client.
settings	InstanceAdminSettings The base InstanceAdminSettings used within this client.
logger	ILogger Optional ILogger to use within this client.

Fields

ResourcePrefixHeader

public const string ResourcePrefixHeader = "google-cloud-resource-prefix"

The name of the header used for efficiently routing requests.

Field Value
Type	Description
String

Remarks

This should be set to the instance resource name ("projects/{projectId}/instances/{instanceId}") for some RPCs and to the project resource name for others ("projects/{projectId}"). For non-streaming calls, InstanceAdminClientImpl performs this automatically. This cannot be performed automatically for streaming calls due to the separation between initializing the stream and sending requests, so client code should set the value in a CallSettings. Typically this is performed with either the FromHeader(string, string) factory method or the WithHeader(CallSettings, string, string) extension method.

Methods

CreateInstance(CreateInstanceRequest, CallSettings)

public override Operation<Instance, CreateInstanceMetadata> CreateInstance(CreateInstanceRequest request, CallSettings callSettings = null)

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.

UpdateInstance(UpdateInstanceRequest, CallSettings)

public override Operation<Instance, UpdateInstanceMetadata> UpdateInstance(UpdateInstanceRequest request, CallSettings callSettings = null)

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].
