Cloud Spanner Instance Admin V1 API - Class Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin::Client (v0.7.0)

Reference documentation and code samples for the Cloud Spanner Instance Admin V1 API class Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin::Client.

Client for the InstanceAdmin service.

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.

Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the InstanceAdmin Client class.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Example
# Modify the configuration for all InstanceAdmin clients
::Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the InstanceAdmin Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter

#create_instance

def create_instance(request, options = nil) -> ::Gapic::Operation
def create_instance(parent: nil, instance_id: nil, instance: nil) -> ::Gapic::Operation

Creates an instance and begins preparing it to begin serving. The returned long-running 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 will have a name of the format <instance_name>/operations/<operation_id> and can be used to track creation of the instance. The metadata field type is CreateInstanceMetadata. The response field type is Instance, if successful.

Overloads
def create_instance(request, options = nil) -> ::Gapic::Operation
Pass arguments to create_instance via a request object, either of type CreateInstanceRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Spanner::Admin::Instance::V1::CreateInstanceRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.
def create_instance(parent: nil, instance_id: nil, instance: nil) -> ::Gapic::Operation
Pass arguments to create_instance via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) — Required. The name of the project in which to create the instance. Values are of the form projects/<project>.
  • instance_id (::String) — Required. The ID of the instance to create. Valid identifiers are of the form [a-z][-a-z0-9]*[a-z0-9] and must be between 2 and 64 characters in length.
  • instance (::Google::Cloud::Spanner::Admin::Instance::V1::Instance, ::Hash) — Required. The instance to create. The name may be omitted, but if specified must be <parent>/instances/<instance_id>.
Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the RPC is aborted.

#update_instance

def update_instance(request, options = nil) -> ::Gapic::Operation
def update_instance(instance: nil, field_mask: nil) -> ::Gapic::Operation

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, 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 will have a name of the format <instance_name>/operations/<operation_id> and can be used to track the instance modification. The metadata field type is UpdateInstanceMetadata. The response field type is Instance, if successful.

Authorization requires spanner.instances.update permission on the resource name.

Overloads

def update_instance(instance: nil, field_mask: nil) -> ::Gapic::Operation
Pass arguments to update_instance via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
