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.

Public Instance Methods

configure() { |config| ... } click to toggle source

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 {::Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin::Client::Configuration} for a description of the configuration fields.

@yield [config] Configure the Client client. @yieldparam config [Client::Configuration]

@return [Client::Configuration]

end
create_instance(request, options = nil) { |response, operation| ... } click to toggle source

Creates an instance and begins preparing it to begin serving. The returned {::Google::Longrunning::Operation 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 {::Google::Longrunning::Operation 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 {::Google::Longrunning::Operation#metadata metadata} field type is {::Google::Cloud::Spanner::Admin::Instance::V1::CreateInstanceMetadata CreateInstanceMetadata}. The {::Google::Longrunning::Operation#response response} field type is {::Google::Cloud::Spanner::Admin::Instance::V1::Instance Instance}, if successful.

Deletes an instance.

Immediately upon completion of the request:

  irrevocably disappear from the API. All data in the databases
  is permanently deleted.

update_instance(request, options = nil) { |response, operation| ... } click to toggle source

Updates an instance, and begins allocating or releasing resources as requested. The returned [long-running 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
  {::Google::Cloud::Spanner::Admin::Instance::V1::UpdateInstanceMetadata#cancel_time 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 {::Google::Longrunning::Operation 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 {::Google::Longrunning::Operation#metadata metadata} field type is {::Google::Cloud::Spanner::Admin::Instance::V1::UpdateInstanceMetadata UpdateInstanceMetadata}. The {::Google::Longrunning::Operation#response response} field type is {::Google::Cloud::Spanner::Admin::Instance::V1::Instance Instance}, if successful.

Authorization requires `spanner.instances.update` permission on resource {::Google::Cloud::Spanner::Admin::Instance::V1::Instance#name name}.

@overload update_instance(request, options = nil)

Pass arguments to `update_instance` via a request object, either of type

@param request [::Google::Cloud::Spanner::Admin::Instance::V1::UpdateInstanceRequest, ::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.
@param options [::Gapic::CallOptions, ::Hash]
  Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

@overload update_instance(instance: nil, field_mask: nil)

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).

@param instance [::Google::Cloud::Spanner::Admin::Instance::V1::Instance, ::Hash]
  Required. The instance to update, which must always include the instance
  name.  Otherwise, only fields mentioned in {::Google::Cloud::Spanner::Admin::Instance::V1::UpdateInstanceRequest#field_mask field_mask} need be included.
@param field_mask [::Google::Protobuf::FieldMask, ::Hash]
  Required. A mask specifying which fields in {::Google::Cloud::Spanner::Admin::Instance::V1::Instance Instance} should be updated.
  The field mask must always be specified; this prevents any future fields in
  {::Google::Cloud::Spanner::Admin::Instance::V1::Instance Instance} from being erased accidentally by clients that do not know
  about them.
