Cloud Spanner Instance Admin V1 API - Class Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin::Rest::Client (v0.11.0)

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

REST 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
Returns
Example 
# Modify the configuration for all InstanceAdmin clients
::Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin::Rest::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
Returns

#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
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.
Example

Basic example

require "google/cloud/spanner/admin/instance/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Spanner::Admin::Instance::V1::InstanceAdmin::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Spanner::Admin::Instance::V1::CreateInstanceRequest.new

# Call the create_instance method.
result = client.create_instance request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

#create_instance_config

def create_instance_config(request, options = nil) -> ::Gapic::Operation
def create_instance_config(parent: nil, instance_config_id: nil, instance_config: nil, validate_only: nil) -> ::Gapic::Operation

Creates an instance config and begins preparing it to be used. The returned long-running operation can be used to track the progress of preparing the new instance config. The instance config name is assigned by the caller. If the named instance config already exists, CreateInstanceConfig returns ALREADY_EXISTS.

Immediately after the request returns:

  • The instance config is readable via the API, with all requested attributes. The instance config's reconciling field is set to true. Its state is CREATING.

While the operation is pending:

  • Cancelling the operation renders the instance config immediately unreadable via the API.
  • Except for deleting the creating resource, all other attempts to modify the instance config are rejected.

Upon completion of the returned operation:

  • Instances can be created using the instance configuration.
  • The instance config's reconciling field becomes false. Its state becomes READY.

The returned long-running operation will have a name of the format <instance_config_name>/operations/<operation_id> and can be used to track creation of the instance config. The metadata field type is CreateInstanceConfigMetadata. The response field type is InstanceConfig, if successful.

Authorization requires spanner.instanceConfigs.create permission on the resource parent.

#list_instance_config_operations

def list_instance_config_operations(request, options = nil) -> ::Gapic::Operation
def list_instance_config_operations(parent: nil, filter: nil, page_size: nil, page_token: nil) -> ::Gapic::Operation

Lists the user-managed instance config [long-running operations][google.longrunning.Operation] in the given project. An instance config operation has a name of the form projects/<project>/instanceConfigs/<instance_config>/operations/<operation>. The long-running operation metadata field type metadata.type_url describes the type of the metadata. Operations returned include those that have completed/failed/canceled within the last 7 days, and pending operations. Operations returned are ordered by operation.metadata.value.start_time in descending order starting from the most recently started operation.

Overloads 
def list_instance_config_operations(request, options = nil) -> ::Gapic::Operation
Pass arguments to list_instance_config_operations via a request object, either of type ListInstanceConfigOperationsRequest or an equivalent Hash.
Parameters 
def list_instance_config_operations(parent: nil, filter: nil, page_size: nil, page_token: nil) -> ::Gapic::Operation
Pass arguments to list_instance_config_operations 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 project of the instance config operations. Values are of the form projects/<project>.
  • filter (::String) —

    An expression that filters the list of returned operations.

    A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: <, >, <=, >=, !=, =, or :. Colon : is the contains operator. Filter rules are not case sensitive.

    The following fields in the Operation are eligible for filtering:

    • name - The name of the long-running operation
    • done - False if the operation is in progress, else true.
    • metadata.@type - the type of metadata. For example, the type string for CreateInstanceConfigMetadata is type.googleapis.com/google.spanner.admin.instance.v1.CreateInstanceConfigMetadata.
    • metadata.<field_name> - any field in metadata.value. metadata.@type must be specified first, if filtering on metadata fields.
    • error - Error associated with the long-running operation.
    • response.@type - the type of response.
    • response.<field_name> - any field in response.value.

    You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic. However, you can specify AND, OR, and NOT logic explicitly.

    Here are a few examples:

    • done:true - The operation is complete.
    • (metadata.@type= \ type.googleapis.com/google.spanner.admin.instance.v1.CreateInstanceConfigMetadata) AND \ (metadata.instance_config.name:custom-config) AND \ (metadata.progress.start_time < \"2021-03-28T14:50:00Z\") AND \ (error:*) - Return operations where:
      • The operation's metadata type is CreateInstanceConfigMetadata.
      • The instance config name contains "custom-config".
      • The operation started before 2021-03-28T14:50:00Z.
      • The operation resulted in an error.
  • page_size (::Integer) — Number of operations to be returned in the response. If 0 or less, defaults to the server's maximum allowed page size.
  • page_token (::String) — If non-empty, page_token should contain a next_page_token from a previous ListInstanceConfigOperationsResponse to the same parent and with the same filter.
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.

  • request (::Google::Cloud::Spanner::Admin::Instance::V1::ListInstancesRequest, ::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 list_instances(parent: nil, page_size: nil, page_token: nil, filter: nil) -> ::Gapic::Rest::PagedEnumerable<::Google::Cloud::Spanner::Admin::Instance::V1::Instance>
Pass arguments to list_instances 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 for which a list of instances is requested. Values are of the form projects/<project>.
  • page_size (::Integer) — Number of instances to be returned in the response. If 0 or less, defaults to the server's maximum allowed page size.
  • page_token (::String) — If non-empty, page_token should contain a next_page_token from a previous ListInstancesResponse.
  • filter (::String) —

    An expression for filtering the results of the request. Filter rules are case insensitive. The fields eligible for filtering are:

    • name
    • display_name
    • labels.key where key is the name of a label

    Some examples of using filters are:

    • name:* --> The instance has a name.
    • name:Howl --> The instance's name contains the string "howl".
    • name:HOWL --> Equivalent to above.
    • NAME:howl --> Equivalent to above.
    • labels.env:* --> The instance has the label "env".
    • labels.env:dev --> The instance has the label "env" and the value of the label contains the string "dev".
    • name:howl labels.env:dev --> The instance's name contains "howl" and it has the label "env" with its value containing "dev".
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
Returns
Raises
  • (::Google::Cloud::Error) — if the REST call 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(request, options = nil) -> ::Gapic::Operation
Pass arguments to update_instance via a request object, either of type UpdateInstanceRequest or an equivalent Hash.
Parameters
  • 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.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
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).
Parameters
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.

#update_instance_config

def update_instance_config(request, options = nil) -> ::Gapic::Operation
def update_instance_config(instance_config: nil, update_mask: nil, validate_only: nil) -> ::Gapic::Operation

Updates an instance config. The returned long-running operation can be used to track the progress of updating the instance. If the named instance config does not exist, returns NOT_FOUND.

Only user managed configurations can be updated.

Immediately after the request returns:

  • The instance config's reconciling field is set to true.

While the operation is pending:

  • Cancelling the operation sets its metadata's 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 config are rejected.
  • Reading the instance config 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 instance config's new values are readable via the API.
  • The instance config's reconciling field becomes false.

The returned long-running operation will have a name of the format <instance_config_name>/operations/<operation_id> and can be used to track the instance config modification. The metadata field type is UpdateInstanceConfigMetadata. The response field type is InstanceConfig, if successful.

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

Overloads 
def update_instance_config(request, options = nil) -> ::Gapic::Operation
Pass arguments to update_instance_config via a request object, either of type UpdateInstanceConfigRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Spanner::Admin::Instance::V1::UpdateInstanceConfigRequest, ::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 update_instance_config(instance_config: nil, update_mask: nil, validate_only: nil) -> ::Gapic::Operation
Pass arguments to update_instance_config 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
  • instance_config (::Google::Cloud::Spanner::Admin::Instance::V1::InstanceConfig, ::Hash) — Required. The user instance config to update, which must always include the instance config name. Otherwise, only fields mentioned in update_mask need be included. To prevent conflicts of concurrent updates, etag can be used.
  • update_mask (::Google::Protobuf::FieldMask, ::Hash) — Required. A mask specifying which fields in InstanceConfig should be updated. The field mask must always be specified; this prevents any future fields in InstanceConfig from being erased accidentally by clients that do not know about them. Only display_name and labels can be updated.
  • validate_only (::Boolean) — An option to validate, but not actually execute, a request, and provide the same response.
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.
