Google Cloud Memorystore for Memcached API - Class Google::Cloud::Memcache::V1beta2::CloudMemcache::Client (v0.9.1)

Reference documentation and code samples for the Google Cloud Memorystore for Memcached API class Google::Cloud::Memcache::V1beta2::CloudMemcache::Client.

Client for the CloudMemcache service.

Configures and manages Cloud Memorystore for Memcached instances.

The memcache.googleapis.com service implements the Google Cloud Memorystore for Memcached API and defines the following resource model for managing Memorystore Memcached (also called Memcached below) instances:

  • The service works with a collection of cloud projects, named: /projects/
  • Each project has a collection of available locations, named: /locations/
  • Each location has a collection of Memcached instances, named: /instances/*
  • As such, Memcached instances are resources of the form: /projects/{project_id}/locations/{location_id}/instances/{instance_id}

Note that location_id must be a GCP region; for example:

  • projects/my-memcached-project/locations/us-central1/instances/my-memcached

Methods

.configure

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

Configure the CloudMemcache 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 CloudMemcache clients
::Google::Cloud::Memcache::V1beta2::CloudMemcache::Client.configure do |config|
  config.timeout = 10.0
end

#apply_parameters

def apply_parameters(request, options = nil) -> ::Gapic::Operation
def apply_parameters(name: nil, node_ids: nil, apply_all: nil) -> ::Gapic::Operation

ApplyParameters restarts the set of specified nodes in order to update them to the current set of parameters for the Memcached Instance.

Overloads 
def apply_parameters(request, options = nil) -> ::Gapic::Operation
Pass arguments to apply_parameters via a request object, either of type ApplyParametersRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Memcache::V1beta2::ApplyParametersRequest, ::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 apply_parameters(name: nil, node_ids: nil, apply_all: nil) -> ::Gapic::Operation
Pass arguments to apply_parameters 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
  • name (::String) — Required. Resource name of the Memcached instance for which parameter group updates should be applied.
  • node_ids (::Array<::String>) — Nodes to which the instance-level parameter group is applied.
  • apply_all (::Boolean) — Whether to apply instance-level parameter group to all nodes. If set to true, users are restricted from specifying individual nodes, and ApplyParameters updates all nodes within the instance.
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.
