Overview

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

Instance Method Details

#apply_parameters(request, options = nil) ⇒ ::Gapic::Operation #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.

Examples:

Basic example

require "google/cloud/memcache/v1beta2"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Memcache::V1beta2::CloudMemcache::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Memcache::V1beta2::ApplyParametersRequest.new

# Call the apply_parameters method.
result = client.apply_parameters 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

Overloads:

  • #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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #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) (defaults to: nil) —

      Required. Resource name of the Memcached instance for which parameter group updates should be applied.

    • node_ids (::Array<::String>) (defaults to: nil) —

      Nodes to which the instance-level parameter group is applied.

    • apply_all (::Boolean) (defaults to: nil) —

      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.

#delete_instance(request, options = nil) ⇒ ::Gapic::Operation #delete_instance(name: nil) ⇒ ::Gapic::Operation

Deletes a single Instance.

Examples:

Basic example

require "google/cloud/memcache/v1beta2"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Memcache::V1beta2::CloudMemcache::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Memcache::V1beta2::DeleteInstanceRequest.new

# Call the delete_instance method.
result = client.delete_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

      The maximum number of items to return.

      If not specified, a default value of 1000 will be used by the service. Regardless of the page_size value, the response may include a partial list and a caller should only rely on response's next_page_token to determine if there are more instances left to be queried.

    • page_token (::String) (defaults to: nil) —

      The next_page_token value returned from a previous List request, if any.

    • filter (::String) (defaults to: nil) —

  • #update_instance(update_mask: nil, resource: 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:

  • (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_parameters(request, options = nil) ⇒ ::Gapic::Operation #update_parameters(name: nil, update_mask: nil, parameters: nil) ⇒ ::Gapic::Operation

Updates the defined Memcached parameters for an existing instance. This method only stages the parameters, it must be followed by ApplyParameters to apply the parameters to nodes of the Memcached instance.

Examples:

Basic example

require "google/cloud/memcache/v1beta2"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Memcache::V1beta2::CloudMemcache::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Memcache::V1beta2::UpdateParametersRequest.new

# Call the update_parameters method.
result = client.update_parameters 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

Overloads:

  • #update_parameters(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to update_parameters via a request object, either of type UpdateParametersRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Memcache::V1beta2::UpdateParametersRequest, ::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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #update_parameters(name: nil, update_mask: nil, parameters: nil) ⇒ ::Gapic::Operation

    Pass arguments to update_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:

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.
