Google Cloud Memorystore for Redis V1 API - Class Google::Cloud::Redis::Cluster::V1::CloudRedisCluster::Client (v0.3.0)

Reference documentation and code samples for the Google Cloud Memorystore for Redis V1 API class Google::Cloud::Redis::Cluster::V1::CloudRedisCluster::Client.

Client for the CloudRedisCluster service.

Configures and manages Cloud Memorystore for Redis clusters

Google Cloud Memorystore for Redis Cluster

The redis.googleapis.com service implements the Google Cloud Memorystore for Redis API and defines the following resource model for managing Redis clusters:

  • 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 Redis clusters, named: /clusters/*
  • As such, Redis clusters are resources of the form: /projects/{project_id}/locations/{location_id}/clusters/{instance_id}

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

  • projects/redpepper-1290/locations/us-central1/clusters/my-redis

We use API version selector for Flex APIs

  • The versioning strategy is release-based versioning
  • Our backend CLH only deals with the superset version (called v1main)
  • Existing backend for Redis Gen1 and MRR is not touched.

Methods

.configure

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

Configure the CloudRedisCluster 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 CloudRedisCluster clients
::Google::Cloud::Redis::Cluster::V1::CloudRedisCluster::Client.configure do |config|
  config.timeout = 10.0
end

#configure

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

Configure the CloudRedisCluster 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_cluster

def create_cluster(request, options = nil) -> ::Gapic::Operation
def create_cluster(parent: nil, cluster_id: nil, cluster: nil, request_id: nil) -> ::Gapic::Operation

Creates a Redis cluster based on the specified properties. The creation is executed asynchronously and callers may check the returned operation to track its progress. Once the operation is completed the Redis cluster will be fully functional. The completed longrunning.Operation will contain the new cluster object in the response field.

The returned operation is automatically deleted after a few hours, so there is no need to call DeleteOperation.

Overloads 
def create_cluster(request, options = nil) -> ::Gapic::Operation
Pass arguments to create_cluster via a request object, either of type Google::Cloud::Redis::Cluster::V1::CreateClusterRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Redis::Cluster::V1::CreateClusterRequest, ::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_cluster(parent: nil, cluster_id: nil, cluster: nil, request_id: nil) -> ::Gapic::Operation
Pass arguments to create_cluster 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 resource name of the cluster location using the form: projects/{project_id}/locations/{location_id} where location_id refers to a GCP region.
  • cluster_id (::String) —

    Required. The logical name of the Redis cluster in the customer project with the following restrictions:

    • Must contain only lowercase letters, numbers, and hyphens.
    • Must start with a letter.
    • Must be between 1-63 characters.
    • Must end with a number or a letter.
    • Must be unique within the customer project / location
  • cluster (::Google::Cloud::Redis::Cluster::V1::Cluster, ::Hash) — Required. The cluster that is to be created.
  • request_id (::String) — Idempotent request UUID.
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.

Lists all Redis clusters owned by a project in either the specified location (region) or all locations.

The location should have the following format:

  • projects/{project_id}/locations/{location_id}

If location_id is specified as - (wildcard), then all regions available to the project are queried, and the results are aggregated.

Overloads 
def list_clusters(request, options = nil) -> ::Gapic::PagedEnumerable<::Google::Cloud::Redis::Cluster::V1::Cluster>
Pass arguments to list_clusters via a request object, either of type ListClustersRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Redis::Cluster::V1::ListClustersRequest, ::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.

    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 clusters left to be queried.

  • page_token (::String) — The next_page_token value returned from a previous [ListClusters][CloudRedis.ListClusters] request, if any.
Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
Returns
Raises
