Class CloudRedisClusterClient (2.19.0-rc)

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.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

ListClusters(std::string const &, Options)

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.

Parameters
NameDescription
parent std::string const &

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.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
TypeDescription
StreamRange< google::cloud::redis::cluster::v1::Cluster >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.redis.cluster.v1.Cluster, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListClusters(google::cloud::redis::cluster::v1::ListClustersRequest, Options)

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.

Parameters
NameDescription
request google::cloud::redis::cluster::v1::ListClustersRequest

Unary RPCs, such as the one wrapped by this function, receive a single request proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.redis.cluster.v1.ListClustersRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
TypeDescription
