            # The `redis.googleapis.com` service implements the Google Cloud Memorystore
            # for Redis API and defines the following resource model for managing Redis
            # 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 Redis instances, named: `/instances/*`
            # * As such, Redis instances are resources of the form:
            #   `/projects/{project_id}/locations/{location_id}/instances/{instance_id}`
            #
            # Note that location_id must be referring to a GCP `region`; for example:
            # * `projects/redpepper-1290/locations/us-central1/instances/my-redis`

              # This class represents the configuration for CloudRedis REST,
              # providing control over timeouts, retry behavior, logging, transport
              # parameters, and other low-level controls. Certain parameters can also be
              # applied individually to specific RPCs. See
              # {::Google::Cloud::Redis::V1::CloudRedis::Rest::Client::Configuration::Rpcs}
              # for a list of RPCs that can be configured independently.
              #
              # Configuration can be applied globally to all clients, or to a single client
              # on construction.
              #
              # @example
              #
              #   # Modify the global config, setting the timeout for
              #   # list_instances to 20 seconds,
              #   # and all remaining timeouts to 10 seconds.
