* Configures and manages Cloud Memorystore for Redis instances
*
* Google Cloud Memorystore for Redis v1
*
* 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`
*
* @class
* @memberof v1
