// Google Cloud Memorystore for Redis v1beta1
//
// 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 refering to a GCP `region`; for example:
// * `projects/redpepper-1290/locations/us-central1/instances/my-redis`
service CloudRedis {
  // Lists all Redis instances 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.
