-/**
- * Creates a Redis instance based on the specified tier and memory size.
- *
- * By default, the instance is accessible from the project's
- * [default network](https://cloud.google.com/vpc/docs/vpc).
- *
- * The creation is executed asynchronously and callers may check the returned
- * operation to track its progress. Once the operation is completed the Redis
- * instance will be fully functional. The completed longrunning.Operation will
- * contain the new instance object in the response field.
- *
- * The returned operation is automatically deleted after a few hours, so there
- * is no need to call DeleteOperation.
- *
- * @param string $formattedParent      The resource name of the instance location using the form:
- *                                     `projects/{project_id}/locations/{location_id}`
- *                                     where `location_id` refers to a GCP region. Please see
- *                                     {@see CloudRedisClient::locationName()} for help formatting this field.
- * @param string $instanceId           The logical name of the Redis instance in the customer project
- *                                     with the following restrictions:
- *
- *                                     * Must contain only lowercase letters, numbers, and hyphens.
- *                                     * Must start with a letter.
- *                                     * Must be between 1-40 characters.
- *                                     * Must end with a number or a letter.
- *                                     * Must be unique within the customer project / location
- * @param string $instanceName         Unique name of the resource in this scope including project and
- *                                     location using the form:
- *                                     `projects/{project_id}/locations/{location_id}/instances/{instance_id}`
- *
- *                                     Note: Redis instances are managed and addressed at regional level so
- *                                     location_id here refers to a GCP region; however, users may choose which
- *                                     specific zone (or collection of zones for cross-zone instances) an instance
- *                                     should be provisioned in. Refer to [location_id][google.cloud.redis.v1beta1.Instance.location_id] and
- *                                     [alternative_location_id][google.cloud.redis.v1beta1.Instance.alternative_location_id] fields for more details.
