## Instance Methods

Close httplib2 connections.

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.

Deletes a specific Redis instance. Instance stops serving and data is deleted.

Export Redis instance data into a Redis RDB format file in Cloud Storage. Redis will continue serving during this operation. The returned operation is automatically deleted after a few hours, so there is no need to call DeleteOperation.

Initiates a failover of the primary node to current replica node for a specific STANDARD tier Cloud Memorystore for Redis instance.

Gets the details of a specific Redis instance.

Gets the AUTH string for a Redis instance. If AUTH is not enabled for the instance the response will be empty. This information is not included in the details returned to GetInstance.

Import a Redis RDB snapshot file from Cloud Storage into a Redis instance. Redis may stop serving during this operation. Instance state will be IMPORTING for entire operation. When complete, the instance will contain only data from the imported file. The returned operation is automatically deleted after a few hours, so there is no need to call DeleteOperation.

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.

Retrieves the next page of results.

Updates the metadata and configuration of a specific Redis instance. 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.

Reschedule maintenance for a given instance in a given project and location.

Upgrades Redis instance to the newer Redis version specified in the request.

          2 - v2 error format

    Returns:
      An object of the form:

        { # This resource represents a long-running operation that is the result of a network API call.
      "done": True or False, # If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
      "error": { # The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors). # The error result of the operation in case of failure or cancellation.
        "code": 42, # The status code, which should be an enum value of google.rpc.Code.
        "details": [ # A list of messages that carry the error details. There is a common set of message types for APIs to use.
          {
            "a_key": "", # Properties of the object. Contains field @type with type URL.
          },
        ],
        "message": "A String", # A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.
      },
      "metadata": { # { `createTime`: The time the operation was created. `endTime`: The time the operation finished running. `target`: Server-defined resource path for the target of the operation. `verb`: Name of the verb executed by the operation. `statusDetail`: Human-readable status of the operation, if any. `cancelRequested`: Identifies whether the user has requested cancellation of the operation. Operations that have successfully been cancelled have Operation.error value with a google.rpc.Status.code of 1, corresponding to `Code.CANCELLED`. `apiVersion`: API version used to start the operation. }
        "a_key": "", # Properties of the object. Contains field @type with type URL.
      },
      "name": "A String", # The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the `name` should be a resource name ending with `operations/{unique_id}`.
      "response": { # The normal, successful response of the operation. If the original method returns no data on success, such as `Delete`, the response is `google.protobuf.Empty`. If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`.
        "a_key": "", # Properties of the object. Contains field @type with type URL.
      },
