### Method Details

`create(parent, body=None, instanceId=None, x__xgafv=None)`

    Creates a Redis instance based on the specified tier and memory size.

    By default, the instance is accessible from the project's
    [default network](/compute/docs/networks-and-firewalls#networks).

    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. 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.

    Args:
      parent: string, Required. The resource name of the instance location using the form:
        `projects/{project_id}/locations/{location_id}`
    where `location_id` refers to a GCP region. (required)
      body: object, The request body.

            # [network](/compute/docs/networks-and-firewalls#networks) to which the

`import_(name, body=None, x__xgafv=None)`

    Import a Redis RDB snapshot file from Cloud Storage into a Redis instance.

    Redis may stop serving during this operation. Instance state will be

    The returned operation is automatically deleted after a few hours, so
    there is no need to call DeleteOperation.

    The location should have the following format:

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.

`patch(name, body=None, updateMask=None, x__xgafv=None)`

    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.

    location using the form:
        `projects/{project_id}/locations/{location_id}/instances/{instance_id}`

    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
