 """ Updates an app profile within an instance. Example: Args: app_profile (Union[dict, ~google.cloud.bigtable_admin_v2.types.AppProfile]):
 The app profile which will (partially) replace the current value. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.bigtable_admin_v2.types.AppProfile` update_mask (Union[dict, ~google.cloud.bigtable_admin_v2.types.FieldMask]):
 The subset of app profile fields which should be replaced. If unset, all fields will be replaced. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.bigtable_admin_v2.types.FieldMask` ignore_warnings (bool):
 If true, ignore safety checks when updating the app profile. retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Returns: A :class:`~google.cloud.bigtable_admin_v2.types._OperationFuture` instance. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
