 """Scan database for resolving Data objects and process them. This is submitted as a task to the manager's channel workers. :param data_id: Optional id of Data object which (+ its children) should be processes. If it is not given, all resolving objects are processed. :param run_sync: If ``True``, wait until all processes spawned from this point on have finished processing. If no processes are spawned, this results in a deadlock, since counts are handled on process finish. :param save_settings: If ``True``, save the current Django settings context to the global state. This should never be ``True`` for "automatic" calls, such as from Django signals, which can be invoked from inappropriate contexts (such as in the listener). For user code, it should be left at the default value. The saved settings are in effect until the next such call. """
