code: def InitPathInfos(self, client_id, path_infos):
      
      self.ClearPathHistory(client_id, path_infos)
      self.WritePathInfos(client_id, path_infos)
docs: Initializes a collection of path info records for a client.
  
      Unlike `WritePathInfo`, this method clears stat and hash histories of paths
      associated with path info records. This method is intended to be used only
      in the data migration scripts.
  
      Args:
        client_id: A client identifier for which the paths are to be initialized.
        path_infos: A list of `rdf_objects.PathInfo` objects to write.
