performance issue in one-to-many in hibernate

[Edward Chen]

what is the better way to insert an object in one-to-many ?

for example, one Employee has many Task.

Employee{
  List<Task> taskList;
}

when we add one Task into Employee taskList, we have to load employee and its ALL task, and then save

function save_one_task(new_task){
  Employee employee = dao.load(...);
  List<Task> taskList = dao.loadAllTask(); // line 2

  taskList.add(new_task);

  employee.setTaskList(taskList);

  dao.save(employee);
}

The major performance issue is line 2. we need to load ALL task, maybe 1000, just for adding ONE task.

Do we have a better way to resolve this issue ?

Thanks.

simply create a new task set Its employee id and save it to database
