[GitBox <gi...@apache.org>]

uranusjr opened a new issue #19670:
URL: https://github.com/apache/airflow/issues/19670


   ### Body
   
   Continuation of #19378
   
   https://github.com/apache/airflow/pull/19378#issuecomment-966898703
   > If the user uses `DecoratedOperator` as shown below through [TaskFlow API](https://airflow.apache.org/docs/apache-airflow/stable/tutorial_taskflow_api.html), there seems to be no way to block XCom return value logs.
   > 
   > ```python
   > @task
   > def my_task(): # Guess it is `_PythonDecoratedOperator`
   >     # ... process
   >     return large_data
   > 
   > 
   > with DAG(...) as dag:
   >     data = my_task() # It will make a huge log messages on Airflow UI
   >     my_second_task(data)
   > ```
   > 
   > so, I think additional work will be required in a separate PR for TaskFlow API users.
