   the trigger rule `none_failed_or_skipped` is a solution to your use case  -> https://airflow.apache.org/docs/apache-airflow/2.1.2/concepts/dags.html?highlight=none_failed_or_skipped#trigger-rules
   
   ```python
   task_at_least_one_previous_succes = SomeOperator(
                                                                    trigger_rule = "none_failed_or_skipped",
                                                                    ....
                                                                  )
   
   [task_a,task_b,task_c] >> task_at_least_one_previous_succeed
   ```
