BenjaminYong opened a new issue, #47844:
URL: https://github.com/apache/airflow/issues/47844

   ### Description
   
   An Airflow API endpoint to programatically reserialize dags, aligned with 
the `airflow dags reserialize `CLI command:
   
https://airflow.apache.org/docs/apache-airflow/stable/cli-and-env-variables-ref.html#reserialize
 
   
   ### Use case/motivation
   
   Currently, I must exec into my Airflow webserver in order to run the CLI 
command to refresh dags. 
   
   However, I already have an Airflow client programatically communicating to 
the Airflow webserver API. It would be great to be able to request the API to 
refresh dags when required.
   
   As a temporary solution, I have set a low interval of 1s for:
   - min_serialized_dag_update_interval
   - min_serialized_dag_fetch_interval
   
   But have found high constant resource usage as a result to the Airflow 
services.
