coufon commented on issue #5743: [AIRFLOW-5088][AIP-24] Persisting serialized 
DAG in DB for webserver scalability
URL: https://github.com/apache/airflow/pull/5743#issuecomment-523990605
 
 
   > Another idea: right now the `airflow webserver` cycles the gunicorn 
workers every 120s (by default) -- if we aren't loading the dag files in most 
case do we need that anymore?
   > 
   > Additionally should we remove the "Refresh" buttons from the webserver now 
too?
   
   Yes. We can have a thread that refresh DAGs from DB to the dagbag in memory 
periodically. After having that we don't need to restart gunicorn workers 
(e.g., setting refresh interval to one hour).
