[GitHub] [airflow] collinmcnulty commented on pull request #25101: Incorrect definition of parallelism in default_airflow.cfg

   My concern with tying it to number of schedulers is that then the limit on concurrent tasks is implicit (num_schedulers * parallelism) instead of being directly visible. It also means that deciding you don't need HA (for example) means you have to change the configuration even if one scheduler actually could handle the full load of tasks. 
   
   It seems like surprising behavior, which I would want to avoid.
