We have been using multiple kubernetes schedulers in order to improve the autoscaling performance of our clusters. This includes using separate schedulers for evictable pods (such as the airflow scheduler or webserver) and non-evictable pods (such as spark drivers or Airflow kubernetesExecutor pods).
Currently the Airflow helm chart allows us to set the schedulerName (added in #33843) but this can only be set globally across all airflow components. We would like to override this for only the workers, similar to how other fields such as node selectors and affinity can be overridden.
For consistency with other configuration options under
workers, I have added this override to both the pod template file and the celery workers deployment.We could also support configuring an overriding schedulerName for all other components (webserver, scheduler, etc) but I can't think of any need for this currently.
