> It seems that Airflow scheduler is creating worker pod sequentially(one pod per scheduler loop) in Kubernetes executors sync function which is called from base executors.heartbeat() function.
> One enhancement could be to create the k8 pod in batches where batch size can be configured through airflow.cfg file
