   Airflow uses a database for communication, which means there is no efficient way to send messages from the scheduler to the webserver. If we wanted to do it right, we would have to have a queue where the scheduler / worker could publish information, and the webserver could respond to these messages and forward to the user. This is an interesting change, but would require a major architectural change. For now, we have to use HTTP/database pooling
