Subject Re: Good practices around restarting scheduler and server of airflow
Date Thu, 13 Jul 2017 20:58:31 GMT
Airbnb switched to running the scheduler without restarts about a month
ago, and it is working well. The one issue you might hit is if you are
using a version of Celery with a bug (where workers will pull off tasks
even if they don't have space to run them), tasks can potentially be lost
once they are sent to your Celery backend. With restarts these tasks are
automatically resent.
