Hello all users of Airflow,
We need to perform some scheduled maintenance on all of our Airflow
instances, so I'm scheduling a maintenance window for tomorrow at 08:30
UTC and I expect the work to take no more than 30 minutes. The work
involves a reboot of the shared PostgreSQL database that serves all of
our instances, as well as a reboot of some instances themselves.
I will pause all active DAGs on all Airflow instances prior to the work,
allow some time for running tasks to complete, then un-pause the DAGs
afterwards.
Naturally, you are also free to pause your own DAGs prior to the
maintenance and un-pause them afterwards, should you wish to minimize
the risk of disruption.
Please do let me know if there is anything specific that you would like
me to check, either before or after this maintenance.
Kind regards,
Ben
