-- Rebooting a DB instance restarts the database engine service. A reboot
-- also applies to the DB instance any modifications to the associated DB
-- parameter group that were pending. Rebooting a DB instance results in a
-- momentary outage of the instance, during which the DB instance status is
-- set to rebooting. If the RDS instance is configured for MultiAZ, it is
-- possible that the reboot will be conducted through a failover. An Amazon
-- RDS event is created when the reboot is completed.
--
-- If your DB instance is deployed in multiple Availability Zones, you can
-- force a failover from one AZ to the other during the reboot. You might
-- force a failover to test the availability of your DB instance deployment
-- or to restore operations to the original AZ after a failover occurs.
--
-- The time required to reboot is a function of the specific database
-- engine\'s crash recovery process. To improve the reboot time, we
-- recommend that you reduce database activities as much as possible during
-- the reboot process to reduce rollback activity for in-transit
-- transactions.
