Is RDS instance in 'pending reboot' status after parameter group change automatically rebooted?

Question

I changed a parameter in a MySQL 8.0 RDS instance parameter group.

I chose the pending-reboot apply method to avoid downtime, and now the parameter group is marked as "pending reboot" in the configuration tab of the rds instance.

So I was wondering: given that my rds instance specifies a maintenance window, will it be automatically rebooted during such maintenance window?

Or will I have to reboot it myself?

Thanks in advance!

Answer 1

I found the answer on AWS doc:

The pending-reboot status doesn't result in an automatic reboot during the next maintenance window. To apply the latest parameter changes to your DB instance, reboot the DB instance manually.

Answer 2

pending-reboot for RDS instance we must reboot manually. maintenance window will not take care of it.

Answer 3

For anyone looking at this question in the future, the instance was not restarted.

As far as I understood from the documentation, maintenance windows only apply to Amazon-issued maintenance.
