secondsUntilAutoPause

The number of seconds an Aurora Serverless v2 DB instance must be idle before Aurora attempts to automatically pause it. This property is only shown when the minimum capacity for the cluster is set to 0 ACUs. Changing the minimum capacity to a nonzero value removes this property. If you later change the minimum capacity back to 0 ACUs, this property is reset to its default value unless you specify it again.

This value ranges between 300 seconds (five minutes) and 86,400 seconds (one day). The default is 300 seconds.
