`router.autoDeleteAge`::
A date math expression that results in the oldest collections getting deleted automatically.
The date math is relative to the timestamp of a newly created collection (typically close to the current time),
and thus this must produce an earlier time via rounding and/or subtracting.
Collections to be deleted must have a time range that is entirely before the computed age.
Collections are considered for deletion immediately prior to new collections getting created.
Example: `/DAY-90DAYS`. The default is not to delete.

The * can be replaced with any parameter from the <<create,CREATE>> command except `name`. All other fields
