.. program:: purge
.. option:: -h, --help
Show help for purge and exit.
.. option:: -d, --age-in-days
The number of days (starting from today) before which we consider soft
deleted objects as expired and should hence be erased. By default, all
objects soft deleted are considered expired. This can be useful as removing
a significant amount of objects may cause a performance issues.
.. option:: -n, --max-number
The maximum number of database objects we expect to be deleted. If exceeded,
this will prevent any deletion.
.. option:: -t, --audit-template
Either the UUID or name of the soft deleted audit template to purge. This
will also include any related objects with it.
.. option:: -e, --exclude-orphans
This is a flag to indicate when we want to exclude orphan objects from
deletion.
.. option:: --dry-run
This is a flag to indicate when we want to perform a dry run. This will show
the objects that would be deleted instead of actually deleting them.
This command will purge the current database by removing both its soft deleted
and orphan objects.
