NAME

object-expirer.conf - configuration file for the openstack-swift object exprier daemon

SYNOPSIS

object-expirer.conf

DESCRIPTION

This is the configuration file used by the object expirer daemon. The daemon's function is to query the internal hidden expiring_objects_account to discover objects that need to be deleted and to then delete them.

The configuration file follows the python-pastedeploy syntax. The file is divided into sections, which are enclosed by square brackets. Each section will contain a certain number of key/value parameters which are described later.

Any line that begins with a '#' symbol is ignored.
