This is often mentioned as one of those items which catches every OpenStack cloud operator at some time. It's not clear to me that there could not be a scheduled job built into the system with a default frequency (configurable, ideally).
If we are all configuring this as a cron job, is there a reason that it could not be built into the code ?

The accumulation of expired tokens considerably increases the database size and might degrade service performance, particularly in environments with limited resources. We recommend that you use cron to configure a periodic task that purges expired tokens hourly: # (crontab -l -u keystone 2>&1 | grep -q token_flush) || \ echo '@hourly /usr/bin/keystone-manage token_flush >/var/log/keystone/ keystone-tokenflush.log 2>&1' \ >> /var/spool/cron/keystone Mike Smith Principal Engineer, Website Systems Overstock.com<http://Overstock.com> On Jan 24, 2015, at 10:03 AM, Daniel Comnea <comnea.d...@gmail.com<mailto:comnea.d...@gmail.com>> wrote: Hi all, I just bumped into Sebastien's blog where he suggested a cron job should run in production to tidy up expired tokens - see blog[1] Could you please remind me if this is still required in IceHouse/ Juno?
