It is still mentioned in the Juno installation docs:

By default, the Identity service stores expired tokens in the database indefinitely. 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

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? (i kind of remember i've seen some work being done in this direction but i can't find the emails)


Thanks,
Dani
