Hi, Talked with Henry Nash and Jamie Lennox on IRC, I have created two BPs to manage the keystone tokens: 1. https://blueprints.launchpad.net/keystone/+spec/periodically-flush-expired-token which is used to delete expired token 2. https://blueprints.launchpad.net/keystone/+spec/reuse-token which will re-use valid token These two BPs will help us to reduce the token records in token table enormously. I have put some ideas on the BP description. Any comments are welcome. Regards, Yong Sheng Gong -------------- next part -------------- An HTML attachment was scrubbed...
