On the keystone side, this is specifically addressed by https://blueprints.launchpad.net/keystone/+spec/list-limiting
On the horizon side, horizon should issue queries to keystone with as many filters as reasonably possible to avoid hitting the truncation behavior implemented above. ** Changed in: keystone Status: New => Invalid -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to Keystone. https://bugs.launchpad.net/bugs/1278920 Title: Bad performance when editing project members Status in OpenStack Dashboard (Horizon): Confirmed Status in OpenStack Identity (Keystone): Invalid Bug description: In an envrionment with where there are more than 1000 users, edito project members dialog performs a query for each user to get its roles, which results in a bad performance. There are some alternatives to fix in the UI side, but we could also fix in keystone with an extension, for example. Please reassign to keystone if needed. In the best scenario, Horizon takes 8 secs to render the UI with 1000 users and 2 assigned users. On the other hand, it takes 1 min to show the UI with 1000 users and 1000 assigned users.
