commit 53bb53a814324234aa4b798651a616e310396221 Author: liuhongjiang <[email protected]> Date: Mon Jun 13 08:11:16 2016 +0800 Added cache for id mapping manager When using a identity driver without providing uuid, and using default sql id mapping driver, if there are lots of users, then it may take minutes to list users. Adding cache to the id mapping manager can improve the performance. After adding the cache, when listing 12000 users though the keystone api, and the time is reduced from about 75 seconds to 20 seconds. Closes-Bug: #1582585 Change-Id: I72eeb88926d8babb09a61e99f6f594371987f393 ** Changed in: keystone Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Identity (keystone). https://bugs.launchpad.net/bugs/1582585 Title: the speed of query user from ldap server is very slow Status in OpenStack Identity (keystone): Fix Released Bug description: In our project, the speed of query user from ldap server is very slow,our ldap user number is 12,000,the query costs almost 45 seconds The reason is that keystone will generate the uuid for the ldap users one by one and insert db.And second query time later,it also goes to db,not use the cache. So adding the cache to improve the query speed After adding @MEMOIZE to the following function https://github.com/openstack/keystone/blob/master/keystone/identity/core.py#L580. First query time almost costs 50 seconds,but second query time later it only costs 7 seconds. So it is very necessary to improve this feature To manage notifications about this bug go to: https://bugs.launchpad.net/keystone/+bug/1582585/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
