Title: tenant usage information api is consuming lot of memory Status in OpenStack Compute (nova): Invalid Bug description: I have noticed that when a tenant usage information API is invoked for a particular tenant owning large number of instances (both active & terminated), then I see a sudden increase in nova-api process memory consumption from 500 MB up to 2.3 GB. It is due to a SQL retrieving large number of records of instance_system_metadata for instances using where in clause. At the time of getting tenant usage information, I had approx. 120,000 instances in the db for a particular tenant (few were active and remaining terminated) Also in this plugin, it unnecessarily gets following information of the instances from the db further degrading the performance of the API. 1. metadata 2. info_cache 3. security_groups To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1367944/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
