Hi Stackers, I'm curious to find out if we have anyone already using pt-archiver to purge Keystone tokens in MySQL + Galera in production under heavy load with Galera in multi-master mode. I'm referring to the tripleo script that uses pt-archiver to clean up keystone tokens here: https://github.com/openstack/tripleo-image-elements/blob/master/elements/keystone/cleanup-keystone-tokens.sh I have two questions: Does this need to be run on every Galera host or just against one? Second, does it have any major impact on production? What is the likelihood of causing issues with API DB transactions while pt-archiver is purging keystone tokens table? Thanks in advance! -Matthew Mosesohn -------------- next part -------------- An HTML attachment was scrubbed...
