<div dir="ltr"><div><div><div>Hi Stackers,<br><br>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:<br>
<a href="https://github.com/openstack/tripleo-image-elements/blob/master/elements/keystone/cleanup-keystone-tokens.sh">https://github.com/openstack/tripleo-image-elements/blob/master/elements/keystone/cleanup-keystone-tokens.sh</a><br>
<br></div>I have two questions: <br>Does this need to be run on every Galera host or just against one?<br>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?<br>
<br></div>Thanks in advance!<br><br></div>-Matthew Mosesohn<br><div><div><br><br></div></div></div>
