Hi, WikiGrok[0] has been successfully deployed to the English Wikipedia. Along with it a first campaign[1] was deployed. Now database is being slowly populated with suggestions:

Pages are getting updated when edited (null edit works, but not action=purge). According to estimations made with WikiData Query[2], the number of potentially affected pages is approximately 33,000. If really needed, we could whip up a script to null-edit these pages from server side in a controlled manner, but I would like to have more data on performance and memory consumption first.
== Monitoring == * Graphite: MediaWiki -> WikiGrok * Exceptions from WikiData: type:mobile in Logstash.
== Firefighting == Most of potentially performance-scary/error causing code with can be disabled by commenting out $wgWikiGrokSlowCampaigns in wmf-config/mobile.php. If shit hits fan really hard, whole extension can be disabled through the usual means, with $wmgUseWikiGrok.
== Next steps == I'm working on DB storage for questions[3] which will allow us to avoid abusing page_props and give features such as "find me pages that could use this type of fixes" and "find me a random page to fix".
