  • Mediawiki history Druid data source switch
  • Check for newly created wikis
  • Add _REFINED flags for events that contribute to the wmf.wikidata_item_page_link dataset. (this is not even documented anywhere outside of email)
  • We run the false positive checker for webrequest loss probably once or more a month. This could be partially automated, if the script finds that all instances of loss are false positives, the job could be automatically rerun. If we do this automatically, we could update the webrequest_sequence_stats table with the results, allowing for trend tracking on top of that table. Currently if you try to analyze data loss over time you find lots of noise with high % loss due to host restarts, etc.
