I was just investigating some performance issues on one of the main enwiki slaves (db60) and see several > hour long dump queries running from storage4: | 9526634472 | wikiadmin | 10.0.10.4:35311 | enwiki | Query | 3801 | Writing to net | SELECT /* WikiExporter::dumpFrom */ * FROM `page` INNER JOIN `revision` ON ((page_id=rev_page)) WHERE page_id >= 465001 AND page_id < 665001 ORDER BY page_id ASC db.php contains: 'groupLoadsByDB' => array( 'enwiki' => array( 'watchlist' => array( 'db36' => 1, ), 'recentchangeslinked' => array( 'db36' => 1, ), 'contributions' => array( 'db36' => 1, ), 'dump' => array( 'db36' => 1, ), ) Which was intended to direct all enwiki dump queries to db36, but it looks like this is no longer respected. Please fix.
