[07:57:13] Amir1: regarding data loss, any common factor yet, or does it seem random / evenly distributed? ref T364245 [07:57:13] T364245: Recentchanges and cu_changes tables are occasionally missing revisions on multiple wikis - https://phabricator.wikimedia.org/T364245 [07:57:56] Looking at nlwiki, it seems evenly distributed, no obvious common cause yet. If truely no common factor, it would imply some kind of race condition, timeout, pod shutdown etc [07:59:15] https://quarry.wmcloud.org/query/100476 [08:02:04] by page_namespace; https://phabricator.wikimedia.org/P86760 [08:04:02] Main 0: 5%, Talk 1: 20%, User 2: 4%, User_talk 3: 25% [08:05:16] Project 4: 2%, Template 10: 10% [08:05:53] Category 14: 42% [08:08:45] looking at enwiktionary for comparison [08:09:37] Category 99% loss [08:10:01] Looks like the most affected are probably also logged-in or more advanced users [08:13:21] no.. [08:13:28] but logged-in users are more likely to create pages [08:13:36] checking rev_parent_id [08:14:09] yep [08:14:13] 100% have rev_parent_id=0 [08:14:23] or close to 100% given the problem is growing in real time [08:24:54] Hm.. [08:25:03] Isn't mw.new for page creation? [08:42:45] yeah, so the problem isn't 5% globally, much less [08:42:50] it's more like 2%, still huyge [20:35:03] Krinkle: thanks for investigating and catch rc.new. I agree it still needs fixing. I was traveling and haven't looked too deep. I will take a deeper look soonTM
