Marostegui added a comment to T366959: 1.43.0-wmf.14 deployment blockers.

My understanding of comments in T370304 and of the IRC backlog in #mediawiki_security is that the train can proceed.

Marostegui added a comment to T366959: 1.43.0-wmf.14 deployment blockers.

That's weird, s1 is enwiki and that's group2. I don't know anything that would do a cross wiki read to enwiki from a group1 wiki not to mention writes. Do we have some samples on what was overwhelming s1?

Marostegui added a comment to T370304: Exception caught inside exception handler: Wikimedia\Rdbms\DBUnexpectedError: Database servers in extension1 are overloaded..

I would recommend disabling circuit breaking on x1 as it seems to me that the cure is worse than the ailment. @Marostegui @Ladsgroup what do you think?

One main reason for this is that one replica has been depooled for hw issue. I need to spend some time and figure out a way to actually allow disabling specific sections from circuit breaking (I want to do it for es sections too). On paper, each LB has its own config so it should be easy but nope, it is quite complicated. I'll see what I can do when I'm back from vacation.

Marostegui updated subscribers of T366959: 1.43.0-wmf.14 deployment blockers.

A few minutes after the deployment quite a number of s1 replicas started to show lag - the master started to have contention too.

Is this table really needed or is it a code problem? There're more tickets about the reported error the mentioned T370219: DBQueryError marking page for translation: Table 'mediawikiwiki.translate_cache' doesn't exist and an older one T272428: Error 1146: Table 'mediawikiwiki.translate_cache' doesn't exist

After a week of capturing some traffic on API and main traffic - apart from the usual recentchanges queries, I've captured some slow queries which have the same query plans on 10.6 hosts. I'm going to increase a bit more db2136's weight to see how it performs under a bit more pressure
