Not sure if this is an appropriate place to discuss this but I'm not
able to run this query:
https://quarry.wmflabs.org/query/24267
Even a minor part of this query like below needs a significant time to
complete.
SELECT count(*) as review_count, log_actor
FROM logging
WHERE log_type = 'review' AND log_action = 'approve'
GROUP BY log_actor
I tried with logging_userindex but that don't seem to help. Any chances
on adding extra indexes to make such queries work? I think querying
log_type and log_actor should be quite common for various user stats.
Even this takes almost 200 seconds to complete:
SELECT count(*) as review_count, log_actor
FROM logging_userindex
WHERE log_type = 'review' AND log_action = 'approve'
AND log_timestamp >= 20190101000000
AND log_timestamp <= 20190101235959
GROUP BY log_actor
Also note that the query 24267 used to work in January 2020. I searched
through the list, but haven't found any changes related to the logging
table since January.
Cheers,
Nux.
