Since we no longer have few wikireplica servers with only one instance each, the maintain-dbusers script or a similar faculty needs to maintain the max_user_connections of those users who have gone through our approval process for increases.
Normally, we record those at modules/role/templates/mariadb/grants/wiki-replicas.sql in puppet. Currently there are only 3 of them.
-- quarry user granted 48 connections #T180141 GRANT USAGE ON *.* TO 's52788'@'%' WITH MAX_USER_CONNECTIONS 48; -- user for wikiscan granted 15 connections T227462 GRANT USAGE ON *.* TO 'u12903'@'%' WITH MAX_USER_CONNECTIONS 15; -- catscan2 (petscan) user granted 40 connections T255730 GRANT USAGE ON *.* TO 's51156'@'%' WITH MAX_USER_CONNECTIONS 40;
