У меня есть 2 мастера экземпляров mariadb и один раб. Репликация mixed. SLAVE lag = 0 Seconds_Behind_Master: 0 У меня есть экземпляр maxscale, который должен разделять запросы SELECT между главным и подчиненным, но все запросы SELECT отправляются ведущему.
Не могли бы вы помочь мне решить эту проблему?
Вот мои maxscale.cnf
