Мы тестируем сбой Galera, чтобы воспроизвести одну из проблем продукта при удалении записи. Версия 10.1.32
Может кто-нибудь помочь нам с сценариями сбоя кластера Galera при удалении записей. Когда он падает? Это связано с внешним ключом или wsrep_slave_threads?
Пожалуйста, предоставьте любую помощь.
