У меня есть таблица, в которой более 300 тысяч разделов. Когда я пытаюсь добавить новый столбец, как показано ниже, он работает в течение многих часов, а затем дает сбой. Metastor rds находится на mysql, а таблица разделов содержит более 5 миллионов строк. Кто-нибудь сталкивался с этим?
alter table tablea add columns(col1 string) cacade;
