What about InnoDB? Or RocksDB? Or any other transactional engine?

There is flag HTON_SUPPORT_LOG_TABLES, which is checked earlier in mysql_alter_table().

It's not checked on CREATE, only on ALTER, so one can easily bypass this check. And, anyway, why an engine would not support log tables? Only because it's transactional? Regards, Sergei VP of MariaDB Server Engineering and security@mariadb.org
