- mariadb-dump utility performs logical backups by producing set of sql statements that can be executed. By enabling this no-autocommit option, InnoDB can load the data in an efficient way and writes the only one undo log for the whole operation. Only first insert statement undergoes bulk insert operation, remaining insert statement doesn't write undo log and undergoes normal insert code path.
