If we do not allow anyone modify config:: doris_scanner_row_num, I think it should be a const expr variable not in config file. If it is in conf file, then it maybe modified by someone, so that we should check it. And also, maybe nobody will modify doris_scanner_row_num, but somebody could modify batch size, the batch size maybe larger than the config::doris_scanner_row_num. -- This is an automated message from the Apache Git Service.
