 * output for those input batch correctly. In this case it receives first non-empty batch with OK_NEW_SCHEMA in
 * buildSchema phase followed by an empty batch with EMIT outcome. For this combination it produces output for the
 * record received so far along with EMIT outcome. Then it receives second non-empty batch with OK outcome and
