Hi Mai, Good to see you again!
So far, we haven't performed QphH-based benchmark. Some of original TPC-H benchmark queries may not work in Tajo because scalar subquery, in-subquery, exist-subquery are not supported yet. So, you need to change slightly them into multiple queries. I haven't experienced such a situation you explained, could you share the error log that you met while you were executing multiple queries?
