QueryProperties. A structure to contain features of a query that are determined during parsing and may be useful for categorizing a query type These inlucde whether the query contains: a join clause, a group by clause, an order by clause, a sort by clause, a group by clause following a join clause, and whether the query uses a script for mapping/reducing
