I don't think it's a problem of JDBC v2. It's a problem of the pushdown framework. Distinct aggregate functions have very special planning rule and it's very complicated to do partial pushdown. My suggestion is to only do complete pushdown if there exists distinct aggregate functions, in the pushdown framework. -- This is an automated message from the Apache Git Service.
