@atris, Subqueries can broadly be divided into two categories - inner query (and there could be multiple of these) referring to same table as outer query - inner query (and there could be multiple of these) referring to different tables not necessarily same as outer query. Since the overall query might touch more than 1 table and might require us to consider data movement / exchange operators (as in the case of join), we think it is better to think about both during design. This is the reason why we want to approach them together in the design phase to prevent situation where we go ahead and design, implement one of the two features and later on find ourselves retro-fitting the other one. -- This is an automated message from the Apache Git Service.
