I will take a look. Usually, for un-correlated scalar subqueries, it will be kept as the subquery but need to do count check. WHERE EXISTS (SELECT b FROM t2 where a>1 ) rewrite to WHERE EXISTS (SELECT b FROM t2 where a>1 limit 2) We need to add a physical SubQueryExec. -- This is an automated message from the Apache Git Service.
