cloud-fan commented on issue #23731: [SPARK-26572][SQL] fix aggregate codegen result evaluation URL: https://github.com/apache/spark/pull/23731#issuecomment-462598077 @mgaido91 are you sure aggregate is the only one that produces unevaluated result expressions? IIRC this is a long-standing optimization in the whole stage codegen framework, and there is no such a rule that operators must evaluate the result expressions before calling `parent.consume`. also cc @rednaxelafx @kiszk
