@aokolnychyi @cloud-fan @dongjoon-hyun @rdblue Could one of you please review this PR? This change specifically improves[ MERGE INTO](https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/RewriteMergeIntoTable.scala) operations by fusing the Join Operator (typically SortMerge) and the MergeRow operator. This fusion is expected to significantly boost MERGE performance at scale by reducing virtual function call overhead. Furthermore, it enables this path to be code-generated and potentially interoperate with other codegen-supported operators(most operators in Spark) in the future. -- This is an automated message from the Apache Git Service.
