   @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.
