Partial Aggregate Showplan Operator

  • Artigo

Partial Aggregate is used in parallel plans. It applies an aggregation function to as many input rows as possible so that writing to disk (known as a "spill") is not necessary. Hash Match is the only physical operator (iterator) that implements partition aggregation. Partial Aggregate is a logical operator.
