ScalarSubquery

case class ScalarSubquery(plan: BaseSubqueryExec, exprId: ExprId) extends ExecSubqueryExpression with LeafLike[Expression] with Product with Serializable

A subquery that will return only one row and one column.

This is the physical copy of ScalarSubquery to be used inside SparkPlan.
