ExecSubqueryExpression Expressions

SubqueryExpression is an extension of the PlanExpression abstraction for subquery expressions with BaseSubqueryExec physical operators (for a subquery).

Contract

updateResult

updateResult(): Unit

Updates the expression with a collected result from an executed plan

updateResult is used when SparkPlan is requested to waitForSubqueries.

withNewPlan

withNewPlan(
  plan: BaseSubqueryExec): ExecSubqueryExpression

Note

withNewPlan is part of the PlanExpression abstraction and is defined as follows:

withNewPlan(plan: T): PlanExpression[T]

The purpose of this override method is to change the input and output generic types to the concrete BaseSubqueryExec and ExecSubqueryExpression, respectively.
