public static class QueryPlan.NonCorrelatedAnyAllNode extends QueryPlan.BranchQueryPlanNode
A branch node for a non-correlated ANY or ALL sub-query evaluation. This node requires a set of columns from the left branch and an operator. The right branch represents the non-correlated sub-query.

NOTE: The cost of a SubQuery is higher if the right child result is greater than the left child result. The plan should be arranged so smaller results are on the left.
