public class LookupPruneFilters
extends PruneFilters

Lookup-specific variant of PruneFilters. When a filter condition evaluates to false and the filter's subtree contains a ParameterizedQuery, marks it as emptyResult=true instead of collapsing the entire plan to a LocalRelation. This preserves the plan structure so the LookupExecutionPlanner can still build the operator chain.

Method Details

handleAlwaysFalseFilter

protected LogicalPlan handleAlwaysFalseFilter(Filter filter)

Description copied from class: PruneFilters

Handles a filter whose condition has been folded to false or null. By default, collapses the plan via PruneEmptyPlans.skipPlan(org.elasticsearch.xpack.esql.plan.logical.UnaryPlan); subclasses may override to preserve plan structure when collapsing is not appropriate (e.g. lookup plans).
