Method Details

rule

protected LogicalPlan rule(Filter filter)

Specified by:

rule in class OptimizerRules.OptimizerRule<Filter>

handleAlwaysFalseFilter

protected LogicalPlan handleAlwaysFalseFilter(Filter filter)

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).
