Required Methods

fn plan_relation( &self, relation: TableFactor, context: &mut dyn RelationPlannerContext, ) -> Result<RelationPlanning>

Returning RelationPlanning::Planned short-circuits further planning and uses the provided plan. Returning RelationPlanning::Original allows the next registered planner, or DataFusion’s default logic, to handle the relation.
