&self,
plan: LogicalPlan,
_config: &dyn OptimizerConfig,
) -> Result<Transformed<LogicalPlan>, DataFusionError>
fn rewrite( &self, plan: LogicalPlan, _config: &dyn OptimizerConfig, ) -> Result<Transformed<LogicalPlan>, DataFusionError>
Try to rewrite
plan to an optimized form, returning Transformed::yes
if the plan was rewritten and Transformed::no if it was not.Source§fn apply_order(&self) -> Option<ApplyOrder>

How should the rule be applied by the optimizer? See comments on
ApplyOrder for details. Read moreSource§fn supports_rewrite(&self) -> bool

👎Deprecated since 47.0.0: This method is no longer used
Does this rule support rewriting owned plans (rather than by reference)?
