Expand description

it’s kind of like a PlanVisitor<PlanRef>, but with default behaviour of each rewrite method

Required Methods§

source

fn rewrite_logical_share(&mut self, plan: &LogicalShare) -> PlanRef

When we use the plan rewriter, we need to take care of the share operator, because our plan is a DAG rather than a tree. Make sure this method can keep the shape of DAG.
