In #962 I am considering the possibility to make the statistics part of the `ExecutionPlan` trait (and remove them from `TableProvider`). But I think that not all nodes will have a cached version of the statistics, only those nodes for which it is an expensive operation to fetch them and that know that the they will not change. We will probably not need the statistics on the executor, because I doubt that any re-optimization will take place there. So it might be an optimization further down the road to optionally leave them out of the serialization in that case. -- This is an automated message from the Apache Git Service.
