> Add SupportsStatisticsReport and SupportsParallelismReport to dynamic source,
> source can return some information to help table optimizer.
> This information can be more accurate from the source rather than the
> catalog.
> * First, the information is computed base on real data, for iceberg /
> filesystem connector, it can be calculated from real files. Although it is
> related to physical/runtime, it is real and exact.
> * Second, For example, for iceberg / filesystem connector, after filter and
> partition pushdown, the statistics have been greatly adjusted, and many files
> may have been filtered out.
