   Hi @ozankabak , thank you for review, we can propagate source ordering with:
   1. Create external table with order
   2. Create a parquet read with list options to setting the order
   
   But when we write a parquet file with order and the table without order(when 
creating), we can't  propagate the order to the table, we need to write the 
order to parquet metadata.  And when we scan table without sort option setting, 
we can get the metadata for optimization.
   
   For the Statistics to store the info, do you mean we can just load the 
metadata order to somewhere else?
