   Hi @alexeykudinkin , now i am using dataskipping with column stat and meta table enabled, it works to prune files by this feature, but i find the num of matched lines are diff from file based meta.
   For example, we have 'year, month, day' 3 level partitions and if we query the count(*) by using filters including partition columns and other columns, we find the result is diff.(the num of file based meta is ok, but data skipping is less)
