@rdettai got it, thanks. Im still just working on getting an understanding of the existing rules. Would you be able to provide some more details on why there is a `lit_expr` for the count rule and its equal to `&ScalarValue::UInt8(Some(1))`? My naive expectation was to have something similar to the max_min where a `col_expr` was made and the `num_rows` / `null_count` from the `ColumnStatistics` could be used. thx in advance. -- This is an automated message from the Apache Git Service.
