Thanks for running the benchmark. The result shows no improvement because the standard TPC-H schema uses Decimal columns, while this PR only decomposes Float64 AVG, so the new optimization is not triggered. In a local release benchmark, I materialized the four Q1 Decimal input columns as Float64 Parquet. Q1 improved from a 29.137 ms median to 25.978 ms, or 10.84%. -- This is an automated message from the Apache Git Service.
