   Today I do benchmark for DuckDB(C++) and Polars(Rust) using Parquet and CSV. 
   The performance of DuckDB to Filter and GroupBy a parquet file which contain 300 Million Rows, is only 3.9s.

   So I consider to use DuckDB directly as my Peaks parquet calc engine as I am unlikely can faster than 3.9s.
