   > The benchmark though should add parallelism by repartitioning after scanning - so I would expect aggregates to be executed in parallel (even though the scan won't be).
   
   I recently look at Datafusion vs DuckDB for our use cases and one of query is a variant of ClickBench q23.
   - Datafusion v19.rc1: 12s
   - DuckDB v0.6.1: 0.6s (20x faster)
   
   it aligns with "scan is not in parallel yet"
