> 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" More detail here: https://github.com/apache/arrow-datafusion/issues/5404 -- This is an automated message from the Apache Git Service.
