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). Distinct count might be mostly slow as the current implementation is very allocation-heavy. An additional suggestion to better performance on the benchmark is to add a target-cpu configuration which might yield a ~10% improvement - currently it compiles with the default target. -- This is an automated message from the Apache Git Service.
