@rdblue Really thank you for your answer!
@viirya @yhuai I think the enhancement by this PR does not bring the extra
penalty that caused by row-level filtering. To confirm it, could @viirya do one
more test scenario, as described below?
Enable filter push down and vectorized read at the same time, but the
filters are unable to prune any row group. We can compare the original
implementation with the new one. The expected result is no performance
difference.
