Review Comment:
Thanks for your comment!
I actually have thought about this when I wrote the code. The aggregate push
down logic is decided inside `SparkScanBuilder`. I was debating myself if I
should build the aggregates row inside `SparkScanBuilder` or `SparkLocalScan`.
It seems more natural to build the aggregates row in `SparkLocalScan` so I put
it there, but if I move this to `SparkScanBuilder`, then when I build the
aggregates row using statistic, if the statistic are not available, I can fall
back. I will change to that approach.
