Review Comment:
Yes, you are right. Speaking of this idea, I also want to mention that we
have tried to replace the pruning logic in PruningPredicate with this interval
library but realized that it disrupts the vectorized calculations. So I'm
thinking about how we can use it without breaking the vectorized process.
