Thank you for the review @tustvold |

FYI @XiangpengHao -- these are the structures related to predicate pushdown. As the other docs explain, there are some tradeoffs when evaluating these predicates (among other thing, I think the same columns may be decoded multiple times if there are multiple predicates that refer to them). There may be some optimization opportunity in this area -- if you get to the point where you might use this in your research, please let me know and I can writeup some thoughts on how we could improve things in this area |
