Thanks for the thorough thoughts/info @adriangb! I'm wondering if there are effectively multiple optimizations that we can take advantage of here. I think building an `IN LIST` in the dynamic filter (in addition to min/max) allows us to leverage the existing machinery that builds literal guarantees in `PruningPredicate`. The parquet data source already takes advantage of this in the case that bloom filters are present and can help us prune entire row groups, which definitely seems valuable to me. Additionally, your point around building a bloom filter to pushdown as another `PhysicalExpr` also makes a lot of sense to me. Since this would (likely) let us save on more decode cycles. Does that sound right to you? -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
