> > 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. > > I think passing the hash table or directly an IN LIST predicate would also help users with custom `ExecutionPlan` scan nodes that aren’t Parquet or don’t support bloom predicates. Any of these ideas (IN LIST, reference to the hash table, a bloom filter) would be packaged up behind a PhysicalExpr so they should all be supported in the same way. -- This is an automated message from the Apache Git Service.
