- Previously the predicate stayed a `BoundUnaryPredicate`, and since unknown columns have no metrics, `NOT NULL` could not prune any data files. - Values of the v3 `unknown` type are always null, so `IS NULL` on an unknown column now binds to `AlwaysTrue` and `NOT NULL` binds to `AlwaysFalse`. - This resolves the `TODO(gangwu): deal with UnknownType` in `BindUnaryOperation` and matches Java's `UnboundPredicate#bindUnaryOperation`. -- This is an automated message from the Apache Git Service.
