The `NullPropagation` applies to all expressions, but `ReplaceNullWithFalseInPredicate` changes only `Filter`, `Join` and some others. So if I would write the results of `Not(1 IN (1, NULL))` to file, then this rule would change it from `false` to `null`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
