I think the more general flow here is to take a predicate like `c2 = lit` and a schema of `c1`, `c3` and replace `c2` with `NULL` -- which is what the code changed in https://github.com/apache/arrow-datafusion/pull/3470 is. Then the predicate is `NULL = lit` which can be reduced to `false` if we run the constant evaluator on it -- This is an automated message from the Apache Git Service.
