ulysses-you edited a comment on issue #27008: [SPARK-30353][SQL] Add IsNotNull check in SimplifyBinaryComparison optimization URL: https://github.com/apache/spark/pull/27008#issuecomment-569165048 We can make this simply. We just need to check if `IsNotNull` exists. If exists then optimize else not. Constraints is used by `InferFiltersFromConstraints`, we don't need to rely on it strongly. I changed the pr title. cc @maropu @viirya
