dongjoon-hyun edited a comment on issue #24593: [SPARK-27692][SQL] Add new optimizer rule to evaluate the deterministic scala udf only once if all inputs are literals URL: https://github.com/apache/spark/pull/24593#issuecomment-493704947 Since SPARK-27761 is created, can we reduce the focus back to the optimizer again? Actually, `override def foldable` will be the simplest code changes, but if we need to provide this optionally, a separate optimizer proposed in this PR will be the most feasible approach (without touching `ScalaUDF` and the existing optimizers like `ConstantFolding`.)
