cloud-fan commented on issue #24223: [SPARK-27278][SQL] Optimize GetMapValue when the map is a foldable and the key is not URL: https://github.com/apache/spark/pull/24223#issuecomment-479566209 "increase the code size" -> "increase the generated java code size, which may cause perf regression" Yea I think it's better to revert it first. We can revisit it when we adding official "loop unrolling" support for array/map operations.
