viirya commented on issue #23740: [SPARK-26837][SQL] Pruning nested fields from object serializers URL: https://github.com/apache/spark/pull/23740#issuecomment-465132735 > shall we create a new rule to do column pruning for object serializers? And in the `ColumnPrunning` rule we skip `Project(SerializeObject(...))` I'd say it might be a good idea, because the column pruning grows too long. I will do it in next update.
