HeartSaVioR commented on issue #23285: [SPARK-26224][SQL] Avoid creating many project on subsequent calls to withColumn URL: https://github.com/apache/spark/pull/23285#issuecomment-447332984 It sounds good to me if we can provide warn message to guide replacing them with select. IMHO, the real issue is basically end users don't know chaining withColumn does harm on performance of query. Once we can guide it, it would be enough.
