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-446802963 IMHO, given that it's not easy to make chained withColumns works like one projection, we might want to consider exposing `withColumns` to public. If chains are independent, they could be changed to one of `withColumns`, and even some chains depend on others, the depth of projection could be greatly reduced.
