gengliangwang commented on issue #23829: [SPARK-26915][SQL]File source should write without schema validation in DataFrameWriter.save() URL: https://github.com/apache/spark/pull/23829#issuecomment-464978695 > Even after the catalog support of DS V2 is implemented, I think it is hard to support both behaviors with the current API/framework. That's my major concern. The behavior of `DataFrameWriter.save` is so different from table insertion in traditional databases.
