Hi everyone, I would like to discuss the table insertion behavior of Spark. In the current data source V2, only UpCast is allowed for table insertion. I think following ANSI SQL is a better idea. For more information, please read the Discuss: Follow ANSI SQL on table insertion <https://docs.google.com/document/d/1b9nnWWbKVDRp7lpzhQS1buv1_lDzWIZY2ApFs5rBcGI/edit?usp=sharing> Please let me know if you have any thoughts on this.
Regards, Gengliang
