### Feature Request / Improvement In spark 4.0 and spark 4.1, we have support to provide how lenient we want the underlying table schema to be and allow evolution of underlying of without changing or updating the view. With Spark SQL we can define it the way mentioned at https://spark.apache.org/docs/latest/sql-ref-syntax-ddl-create-view.html. Currently if the column data type changes and one queries the view without updating the view, one can get UPCAST failed, forcing to do CREATE or REPLACE on the view or forcing to do try_to_cast in the projection. Supporting this, will allow to making the view queries more flexible basis of the definition of the view. ### Query engine Spark ### Willingness to contribute - [ ] I can contribute this improvement/feature independently - [x] I would be willing to contribute this improvement/feature with guidance from the Iceberg community - [ ] I cannot contribute this improvement/feature at this time -- This is an automated message from the Apache Git Service.
