Another point is that we should ensure that the input schema matches table's schema, otherwise we are doing schema evolution during write.

Columns nullability and field type would be checked within execute_input_stream when it's binding the Iceberg table schema to the input RecordBatch. So we don't need to worry about it now.
This may prevent us from doing any forms of schema evolution, but I think that's a separate issue
