> The motivation of the FLIP is to further extend the range of operations and expressions that are SQL serializable. Currently, it is not possible to declare a table using CREATE TABLE, creating structured types outside of UDFs, using a CAST, or declaring them as part of a @DataTypeHint function annotation. Table API’s table descriptors support structured types already.
