@Generated(value="Autogenerated by Thrift Compiler (0.23.0)", date="2026-08-06") public class NullType extends Object implements org.apache.thrift.TBase<NullType,NullType._Fields>, Serializable, Cloneable, Comparable<NullType>
Logical type to annotate a column that is always null. Sometimes when discovering the schema of existing data, values are always null and the physical type can't be determined. This annotation signals the case where the physical type was guessed from all null values.
