org.apache.parquet.format.NullType

All Implemented Interfaces:

Serializable, Cloneable, Comparable<NullType>, org.apache.thrift.TBase<NullType,NullType._Fields>, org.apache.thrift.TSerializable

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.
