Class Summary

Class	Description
ColumnOrder	Class representing the column order with all the related parameters.
ConversionPatterns	Utility functions to convert from Java-like map and list types to equivalent Parquet types.
DecimalMetadata	Deprecated. use LogicalTypeAnnotation.DecimalLogicalTypeAnnotation with proper precision and scale parameters instead
GroupType	Represents a group type: a list of fields
LogicalTypeAnnotation
LogicalTypeAnnotation.BsonLogicalTypeAnnotation
LogicalTypeAnnotation.DateLogicalTypeAnnotation
LogicalTypeAnnotation.DecimalLogicalTypeAnnotation
LogicalTypeAnnotation.EnumLogicalTypeAnnotation
LogicalTypeAnnotation.IntervalLogicalTypeAnnotation

LogicalTypeAnnotation.UUIDLogicalTypeAnnotation
MessageType	The root of a schema
MessageTypeParser	Parses a schema from a textual format similar to that described in the Dremel paper.
PrimitiveComparator<T>	Comparator implementation that also supports the comparison of the related primitive type to avoid the performance penalty of boxing/unboxing.
PrimitiveStringifier	Class that provides string representations for the primitive values.
PrimitiveType	Representation of a Primitive type
Type	Represents the declared type for a field in a schema.
Type.ID	represents a field ID
Types	This class provides fluent builders that produce Parquet schema Types.
