//  - Type: Data type for this field. Not set if the current element is a non-leaf node
//  - TypeLength: If type is FIXED_LEN_BYTE_ARRAY, this is the byte length of the vales.
// Otherwise, if specified, this is the maximum bit length to store any of the values.

//  - RepetitionType: repetition of the field. The root of the schema does not have a repetition_type.
// All other nodes must have one
//  - Name: Name of the field in the schema
//  - NumChildren: Nested fields.  Since thrift does not support nested fields,
// the nesting is flattened to a single list by a depth-first traversal.
// The children count is used to construct the nested relationship.
// This field is not set when the element is a primitive type
//  - ConvertedType: When the schema is the result of a conversion from another model
// Used to record the original type to help with cross conversion.
//  - Scale: Used when this column contains decimal data.
// See the DECIMAL converted type for more details.
//  - Precision

// Union to specify the order used for the min_value and max_value fields for a
// column. This union takes the role of an enhanced enum that allows rich

//
// Possible values are:
// * TypeDefinedOrder - the column uses the order defined by its logical or
//                      physical type (if there is no logical type).
//
// If the reader does not support the value of this union, min and max stats
// for this column should be ignored.
//
// Attributes:
//  - TYPE_ORDER: The sort orders for logical types are:
//   UTF8 - unsigned byte-wise comparison
//   INT8 - signed comparison
//   INT16 - signed comparison
//   INT32 - signed comparison
//   INT64 - signed comparison
//   UINT8 - unsigned comparison
//   UINT16 - unsigned comparison
//   UINT32 - unsigned comparison
//   UINT64 - unsigned comparison
//   DECIMAL - signed comparison of the represented value
//   DATE - signed comparison
//   TIME_MILLIS - signed comparison
//   TIME_MICROS - signed comparison
//   TIMESTAMP_MILLIS - signed comparison
//   TIMESTAMP_MICROS - signed comparison
//   INTERVAL - unsigned comparison
//   JSON - unsigned byte-wise comparison
//   BSON - unsigned byte-wise comparison
//   ENUM - unsigned byte-wise comparison
//   LIST - undefined
//   MAP - undefined
//
// In the absence of logical types, the sort order is determined by the physical type:
//   BOOLEAN - false, true
//   INT32 - signed comparison
//   INT64 - signed comparison
//   INT96 (only used for legacy timestamps) - undefined
//   FLOAT - signed comparison of the represented value (*)
//   DOUBLE - signed comparison of the represented value (*)
//   BYTE_ARRAY - unsigned byte-wise comparison
//   FIXED_LEN_BYTE_ARRAY - unsigned byte-wise comparison
//
// (*) Because the sorting order is not specified properly for floating
//     point values (relations vs. total ordering) the following
//     compatibility rules should be applied when reading statistics:
//     - If the min is a NaN, it should be ignored.
//     - If the max is a NaN, it should be ignored.
//     - If the min is +0, the row group may contain -0 values as well.
//     - If the max is -0, the row group may contain +0 values as well.
//     - When looking for NaN values, min and max should be ignored.

// Each <array-field>[i] refers to the page at OffsetIndex.page_locations[i]
//
// Attributes:
//  - NullPages: A list of Boolean values to determine the validity of the corresponding
// min and max values. If true, a page contains only null values, and writers
// have to set the corresponding entries in min_values and max_values to
// byte[0], so that all lists have the same length. If false, the
// corresponding entries in min_values and max_values must be valid.
//  - MinValues: Two lists containing lower and upper bounds for the values of each page.
// These may be the actual minimum and maximum values found on a page, but
// can also be (more compact) values that do not exist on a page. For
// example, instead of storing ""Blart Versenwald III", a writer may set
// min_values[i]="B", max_values[i]="C". Such more compact values must still
// be valid values within the column's logical type. Readers must make sure
// that list entries are populated before using them by inspecting null_pages.
//  - MaxValues
//  - BoundaryOrder: Stores whether both min_values and max_values are orderd and if so, in
// which direction. This allows readers to perform binary searches in both
// lists. Readers cannot assume that max_values[i] <= min_values[i+1], even
// if the lists are ordered.
//  - NullCounts: A list containing the number of null values for each page *

// are flattened to a list by doing a depth-first traversal.
// The column metadata contains the path in the schema for that column which can be
// used to map columns to nodes in the schema.
// The first element is the root *
//  - NumRows: Number of rows in this file *
//  - RowGroups: Row groups in this file *
//  - KeyValueMetadata: Optional key/value metadata *
//  - CreatedBy: String for application that wrote this file.  This should be in the format
// <Application> version <App Version> (build <App Build Hash>).
// e.g. impala version 1.0 (build 6cf94d29b2b7115df4de2c06e2ab4326d721eb55)

// this file. Each sort order corresponds to one column, determined by its
// position in the list, matching the position of the column in the schema.
//
// Without column_orders, the meaning of the min_value and max_value fields is
// undefined. To ensure well-defined behaviour, if min_value and max_value are
// written to a Parquet file, column_orders must be written as well.
