// Represents a element inside a schema definition.
//  - if it is a group (inner node) then type is undefined and num_children is defined
//  - if it is a primitive type (leaf) then type is defined and num_children is undefined
// the nodes are listed in depth first traversal order.
// 
// Attributes:
//  - 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.
// (e.g. a low cardinality INT col could have this set to 3).  Note that this is
// in the schema, and therefore fixed for the entire file.
//  - 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
//  - FieldID: When the original schema supports field ids, this will save the
// original field id in the parquet schema
//  - LogicalType: The logical type of this SchemaElement
// 
// LogicalType replaces ConvertedType, but ConvertedType is still required
// for some logical types to ensure forward-compatibility in format v1.

// Attributes:
//  - Type: the type of the page: indicates which of the *_header fields is set *
//  - UncompressedPageSize: Uncompressed page size in bytes (not including this header) *
//  - CompressedPageSize: Compressed (and potentially encrypted) page size in bytes, not including this header *
//  - Crc: The 32bit CRC for the page, to be be calculated as follows:
// - Using the standard CRC32 algorithm
// - On the data only, i.e. this header should not be included. 'Data'
//   hereby refers to the concatenation of the repetition levels, the
//   definition levels and the column value, in this exact order.
// - On the encoded versions of the repetition levels, definition levels and
//   column values
// - On the compressed versions of the repetition levels, definition levels
//   and column values where possible;
//   - For v1 data pages, the repetition levels, definition levels and column
//     values are always compressed together. If a compression scheme is
//     specified, the CRC shall be calculated on the compressed version of
//     this concatenation. If no compression scheme is specified, the CRC
//     shall be calculated on the uncompressed version of this concatenation.
//   - For v2 data pages, the repetition levels and definition levels are
//     handled separately from the data and are never compressed (only
//     encoded). If a compression scheme is specified, the CRC shall be
//     calculated on the concatenation of the uncompressed repetition levels,
//     uncompressed definition levels and the compressed column values.
//     If no compression scheme is specified, the CRC shall be calculated on
//     the uncompressed concatenation.
// If enabled, this allows for disabling checksumming in HDFS if only a few
// pages need to be read.

// Description for column metadata
// 
// Attributes:
//  - Type: Type of this column *
//  - Encodings: Set of all encodings used for this column. The purpose is to validate
// whether we can decode those pages. *
//  - PathInSchema: Path in schema *
//  - Codec: Compression codec *
//  - NumValues: Number of values in this column *
//  - TotalUncompressedSize: total byte size of all uncompressed pages in this column chunk (including the headers) *
//  - TotalCompressedSize: total byte size of all compressed, and potentially encrypted, pages
// in this column chunk (including the headers) *
//  - KeyValueMetadata: Optional key/value metadata *
//  - DataPageOffset: Byte offset from beginning of file to first data page *
//  - IndexPageOffset: Byte offset from beginning of file to root index page *
//  - DictionaryPageOffset: Byte offset from the beginning of file to first (only) dictionary page *
//  - Statistics: optional statistics for this column chunk
//  - EncodingStats: Set of all encodings used for pages in this column chunk.
// This information can be used to determine if all data pages are
// dictionary encoded for example *
//  - BloomFilterOffset: Byte offset from beginning of file to Bloom filter data. *

// Union to specify the order used for the min_value and max_value fields for a

// * 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.

// 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.

//  - BoundaryOrder: Stores whether both min_values and max_values are ordered and if so, in

// if the lists are ordered.

// Description for file metadata
// 
// Attributes:
//  - Version: Version of this file *
//  - Schema: Parquet schema for this file.  This schema contains metadata for all the columns.
// The schema is represented as a tree with a single root.  The nodes of the tree
// 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)
// 
//  - ColumnOrders: Sort order used for the min_value and max_value fields of each column in
// this file. Sort orders are listed in the order matching the columns in the
// schema. The indexes are not necessary the same though, because only leaf
// nodes of the schema are represented in the list of sort orders.
// 
// 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.
// 
// The obsolete min and max fields are always sorted by signed comparison
// regardless of column_orders.
//  - EncryptionAlgorithm: Encryption algorithm. This field is set only in encrypted files
// with plaintext footer. Files with encrypted footer store algorithm id
// in FileCryptoMetaData structure.
//  - FooterSigningKeyMetadata: Retrieval metadata of key used for signing the footer.
// Used only in encrypted files with plaintext footer.
