// 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

// 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)
