// Package parquet provides an implementation of Apache Parquet for Go.
//
// Apache Parquet is an open-source columnar data storage format using the record
// shredding and assembly algorithm to accommodate complex data structures which
// can then be used to efficiently store the data.
//
// This implementation is a native go implementation for reading and writing the
// parquet file format.
//
// Install
//
// You can download the library and cli utilities via:
//   go get -u github.com/apache/arrow/go/v10/parquet
//   go install github.com/apache/arrow/go/v10/parquet/cmd/parquet_reader@latest
//   go install github.com/apache/arrow/go/v10/parquet/cmd/parquet_schema@latest
//
// Modules
//
// This top level parquet package contains the basic common types and reader/writer
// properties along with some utilities that are used throughout the other modules.
//
// The file module contains the functions for directly reading/writing parquet files
// including Column Readers and Column Writers.
//
// The metadata module contains the types for managing the lower level file/rowgroup/column
// metadata inside of a ParquetFile including inspecting the statistics.
//
// The pqarrow module contains helper functions and types for converting directly
// between Parquet and Apache Arrow formats.
//
// The schema module contains the types for manipulating / inspecting / creating
// parquet file schemas.
//
// Primitive Types
//
// The Parquet Primitive Types and their corresponding Go types are Boolean (bool),
// Int32 (int32), Int64 (int64), Int96 (parquet.Int96), Float (float32), Double (float64),
// ByteArray (parquet.ByteArray) and FixedLenByteArray (parquet.FixedLenByteArray).
//
// Encodings
//
// The encoding types supported in this package are:
// Plain, Plain/RLE Dictionary, Delta Binary Packed (only integer types), Delta Byte Array
// (only ByteArray), Delta Length Byte Array (only ByteArray)
//
// Tip: Some platforms don't necessarily support all kinds of encodings. If you're not
// sure what to use, just use Plain and Dictionary encoding.
