Introduction

This book is part of my parquet learning journey. It shows you how to implement a parquet parser from scratch. The goal of this book is to understand the internals of the parquet file format by actually writing a parser. It does not, however, cover how to to use parquet, or how to query it efficiently.

The book itself is written as a series of exercises; each step contains test cases to verify the implementation. At the end, the parser will be able to read parquet files with primitive types, basic encodings, compression, and nulls.

The parser is written in Rust and readers are expected to implement all the steps themselves to have a working parser.
