Protocol Buffers Handbook

By: Clément Jean

Overview of this book

Explore how Protocol Buffers (Protobuf) serialize structured data and provides a language-neutral, platform-neutral, and extensible solution. With this guide to mastering Protobuf, you'll build your skills to effectively serialize, transmit, and manage data across diverse platforms and languages. This book will help you enter the world of Protocol Buffers by unraveling the intricate nuances of Protobuf syntax and showing you how to define complex data structures. As you progress, you’ll learn schema evolution, ensuring seamless compatibility as your projects evolve. The book also covers advanced topics such as custom options and plugins, allowing you to tailor validation processes to your specific requirements. You’ll understand how to automate project builds using cutting-edge tools such as Buf and Bazel, streamlining your development workflow. With hands-on projects in Go and Python programming, you’ll learn how to practically apply Protobuf concepts. Later chapters will show you how to integrate data interchange capabilities across different programming languages, enabling efficient collaboration and system interoperability. By the end of this book, you’ll have a solid understanding of Protobuf internals, enabling you to discern when and how to use and redefine your approach to data serialization.

Describing Data with Protobuf Text Format

Before moving towards learning the internals of Protobuf, there is another skill that we need to learn. This skill is reading and writing txtpb files. They contain data written in the Protobuf text format, which is the text representation of the data that we deserialize from the binary form or the data that we want to serialize into binary form.

In this chapter, we’re going to cover the following main topics:

  • Why use the text format
  • Writing scalar values
  • Writing complex types

At the end of this chapter, you will know what the Protobuf text format is and what it is used for. However, most importantly, you will be able to write data that we will later use to discover the internals of serialization and deserialization.
