The "Protocol Buffers Handbook" by Clément Jean offers an in-depth exploration of Protocol Buffers (Protobuf), a powerful data serialization format. Learn everything from syntax and schema evolution to custom validations and cross-language integrations. With practical examples in Go and Python, this guide empowers you to efficiently serialize and manage structured data across platforms. What this Book will help me do Develop advanced skills in using Protocol Buffers (Protobuf) for efficient data serialization. Master the key concepts of Protobuf syntax and schema evolution for compatibility. Learn to create custom validation plugins and tailor Protobuf processes. Integrate Protobuf with multiple programming environments, including Go and Python. Automate Protobuf projects using tools like Buf and Bazel to streamline workflows. Author(s) Clément Jean is a skilled programmer and technical writer specializing in data serialization and distributed systems. With substantial experience in developing scalable microservices, he shares valuable insights into using Protocol Buffers effectively. Through this book, Clément offers a hands-on approach to Protobuf, blending theory with practical examples derived from real-world scenarios. Who is it for? This book is perfect for software engineers, system integrators, and data architects who aim to optimize data serialization and APIs, regardless of their programming language expertise. Beginners will grasp foundational Protobuf concepts, while experienced developers will extend their knowledge to advanced, practical applications. Those working with microservices and heavily data-dependent systems will find this book especially relevant.
