Protobuf

Protobuf (Protocol Buffers) is Google's language-agnostic, platform-neutral, extensible mechanism for serializing structured data.

Protobuf, or Protocol Buffers, offers a robust, efficient solution for data serialization. Developed by Google, it allows developers to define data structures once (in a `.proto` file) and then generate source code in various languages (e.g., Java, C++, Python, Go) to easily write and read that structured data. This approach ensures backward compatibility and significantly reduces message sizes compared to alternatives like XML or JSON, making it ideal for high-performance communication in microservices, API interactions, and data storage. Its strong typing and schema enforcement prevent common runtime errors, streamlining development and deployment across diverse systems.
