Protocol Buffers

Explains Protocol Buffers

Jul 15, 2025

A language-neutral, platform-independent, and extensible mechanism for serializing structured data.

It encodes data into a compact binary format, making it efficient for communication.

Like XML, Protobuf defines structured data in a more efficient way. A schema is defined and used by both the client and server to serialize and deserialize the data.

Protobuf also provides a way to extend the schema without breaking backward compatibility.

protobuf syntax
