About Protocol Buffers

Protocol Buffers (protobuf) is Google's language-neutral data serialization format:

📜 Schema

.proto files define message structures with typed fields and unique field numbers

⚡ Compact

Binary format is much smaller than JSON/XML - ideal for network communication

🔗 Multi-Language

Generate code for Java, Python, C++, Go, and many other languages

🔄 Wire Format

Field number + wire type + value encoding allows forward/backward compatibility

Encoding and Data Utilities

Encode, decode, measure sizes, and transform common formats.
