Protocol Buffers is Google's language‑neutral, platform‑neutral mechanism for defining structured data and generating efficient binary serialization code. It includes a compiler (protoc) and runtime libraries for many languages.
Use cases
- Serialize structured data to a compact binary format for storage or network transmission
- Define service interfaces and generate client/server stubs for RPC communication
- Share data schemas across heterogeneous systems written in different programming languages
- Version and evolve data models while maintaining backward compatibility
- Implement high‑performance inter‑process communication in microservices
When to choose
- You need a fast, size‑efficient binary format with strong schema support
- Your system spans multiple languages or platforms and requires a common data contract
- You want automatic code generation for message classes and RPC stubs
- Backward and forward compatibility of data formats is a priority
When to avoid
- Human‑readability of data is essential; JSON or YAML may be more appropriate
- You require dynamic schemas that change at runtime without recompilation
- The overhead of a compiled schema is undesirable for very simple scripts
