2. 100% Compatible with proto2 definition and wire protocol
3. Zero-copy deserialization using Netty ByteBuf
4. Deserialize from direct memory
5. Zero heap allocations in serialization / deserialization
6. Lazy deserialization of strings and bytes
7. Reusable mutable objects
8. No runtime dependency library
9. Java based code generator with Maven plugin
