  Protocol Buffers (Protobuf) is Google's language-neutral, platform-neutral,
  extensible mechanism for serializing structured data. It defines a schema
  language for specifying message structures in .proto files, which are
  compiled into efficient binary wire format code for multiple programming
  languages. Widely used with gRPC for high-performance remote procedure calls
  and data interchange.
