Protocol Buffers, commonly known as protobufs are a free and open-source cross-platform data format used to serialize structured data. It helps develop programs to communicate with each other over a network or store data. Think of formats such as XML, JSON, Pickle, etc.
Protocol Buffers, however, are much faster and provide a much more compact data storage; they are optimized via automatically generated classes for a wide range of programming languages.
You often encounter protocol buffers when working with tools such as gRPC. They are also used internally by Google cloud and other applications.
