For very fast communication between different parts of a large system, what kind of data structure helps gRPC be super efficient and work with many programming languages?

The data structure that helps gRPC achieve super-efficient, multi-language communication is Protocol Buffers, commonly known as Protobuf. Protocol Buffers are a language-neutral, platform-neutral, extensible mechanism for serializing structured data. For efficiency, Protocol Buffers serialize data into a compact binary format. This binary serialization means the data transmitted over the network is significantly smaller than text-based formats l....
