Common Usage

gRPC is a high-performance RPC framework that uses HTTP/2 for transport and Protocol Buffers for serialization. It is used for microservice communication, real-time streaming, mobile backends, and polyglot systems.

gRPC supports unary, server streaming, client streaming, and bidirectional streaming.
