What is gRPC?

A high-performance RPC framework using Protocol Buffers and HTTP/2 for efficient service-to-service communication.

gRPC (Google Remote Procedure Call) enables services to call methods on other services as if they were local functions. It uses Protocol Buffers for schema definition and binary serialization (smaller and faster than JSON), and HTTP/2 for multiplexed streaming.

gRPC supports unary calls, server/client streaming, and bidirectional streaming. It is ideal for microservices communication, mobile backends, and real-time applications. Language support includes Go, Java, Python, C++, and more.
