gRPC trong Go dùng khi nào?

RPC framework dùng Protocol Buffers (protobuf).

• Nhanh hơn REST (binary encoding, HTTP/2).
• Dùng khi: microservices internal communication, streaming (bidirectional), cần type safety chặt.
• Define service trong .proto file → protoc generate Go code.
• Hỗ trợ: unary, server streaming, client streaming, bidirectional.

gRPC is an RPC framework using Protocol Buffers (protobuf).

• It is faster than REST thanks to binary encoding and HTTP/2.
• Use it for: microservice-to-microservice communication, streaming (bidirectional), and when strong type safety is required.
• Define your service in a .proto file → protoc generates Go code.
• Supports: unary, server streaming, client streaming, and bidirectional streaming.
