gRPC and Go: Developing Efficient and Type-Safe Services
summary
Claims gRPC replaces JSON/REST with protobuf IDL + HTTP/2 binary framing to cut latency and memory. Demo compiles a .proto with protoc into Go stubs, implements a currency-lookup service reading CSV, registers server, and a client dials and prints results; it works end-to-end. Shows server, client and server streaming examples, TLS via credentials APIs, context deadlines for timeouts, structured gRPC error codes. Benchmarks claim JSON RPC took ~8m7s vs gRPC ~36s; allocations down ~23% and memory use ~40% lower.
