gRPC 101 for Spring Developers
summary
gRPC uses HTTP/2 and protobuf3, generates idiomatic language stubs via protoc, and claims 3x throughput over REST in the demo numbers; Google notes ~10^10 RPCs/sec and ~1 Pabit/sec internal bandwidth as motivation. The demo shows Java code: a proto file → Maven plugin runs protoc → generated async server methods using responseObserver, a blocking and async client channel, and a working server/client/bidirectional streaming chat plus a Spring Boot starter + Eureka proof-of-concept that actually runs and load balances.
