Keynote: Overview of gRPC
summary
gRPC uses Protocol Buffers for compact binary messages and HTTP/2 for multiplexed streams with HPACK header compression, claiming industry‑leading latency and reduced payloads; it generates native stubs for 10+ languages, supports four communication flavors (unary, server/client streaming, bidirectional), and runs asynchronous RPCs over long‑lived channels (do not create per request). Name resolution is pluggable, client‑side load balancing and service config control retries and timeouts, deadlines propagate downstream, and shutdown offers draining versus abortive termination.
