Keynote: Overview of gRPC
summary
gRPC uses protobuf over HTTP/2 and emphasizes concrete plumbing: channels create dynamic subchannels, name resolution is pluggable name resolver (schema in target string) and load balancers get service config to manage subchannel lifecycles. Four RPC patterns exist (unary, client/server/bi-directional streaming). Deadlines vs timeouts are propagated and cancelable; retries follow an explicit retry policy with backoff and observability via OpenTelemetry; shutdown lets existing calls finish or be forced closed.
