How to Build an End-to-End WebRTC Service
summary
Claims reducing call setup from about 10 to 2 seconds by replacing HTTP polling with a push and long‑lived RPC design using gRPC/QUIC bidirectional RPCs and push services (GCM/APNs), and by sharding user state to regional connection servers and local message stores. System builds a rendezvous tickle via push, stores messages in a local DB, marks delivered when handled by the app, and exposes idempotent APIs so clients handle duplicates and out‑of‑order arrivals following at‑least‑once, any‑order delivery semantics.
