Panel: AI's Real-Time Engine: gRPC, WebSockets, or SSE?
summary
Real deployments pick a mix not a single protocol: use gRPC bidirectional streaming for low-latency backend token streams and vector DBs (binary protobuf shrinks payloads vs JSON), use WebSockets for browser-first full‑duplex paths, and consider WebTransport (HTTP/3/QUIC) or MQTT for packet-loss resilience and IoT sensors. Expect gRPC‑Web/transcoding to add ~30–40% CPU overhead, HTTP/2 head‑of‑line blocking to hurt per‑stream latency, and backpressure, connection migration and gateway load‑balancing to decide the final architecture.
