Architecture Patterns To Enable Stateful Communication Over Stateless Serverless Apis

on YouTube ↗28m

" summary

Claim: stateless serverless functions can host long-lived, ordered streams by layering a lightweight session layer and session ID mapped to an in-memory store that holds logs and ordering metadata. Uses HTTP/gRPC/WebSocket transports, Firestore-style watch APIs and push services (Firebase Cloud Messaging) as comparisons; proposes primitives: session creation, durable session store, and a push function that notifies clients. Case study sketches a real-time chat prototype with sub-second latency goals; solution exists as internal infrastructure work, not yet a public, finished product.
