summary
Company moves HELLO 2 to microservices and builds a WebSocket hub that handles real-time TCP full‑duplex sessions; implementation uses per‑connection goroutines and messaging channels and exposes a central hub that routes subscribe/publish events. Encountered surprising failure mode: unsynchronized maps crash under concurrent access, fixed by mutex‑protected maps and encapsulation. Works at scale after rearchitecture — hundreds of simultaneous connections, ping/pong keepalives, reconnection and ack logic added to avoid message loss.
