Production-grade distributed streaming system with Redis-backed state synchronization and async WebSocket broadcasting
Description
Distributed streaming system with Redis-backed state synchronization and async WebSocket broadcasting.
Problem Solved
Maintaining price continuity across distributed processes (HTTP server for historical data, WebSocket server for live streaming) without state divergence. The challenge was implementing zombie-safe WebSocket connection management, exponential backoff reconnection, and graceful frontend degradation during backend failures.
Architecture
Distributed stateful streaming system with shared persistence layer. Redis as single source of truth for price data between HTTP and WebSocket servers. Python AsyncIO for concurrent WebSocket broadcasting. React frontend with custom hooks managing dual-protocol data fetching and auto-reconnection logic.
