Architectural Sizing: SSE vs WebSockets

Server-Sent Events operate cleanly over standard HTTP/2 infrastructure, avoiding stateful bidirectional connection overhead and corporate proxy blockage inherent in WebSockets.

02

Asynchronous FastAPI SSE Token Generator

Review this battle-tested Python FastAPI streaming server implementation supporting graceful connection drop handling and Nginx buffer bypass.

03

Sliding Window Memory Persistence via Redis

Implement sliding-window dialogue buffers with automatic 24-hour TTL expiration, token counting safeguards, and recursive context summarization.
