CRITICAL: Async generators can leak resources if not properly cleaned up. Python 3.10+ provides aclosing() from contextlib to guarantee cleanup.

| External API streaming (LLM, HTTP) | ✅ Always | | Database streaming results | ✅ Always | | File streaming | ✅ Always | | Simple in-memory generators | ⚠️ Optional (no cleanup needed) | | Generator with try/finally cleanup | ✅ Always |

| Server-to-Client Streaming | SSE | Simple protocol, auto-reconnect, HTTP/2 compatible | | Bidirectional Communication | WebSockets | Full-duplex, low latency, binary support | | LLM Token Streaming | ReadableStream + SSE | Backpressure control, standard format | | Reconnection Strategy | Exponential Backoff | Prevents thundering herd, graceful recovery |

Real-time data streaming with SSE, WebSockets, and ReadableStream. Use when implementing streaming responses, real-time data updates, Server-Sent Events, WebSocket setup, live notifications, push updates, or chat server backends. Source: yonatangross/orchestkit.
