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 |

SSE, WebSockets 및 ReadableStream을 통한 실시간 데이터 스트리밍. 스트리밍 응답, 실시간 데이터 업데이트, 서버 전송 이벤트, WebSocket 설정, 실시간 알림, 푸시 업데이트 또는 채팅 서버 백엔드를 구현할 때 사용합니다. 출처: yonatangross/orchestkit.
