SSE is commonly used for AI chat streaming, live notifications, logs and observability, and other cases where the server pushes updates to the client.

## Stream SSE with FastAPI { #stream-sse-with-fastapi }

You could use this to stream data from an **AI LLM** service, from **logs** or **telemetry**, or from other types of data that can be structured in **JSON** items.

También podrías usarlo para transmitir archivos binarios grandes, donde transmites cada bloque de datos a medida que lo lees, sin tener que leerlo todo en memoria de una sola vez.

También podrías transmitir video o audio de esta manera; incluso podría generarse mientras lo procesas y lo envías.

## Un `StreamingResponse` con `yield` { #a-streamingresponse-with-yield }

Sie könnten es auch nutzen, um **große Binärdateien** zu streamen, wobei Sie jeden Datenchunk beim Lesen streamen, ohne alles auf einmal in den Speicher laden zu müssen.

Sie könnten auf diese Weise auch **Video** oder **Audio** streamen, es könnte sogar beim Verarbeiten erzeugt und gesendet werden.

			traceFn := globalLifecycleSys.trace(oi)
			tags := newLifecycleAuditEvent(lcEventSrc_Scanner, lcEvent[i]).Tags()

			// Send audit for the lifecycle delete operation
			auditLogLifecycle(
				ctx,
				oi,
				ILMExpiry, tags, traceFn)

			evArgs := eventArgs{
				EventName:  event.ObjectRemovedDelete,
				BucketName: bucket,

Você também pode usá-lo para transmitir arquivos binários grandes, enviando cada bloco de dados à medida que o lê, sem precisar carregar tudo na memória de uma vez.

Você também pode transmitir vídeo ou áudio desta forma; pode até ser gerado enquanto você processa e envia.

	// to send an appropriate audit log.

You could also use it to stream **large binary files**, where you stream each chunk of data as you read it, without having to read it all in memory at once.

You could also stream **video** or **audio** this way, it could even be generated as you process and send it.
