## Casos de uso { #use-cases }

Podrías usar esto para hacer stream de datos desde un servicio de **AI LLM**, desde **logs** o **telemetry**, o desde otros tipos de datos que puedan estructurarse en ítems **JSON**.

/// tip | Consejo

It looks like this:

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

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

/// tip

If you want to stream binary data, for example video or audio, check the advanced guide: [Stream Data](../advanced/stream-data.md).

But normally you won't have to worry about it, it's done automatically, continue reading. 🤓

## Use Cases { #use-cases }

In this case, the client will see an *HTTP 500 Internal Server Error* response as it should, given that we are not raising an `HTTPException` or similar, but the server will **not have any logs** or any other indication of what was the error. 😱

### Always `raise` in Dependencies with `yield` and `except` { #always-raise-in-dependencies-with-yield-and-except }

    // Then, run the actual tests under each alternative classloader:

    runTestMethod(NO_ATOMIC_FIELD_UPDATER);
    // TODO(lukes): assert that the logs are full of errors
  }

  /**
   * Runs the corresponding {@link FuturesTest} test method in a new classloader that disallows
   * certain core JDK classes.

Normalerweise müssen Sie sich darum aber nicht kümmern, das geschieht automatisch, lesen Sie weiter. 🤓
