Se você tiver um objeto semelhante a um arquivo (e.g. o objeto retornado por `open()`), você pode criar uma função geradora para iterar sobre esse objeto.

Dessa forma, você não precisa ler todo o arquivo na memória primeiro, e você pode passar essa função geradora para `StreamingResponse` e retorná-la.

Isso inclui muitas bibliotecas que interagem com armazenamento em nuvem, processamento de vídeos, entre outras.
