Para distinguir os modelos com todos os valores opcionais para **atualizações** e modelos com valores obrigatórios para **criação**, você pode usar as ideias descritas em [Modelos Adicionais](extra-models.md){.internal-link target=_blank}.

Additional optional FastAPI dependencies:

Extra metadata maintained internally in `xl.meta` for a transitioned object

In this case, it would be better to get **one extra server** and run some processes on it so that they all have **enough RAM and CPU time**.

There's also the chance that for some reason you have a **spike** of usage of your API. Maybe it went viral, or maybe some other services or bots start using it. And you might want to have extra resources to be safe in those cases.

Nesse exemplo, as *operações de rota* sob o `router` irão usar a classe `TimedRoute` personalizada, e terão um cabeçalho extra `X-Response-Time` na resposta com o tempo que levou para gerar a resposta:

We are not verifying the validity of the token yet, but that's a start already.
