Por padrão, teremos o **recarregamento automático** ativo, então o programa irá recarregar o servidor automaticamente toda vez que você fizer mudanças no seu código. Isso usa muitos recursos e pode ser menos estável. Você deve apenas usá-lo em modo de desenvolvimento.

O servidor de desenvolvimento escutará no endereço de IP `127.0.0.1` por padrão, este é o IP que sua máquina usa para se comunicar com ela mesma (`localhost`).

    // It really seems like this should be faster than TO_BYTE_ARRAY_NEW_STRING.  But it just isn't
    // my best guess is that the jdk authors have spent more time optimizing that callpath than this
    // one. (StringCoding$StringDecoder vs. StreamDecoder).  StringCoding has a ton of special cases

You can also measure the cumulative time your build agents spent building a changeset, which will give you a sense of the amount of work the CI infrastructure has to exert. The cache's effect here is less money spent on CI resources, as you don't need as many CI agents to maintain the same number of changes built.

Novamente, apenas fazendo essa declaração, com o **FastAPI**, você ganha:

* Suporte do editor de texto (compleção, etc), inclusive para modelos aninhados
* Conversão de dados
* Validação de dados
* Documentação automatica
