**Note**: You can mix `def` and `async def` in your *path operation functions* as much as you need and define each one using the best option for you. FastAPI will do the right thing with them.

Anyway, in any of the cases above, FastAPI will still work asynchronously and be extremely fast.

But by following the steps above, it will be able to do some performance optimizations.

Esta es una funcionalidad "avanzada".

Si apenas estás comenzando con **FastAPI**, quizás quieras saltar esta sección.

## Casos de uso { #use-cases }

Algunos casos de uso incluyen:

* Convertir cuerpos de requests no-JSON a JSON (por ejemplo, <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).

## Future { #future }

By this point, it's already clear that **FastAPI** with its ideas is being useful for many people.

It is being chosen over previous alternatives for suiting many use cases better.

Many developers and teams already depend on **FastAPI** for their projects (including me and my team).

But still, there are many improvements and features to come.

**FastAPI** has a great future ahead.
