Esto será especialmente útil cuando lo uses en una **gran base de código** donde uses **las mismas dependencias** una y otra vez en **muchas *path operations***.

## Usar `async` o no usar `async`

Como las dependencias también serán llamadas por **FastAPI** (lo mismo que tus *path operation functions*), las mismas reglas aplican al definir tus funciones.

Puedes usar `async def` o `def` normal.
