# Extra Data Types

Up to now, you have been using common data types, like:

* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

## Other data types

   * code would be responsible for populating a "real" {@code T} (which might still be the value
   * {@code null}!) before returning it to callers. Depending on how the code is structured, a

Alternatively, we could send the GOAWAY prior to the pod termination (assuming this allows existing and new connections to function still).

## Ztunnel Shutdown/Upgrade/Restart

This could be upgrading to a new version, or changing some part of the DaemonSet spec, etc.

Even if your **FastAPI** application uses normal `def` functions instead of `async def`, it is still an `async` application underneath.
