**FastAPI** est basé entièrement sur **Pydantic**.

Vous verrez bien plus d'exemples de son utilisation dans [Tutoriel - Guide utilisateur](tutorial/index.md){.internal-link target=_blank}.

## Les annotations de type dans **FastAPI**

**FastAPI** utilise ces annotations pour faire différentes choses.

### Bug or Regression

- Fix scoring for NodeResourcesMostAllocated and NodeResourcesBalancedAllocation plugins when nodes have containers with no requests. This was leaving to under-utilization of small nodes. ([#102925](https://github.com/kubernetes/kubernetes/pull/102925), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

pod priority and pod preemption. These features allow mixing various types of workloads in a single cluster, and help reach
higher levels of resource utilization and availability.
These features are in alpha. SIG Scheduling also improved the internal APIs for scheduling and made them easier for other components and external schedulers to use.

* kubelet: resolved hang/timeout issues when running large numbers of pods with unique configmap/secret references ([#74755](https://github.com/kubernetes/kubernetes/pull/74755), [@liggitt](https://github.com/liggitt))
* Reduce memory utilization of admission webhook metrics by removing resource related labels. ([#69895](https://github.com/kubernetes/kubernetes/pull/69895), [@jpbetz](https://github.com/jpbetz))

Cette combinaison de Flask, Flask-apispec avec Marshmallow et Webargs était ma stack backend préférée jusqu'à la création de **FastAPI**.

Son utilisation a conduit à la création de plusieurs générateurs Flask full-stack. Ce sont les principales stacks que
j'ai (ainsi que plusieurs équipes externes) utilisées jusqu'à présent :

    Detection using Deep Neural Networks.
*   New (experimental)
    [Java API](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/java).
*   Add new Android image stylization demo based on "A Learned Representation
    For Artistic Style", and add YOLO object detector support.
