With CSI the Kubernetes volume layer becomes truly extensible, allowing third party storage developers to write drivers making their storage systems available in Kubernetes without having to touch the core code.

CSI was first introduction as alpha in Kubernetes v1.9 and moved to beta in Kubernetes v1.10.

You can find a list of sample and production drivers in the [CSI Documentation](https://kubernetes.io/docs/concepts/storage/volumes/#csi).

- Introduced support for handling pod failures with respect to the configured pod failure policy rules. ([#111113](https://github.com/kubernetes/kubernetes/pull/111113), [@mimowo](https://github.com/mimowo))
- Introduction of the `DisruptionTarget` pod condition type. Its `reason` field indicates the reason for pod termination:
  - PreemptionByKubeScheduler (Pod preempted by kube-scheduler)

540ef13ed80de325e1a7267/content/en/docs/tasks/administer-cluster/topology-manager.md) enables NUMA alignment of CPU and devices (such as SR-IOV VFs) that will allow your workload to run in an environment optimized for low-latency. Prior to the introduction of the Topology Manager, the CPU and Device Manager would make resource allocation decisions independent of each other. This could result in undesirable allocations on multi-socket systems, causing degraded performance on latency critical applications....

# Introducción a Tipos en Python { #python-types-intro }

Python tiene soporte para "anotaciones de tipos" opcionales (también llamadas "type hints").

Estas **"anotaciones de tipos"** o type hints son una sintaxis especial que permite declarar el <dfn title="por ejemplo: str, int, float, bool">tipo</dfn> de una variable.

Al declarar tipos para tus variables, los editores y herramientas te pueden proporcionar un mejor soporte.

///

## Usar `Annotated` en el tipo del parámetro `q` { #use-annotated-in-the-type-for-the-q-parameter }

¿Recuerdas que te dije antes que `Annotated` puede usarse para agregar metadatos a tus parámetros en la [Introducción a Tipos de Python](../python-types.md#type-hints-with-metadata-annotations)?

Ahora es el momento de usarlo con FastAPI. 🚀

Teníamos esta anotación de tipo:

```Python
q: str | None = None
```

# Alternativas, Inspiración y Comparaciones { #alternatives-inspiration-and-comparisons }

Lo que inspiró a **FastAPI**, cómo se compara con las alternativas y lo que aprendió de ellas.

## Introducción { #intro }

**FastAPI** no existiría si no fuera por el trabajo previo de otros.

Se han creado muchas herramientas antes que han ayudado a inspirar su creación.
