* The alpha Accelerators feature gate is deprecated and will be removed in v1.11. Please use device plugins ([https://github.com/kubernetes/enhancements/issues/368](https://github.com/kubernetes/enhancements/issues/368)) instead. They can be enabled using the DevicePlugins feature gate. ([#57384](https://github.com/kubernetes/kubernetes/pull/57384), [@mindprince](https://github.com/mindprince))

## Known Issues

### `TopologyAwareHints` feature falls back to default behavior

  - The GA `PodPriority` feature gate is now on by default and cannot be disabled. The feature gate will be removed in v1.18. ([#79262](https://github.com/kubernetes/kubernetes/pull/79262), [@draveness](https://github.com/draveness))

This idea of **asynchronous** code described above is also sometimes called **"concurrency"**. It is different from **"parallelism"**.

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

* CRI logging and stats are now considered beta ([ref](https://github.com/kubernetes/enhancements/issues/552))
* The dynamic Kubelet config feature is now beta, and the DynamicKubeletConfig feature gate is on by default. In order to use dynamic Kubelet config, ensure that the Kubelet's --dynamic-config-dir option is set.  ([#64275](https://github.com/kubernetes/kubernetes/pull/64275), [@mtaufen](https://github.com/mtaufen))

* Use of the alpha initializers feature now requires enabling the `Initializers` feature gate. This feature gate is automatically enabled if the `Initializers` admission plugin is enabled.([#51436](https://github.com/kubernetes/kubernetes/pull/51436))

* Use of the alpha initializers feature now requires enabling the `Initializers` feature gate. This feature gate is auto-enabled if the `Initialzers` admission plugin is enabled. ([#51436](https://github.com/kubernetes/kubernetes/pull/51436), [@liggitt](https://github.com/liggitt))

- The GCERegionalPersistentDisk feature gate (GA in 1.13) can no longer be disabled. The feature gate will be removed in v1.17. ([#77412](https://github.com/kubernetes/kubernetes/pull/77412), [@liggitt](https://github.com/liggitt))

- Volume dynamic provisioning scheduling has been moved to beta, which means that the DynamicProvisioningScheduling alpha feature gate has been removed but the VolumeScheduling beta feature gate is still required for this feature.

Au final, dans les deux situations, il est fort probable que **FastAPI** soit tout de même [plus rapide](index.md#performance){.internal-link target=_blank} que (ou au moins de vitesse égale à) votre framework précédent.

### Dépendances

La même chose s'applique aux dépendances. Si une dépendance est définie avec `def` plutôt que `async def`, elle est exécutée dans la threadpool externe.
