Um dos principais recursos necessários em sistemas API é "<abbr title="também chamado _ marshalling, conversão">serialização</abbr>" de dados, que é pegar dados do código (Python) e converter eles em alguma coisa que possa ser enviado através da rede. Por exemplo, converter um objeto contendo dados de um banco de dados em um objeto JSON. Converter objetos `datetime` em strings etc.

Muchos, muchos usuarios, pero tu servidor está esperando 🕙 su conexión no tan buena para enviar sus requests.

Y luego esperar 🕙 nuevamente a que los responses retornen.

Esta "espera" 🕙 se mide en microsegundos, pero aún así, sumándolo todo, es mucha espera al final.

Por eso tiene mucho sentido usar código asíncrono ⏸🔀⏯ para las APIs web.

### CVE-2022-3162: Unauthorized read of Custom Resources

A security issue was discovered in Kubernetes where users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different type in the same API group they are not authorized to read.

**Affected Versions**:
  - kube-apiserver v1.25.0 - v1.25.3
  - kube-apiserver v1.24.0 - v1.24.7
