- Kube-scheduler now falls back to emitting events using core/v1 Events when events.k8s.io/v1beta1 is disabled. ([#83692](https://github.com/kubernetes/kubernetes/pull/83692), [@yastij](https://github.com/yastij))

Vamos criar as tabelas do banco de dados quando o aplicativo for iniciado.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[32:37] hl[35:37] *}

Aqui, criamos as tabelas em um evento de inicialização do aplicativo.

Para produção, você provavelmente usaria um script de migração que é executado antes de iniciar seu app. 🤓
