Se você tiver esse caso específico usando SQLModel (ou SQLAlchemy), você poderia fechar explicitamente a sessão depois que não precisar mais dela:

{* ../../docs_src/dependencies/tutorial014_an_py310.py ln[24:28] hl[28] *}

Dessa forma a sessão liberaria a conexão com o banco de dados, para que outras requisições pudessem usá-la.

        /*
         * NOTE: "invoker:install" vs "appassembler:assemble": Both mojos use the artifact installer to put an artifact
         * into a repository. In the first case, the result needs to be a proper local repository that one can use for
         * local artifact resolution. In the second case, the result needs to precisely obey the path information of the
         * repository's layout to allow pointing at artifacts within the repository. Unfortunately,

En este caso, puedes usar `typing.Dict` (o solo `dict` en Python 3.9 y posteriores):

Implementation restriction: A compiler may disallow multiple case
expressions evaluating to the same constant.
For instance, the current compilers disallow duplicate integer,
floating point, or string constants in case expressions.

Estos son cualquier request `OPTIONS` con headers `Origin` y `Access-Control-Request-Method`.

En este caso, el middleware interceptará el request entrante y responderá con los headers CORS adecuados, y un response `200` o `400` con fines informativos.

### Requests simples { #simple-requests }

Cualquier request con un header `Origin`. En este caso, el middleware pasará el request a través de lo normal, pero incluirá los headers CORS adecuados en el response.
