If you need to perform heavy background computation and you don't necessarily need it to be run by the same process (for example, you don't need to share memory, variables, etc), you might benefit from using other bigger tools like <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a>.

Wenn Sie umfangreiche Hintergrundberechnungen durchführen müssen und diese nicht unbedingt vom selben Prozess ausgeführt werden müssen (z. B. müssen Sie Speicher, Variablen, usw. nicht gemeinsam nutzen), könnte die Verwendung anderer größerer Tools wie z. B. <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a> von Vorteil sein.

/// info | Примечание

В веб-сокете вызывать `HTTPException` не имеет смысла. Вместо этого нужно использовать `WebSocketException`.

Закрывающий статус код можно использовать из <a href="https://tools.ietf.org/html/rfc6455#section-7.4.1" class="external-link" target="_blank">valid codes defined in the specification</a>.

Later, for your production application, you might want to use a database server like **PostgreSQL**.

/// tip

There is an official project generator with **FastAPI** and **PostgreSQL** including a frontend and more tools: <a href="https://github.com/fastapi/full-stack-fastapi-template" class="external-link" target="_blank">https://github.com/fastapi/full-stack-fastapi-template</a>
