## Canceling a decommission

Stop an on-going decommission in progress, mainly used in situations when the load may be too high and you may want to schedule the decommission at a later point in time.

`mc admin decommission cancel` without an argument, lists out any on-going decommission in progress.

```
λ mc admin decommission cancel alias/

# Подключение WSGI — Flask, Django и другие { #including-wsgi-flask-django-others }

Вы можете монтировать WSGI‑приложения, как вы видели в [Подприложения — Mounts](sub-applications.md){.internal-link target=_blank}, [За прокси‑сервером](behind-a-proxy.md){.internal-link target=_blank}.

Для этого вы можете использовать `WSGIMiddleware` и обернуть им ваше WSGI‑приложение, например Flask, Django и т.д.

## Использование `WSGIMiddleware` { #using-wsgimiddleware }

## Asynchronous Code { #asynchronous-code }

Asynchronous code just means that the language 💬 has a way to tell the computer / program 🤖 that at some point in the code, it 🤖 will have to wait for *something else* to finish somewhere else. Let's say that *something else* is called "slow-file" 📝.

     * <code>groupId:artifactId:version</code> the returned identifier need not be complete. The identifier is derived
     * from the information that is available at the point the problem occurs and as such merely serves as a best effort
     * to provide information to the user to track the problem back to its origin.

Puedes montar aplicaciones WSGI como viste con [Sub Aplicaciones - Mounts](sub-applications.md){.internal-link target=_blank}, [Detrás de un Proxy](behind-a-proxy.md){.internal-link target=_blank}.

Para eso, puedes usar `WSGIMiddleware` y usarlo para envolver tu aplicación WSGI, por ejemplo, Flask, Django, etc.
