如果您需要执行繁重的后台计算，并且不一定需要由同一进程运行（例如，您不需要共享内存、变量等），那么使用其他更大的工具（如 <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a>）可能更好。

它们往往需要更复杂的配置，即消息/作业队列管理器，如RabbitMQ或Redis，但它们允许您在多个进程中运行后台任务，甚至是在多个服务器中。

要查看示例，查阅 [Project Generators](../project-generation.md){.internal-link target=_blank}，它们都包括已经配置的Celery。

但是，如果您需要从同一个**FastAPI**应用程序访问变量和对象，或者您需要执行小型后台任务（如发送电子邮件通知），您只需使用 `BackgroundTasks` 即可。

## 回顾

In an advanced scenario where you know you need the dependency to be called at every step (possibly multiple times) in the same request instead of using the "cached" value, you can set the parameter `use_cache=False` when using `Depends`:

=== "Python 3.8+"

    ```Python hl_lines="1"

    request: Request,
    proxyType: Proxy.Type,
  ): Boolean {
    return !request.isHttps && proxyType == Proxy.Type.HTTP
  }

  /**
   * Returns the path to request, like the '/' in 'GET / HTTP/1.1'. Never empty, even if the request
   * URL is. Includes the query component if it exists.
   */
  fun requestPath(url: HttpUrl): String {
    val path = url.encodedPath
    val query = url.encodedQuery

## Composition by architecture modules

Each [architecture module and platform](platforms.md) can contribute code to any of the runtimes.
Not every module contributes to every runtime.

The core-runtime module defines each runtime:

- The target JVM for the runtime. Each runtime has its own JVM compatibility constraints.
