But you see that we are having some code repetition here, writing `CommonQueryParams` twice:

//// tab | Python 3.10+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[14] *}

`.add_task()`는 다음 인자를 받습니다:

* 백그라운드에서 실행될 작업 함수(`write_notification`).
* 작업 함수에 순서대로 전달되어야 하는 인자 시퀀스(`email`).
* 작업 함수에 전달되어야 하는 키워드 인자(`message="some notification"`).

## 의존성 주입 { #dependency-injection }

`BackgroundTasks`는 의존성 주입 시스템에서도 동작하며, *경로 처리 함수*, 의존성(dependable), 하위 의존성 등 여러 수준에서 `BackgroundTasks` 타입의 매개변수를 선언할 수 있습니다.

Grab the async profiler from https://github.com/jvm-profiling-tools/async-profiler
and run `prof async` like so:
```
gradlew -p benchmarks/ run --args 'LongKeyedBucketOrdsBenchmark.multiBucket -prof "async:libPath=/home/nik9000/Downloads/tmp/async-profiler-1.8.3-linux-x64/build/libasyncProfiler.so;dir=/tmp/prof;output=flamegraph"'
```
