# Background Tasks - `BackgroundTasks`

You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```

	maxIO, maxWait, _ := globalHealConfig.Clone()
	waitForLowIO(maxIO, maxWait, currentHTTPIO)
}

func initBackgroundHealing(ctx context.Context, objAPI ObjectLayer) {
	bgSeq := newBgHealSequence()
	// Run the background healer
	for i := 0; i < globalBackgroundHealRoutine.workers; i++ {
		go globalBackgroundHealRoutine.AddWorker(ctx, objAPI, bgSeq)
	}

	globalBackgroundHealState.LaunchNewHealSequence(bgSeq, objAPI)
}

	}
}

func initAutoHeal(ctx context.Context, objAPI ObjectLayer) {
	z, ok := objAPI.(*erasureServerPools)
	if !ok {
		return
	}
