# 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
```

			// skip all objects that are created before the specified time.
			return false
		}

		if !r.Flags.Filter.CreatedBefore.IsZero() && r.Flags.Filter.CreatedBefore.After(info.ModTime) {
			// skip all objects that are created after the specified time.
			return false
		}

		if len(r.Flags.Filter.Tags) > 0 {
			// Only parse object tags if tags filter is specified.
			tagMap := map[string]string{}
