**FastAPI** knows what to do in each case and how to reuse the same object, so that all the background tasks are merged together and are run in the background afterwards:


{* ../../docs_src/background_tasks/tutorial002_an_py310.py hl[13,15,22,25] *}

Auf diese Weise können Sie die Dinge für den Client-Code richtig ordnen und gruppieren:

In diesem Fall haben Sie:

* `ItemsService`
* `UsersService`

### Client-Methodennamen

Im Moment sehen die generierten Methodennamen wie `createItemItemsPost` nicht sehr sauber aus:

```TypeScript

	// remove to avoid it from appearing as part of
	// response headers. e.g, X-Minio-* or X-Amz-*.
	// Tags have also been extracted, we remove that as well.
	objInfo.UserDefined = cleanMetadata(fi.Metadata)

	// All the parts per object.
	objInfo.Parts = fi.Parts

	// Update storage class
	if fi.TransitionTier != "" {
		objInfo.StorageClass = fi.TransitionTier
	} else if sc, ok := fi.Metadata[xhttp.AmzStorageClass]; ok {

"s3:ReplicateDelete", "s3:GetBucketObjectLockConfiguration" etc depending on whether delete replication rules are set up or if object locking is disabled on `destbucket`. The above policies assume that replication of objects, tags and delete marker replication are all enabled on object lock enabled buckets. A sample script to setup replication is provided [here](https://github.com/minio/minio/blob/master/docs/bucket/replication/setup_replication.sh)

To set up replication from a source bucket `srcbucket`...
