# 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
```

      #   - regex: (server|pod)
      #     action: labeldrop
    namespace: ~
    # Scrape interval, for example `interval: 30s`
    interval: ~
    # Scrape timeout, for example `scrapeTimeout: 10s`
    scrapeTimeout: ~

    public void visitTypes(Action<TypeMetaData> action) {
        if (wildcard) {
            return;
        }
        if (upperBounds != null) {
            upperBounds.visitTypes(action);

        }
        if (lowerBounds != null) {
            lowerBounds.visitTypes(action);
            return;
        }

        action.execute(this);
        if (typeArgs != null) {

The key factor is that a dependency should be a "callable".

A "**callable**" in Python is anything that Python can "call" like a function.

So, if you have an object `something` (that might _not_ be a function) and you can "call" it (execute it) like:

```Python
something()
```

or

```Python
something(some_argument, some_keyword_argument="foo")
```

	}
	// cleaning up the backend by removing all the directories and files created on function return.
	defer removeRoots(disks)

	// uses *testing.B and the object Layer to run the benchmark.
	runPutObjectPartBenchmark(b, objLayer, objSize)
}

// creates Erasure/FS backend setup, obtains the object layer and calls the runPutObjectBenchmark function.
func benchmarkPutObject(b *testing.B, instanceType string, objSize int) {

        builder.append(type.getSignature());
        builder.append(" ");
        builder.append(name);
        return builder.toString();
    }

    @Override
    public void visitTypes(Action<TypeMetaData> action) {
        action.execute(type);
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) {
            return true;
        }
        if (o == null || getClass() != o.getClass()) {

## 3. Update deployment yaml file

Whether you are planning to use Kubernetes StatefulSet or Kubernetes Deployment, the steps remain the same.

If you're using certificates provided by a CA, add the below section in your yaml file under `spec.volumes[]`

```yaml
    volumes:
      - name: secret-volume
        secret:
          secretName: tls-ssl-minio
          items:
          - key: public.crt
