The python program below waits on mqtt topic `/minio` and prints event notifications on the console. We use [paho-mqtt](https://pypi.python.org/pypi/paho-mqtt/) library to do this.

```py
#!/usr/bin/env python3
from __future__ import print_function
import paho.mqtt.client as mqtt

# This is the Subscriber

def on_connect(client, userdata, flags, rc):
  print("Connected with result code "+str(rc))
  # qos level is set to 1

	registerBucketLevelFunc(bucketRouter, api, apiFunctions...)
}

// Takes in Erasure object layer, and the list of API end points to be tested/required, registers the API end points and returns the HTTP handler.
// Need isolated registration of API end points while writing unit tests for end points.
// All the API end points are registered only for the default case.
