title: How to get rid of old messages from Azure EventHub?
body: <p>When we subscribe to an EventHub for a particular type.
  I see my worker keeps processing the old messages as well.
  Is there any way to get rid of older messages in the event hub or change the partition's offset value at a desired message manually?
  As of now our worker doesn't keep track of processed messages when the worker reboots the Checkpoint is not save and the old messages are re-processed...
  So Can anyone share a way to get rid of this issue?</p>
  
  <p>Thanks in Advance,
  Radha.</p>
