title: How to stop the current Index creation Operation in DynamoDB?
body: <p>I am try to add an index in DynamoDB table having size around 200MB.</p>
  
  <p>its took almost 15 hours and is still running. 
  I have checked that i have given the low read/write IOPS for index.
  Now i want to increase IOPS and restart the index creation activity. </p>
  
  <p>Any idea - If its possible to cancel the current operation ?</p>
  
  <p>Thanks</p>
