title: Automatically Drop and Recreate current indexes
body: <p>I'm working on providing a method to allow for bulk updating our tables ( greater than 1M new or updated rows per update) and was interested in dropping the current indexes and recreating them after the updates. </p>
  
  <p>I was wondering if anyone has a script to provide loose coupling of these operations so that if the indexes change over time, the update process does not change.  </p>
  
  <p>It seems like this is one of those things that the community has already probably solved.</p>
