title: Impala KUDU table - howto bulk update
body: <p>I need to performing updates of KUDU table, Is there any option to du update in bulk?</p>
  
  <p>The flow is following:
  1 .Fetch 1000 rows
  2. Process rows, calculate new value for each row
  3. Update KUDU table with new values</p>
  
  <p>Updating row by row with one DB query per row - slow. I am seeking bulk update solution. I found only this "You can update in bulk using the same approaches outlined in Inserting In Bulk." here <a href="https://www.cloudera.com/documentation/kudu/latest/topics/kudu_impala.html#update_bulk" rel="nofollow noreferrer">https://www.cloudera.com/documentation/kudu/latest/topics/kudu_impala.html#update_bulk</a> but how to du this? I need example, if it is possible
  Thanks</p>
