[jira] [Created] (STORM-1505) Add map and flatMap operations in trident api

Arun Mahadevan created STORM-1505:

             Summary: Add map and flatMap operations in trident api
                 Key: STORM-1505
                 URL: https://issues.apache.org/jira/browse/STORM-1505
             Project: Apache Storm
          Issue Type: Improvement
            Reporter: Arun Mahadevan
            Assignee: Arun Mahadevan


map and flatMap are common stream operations. 

Right now in trident this has to be implemented via each() which also sends the input field values in addition to the mapped field values, so the map and flatmap should make things slightly more efficient and easy.
