             Summary: Optimize populating user group mappings from DB.
                 Key: RANGER-2753
                 URL: https://issues.apache.org/jira/browse/RANGER-2753
             Project: Ranger
          Issue Type: New Feature
          Components: Ranger
            Reporter: Sailaja Polavarapu
            Assignee: Sailaja Polavarapu


As part of ranger userstore cache, user to group mappings are built from DB. Current implementation
opens lot of DB connections which is very performance intensive operation.
