[jira] [Created] (DRILL-1774) Improve JSON Performance

Jacques Nadeau created DRILL-1774:
-------------------------------------

             Summary: Improve JSON Performance
                 Key: DRILL-1774
                 URL: https://issues.apache.org/jira/browse/DRILL-1774
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Jacques Nadeau
            Assignee: Jacques Nadeau


There are multiple reasons that JSON performance is subpar.  We need to update the reader to do the following:

- Avoid double reading (for rewinding)
- Take advantage of Jackson interning/hashing of field names.
- Improve field selection behavior. (avoid object creation and multiple traversals)
- Support filter pushdown
