      Description

      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)
      • Better delineation of allTextMode behavior
