LazySimpleSerDe should parse "NULL" dates faster

    XMLWordPrintableJSON

    Details

      Description

      Date string which contain "NULL" or "(null)" are being parsed through a very slow codepath involving exception handling as a normal codepath.

      These are currently ~4x slower than parsing an actual date field.
