Remove dataset sorting from WFS.

    XMLWordPrintable

Details

    Description

      WFS is a separate step that also sorts result set replacing ORDER BY facility completely. After MCOL-3758 is done this doesn't make sense b/c sorting in WFS:

      • single-threaded
      • overlaps with sorting in TNS thus adds extra complexity introducing changes to sorting

      There are two parts that must removed from these WFS methods to disable sorting in WFS:

      • WindowFunctionStep::initialize()
      • WindowFunctionStep::doPostProcessForSelect() runs a variant of merge sort routine
