Add vectorized implementation of the 'ds_kll_sketch' UDAF

    XMLWordPrintableJSON

Details

    Description

      ds_kll_sketch UDAF does not have a vectorized implementation at the moment, the present ticket aims at bridging this gap.

      This is particularly important because vectorization has an "all or nothing" approach, so if this function is used at the side of vectorized functions, they won't be able to benefit from vectorized execution.
