> _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.
