I have drafted a solution using a private enumeration, please let me know if
I got what you meant

> Key: HIVE-26243

> Project: Hive
> Issue Type: Improvement
> Components: UDF, Vectorization
> Affects Versions: 4.0.0-alpha-2

> _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.
