Review Comment:
why not do the same for long stats?
could we refactor `StatObjectConverter.fillColumnStatisticsData` and drop
the repetition: Object llow, Object lhigh, Object dlow, Object dhigh, Object
declow, Object dechigh. Anyways they are populated with exact same values.
Then we can reuse method in StatsUtils.
