@marcin-krystianc This minor fixes the problem that `distinct_count == 0`, and `None` means we didn't has the `distinct_count`. They share the different syntax. Besides, it's a bit tricky to calc the distinct count: 1. For page-level statistics, calc a distinct count among pages might be hard 2. For column-chunk statistics, only for dictionary column without fallback to plain should have exact "distinct_count" here -- This is an automated message from the Apache Git Service.
