The [proposal](https://github.com/apache/arrow-adbc/pull/765) was updated to include min/max value and max byte width as standardized statistics. Digging into the Hive code, histograms are implemented but top/bottom K never were. The proposal allows for backends to return custom statistics so Hive/Postgres could still encode histograms (the encoding with Arrow gets very messy, however, given the lack of an 'any' type; they would have to pack the histogram values into a binary column). -- This is an automated message from the Apache Git Service.
