> [~saint....@gmail.com] was suggesting to use DataSketches
> (https://datasketches.github.io) in order to write additional statistics to
> the HFiles. This could be used to improve our split decisions,
> troubleshooting or potentially do other interesting analysis without having
> to perform full table scans. The statistics could be stored as part of the
> HFile but we could initially improve the visibility of the data by adding
> some statistics to HFilePrettyPrinter.
