Hi,
I've updated the PoC of arrow::ArrayStatistics:
https://github.com/apache/arrow/pull/42133
Changes:
* Move arrow::ArrayStatistics from arrow::ArrayData to
arrow::Array
* Because arrow::ArrayData is mutable. If we change
arrow::ArrayData, we should update or remove associated
stat

I think that we're considering the following schema:
>> map<
