Kouhei Sutou commented on ARROW-9843:
-------------------------------------
Yes. We should support all boundaries: {{left < X < right}}, {{left <= X
right}}, {{left < X <= right}} and {{left <= X <= right}}
The default should be {{left <= X <= right}} like pandas and SQL's {{BETWEEN}}.
We can use {{FunctionOptions}}
https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/function.h#L60
feature for it. For example, {{min_element_wise}} uses the {{FunctionOptions}}
feature:
