Description

Enhancement

Our minmax index now is only support for the handle column, and the columns whose data type satisfies isInteger() or isDateorDateTime()).

For lots of other data types, such as float, double, decimal, string, etc, minmax index is unsupported currently.

In order to enhance our index ability, we first can enhance our minmax index for more data types, to utilize our minmax index better.
