Hi,

Datamap API currently miss an important input parameter `IndexColumns`. It is common that we only want to implement one type of DataMap but can apply to different data and different column set. In PR 1399, there are no specified index columns. I think it would be nice to include that in the API.

Thanks,
Dong
