how does get_range_slices work?
Hi,
I have a question about the get_range_slices() function about the key sorting.
I inserted some colums with keys of '1', '2' ,'7' and '10'.
When I use get_range_slices to get colums betwen '1' and '10' , I got none.
But When I get colums betwen '10' and '1', I got '10', '2' and '1'.
Can anybody tell me why?
Thanks!

No,It's not the columns, but the rows.
These are the keys of the rows.

What column comparator/type are you using? Remember that if you are using BytesType/UTF8Type, columns will be sorted lexicographically.
