What is an ascending (or descending) key segment ?
A key segment can either be sorted in ascending (lowest value to highest value) or descending (highest value to lowest value) order.
Almost all key segments in Venice tables will be in ascending order, but there are a few exceptions.
Note that this affects the meaning of "Greater" when you are doing a "Greater than" or "Greater or Equal to" SeekBy or doing a GetNext(). For a descending key segment this meaning is reversed so a "Greater" will find a smaller value, and a GetNext() will move towards a smaller value.
The analogous is true for the meaning of "Less" and GetPrevious().
