>          Issue Type: Improvement
>          Components: C++

> A few changes to ColumnWriter and its derived classes:
> 1. in add() function, re-order code to verify input parameters before 
> modifying any internal state.
> 2. in add() function, move the calls to colIndexStatistics->increase(1) out 
> of the loop. Many of those are virtual function calls.
