Maryann Xue commented on PHOENIX-3050:
--------------------------------------

[~jamestaylor], it turns out to be a bug in skip-scan rather than the join 
optimization. So could you please take a look at PHOENIX-4322? As soon as that 
gets fixed, I can enable this optimization on DESC columns right away.

> We found that child/parent join optimization would not work with DESC pk 
> columns. So as a quick fix for PHOENIX-3029, we simply avoid DESC columns 
> when optimizing, which would have no impact on the overall approach and no 
> impact on ASC columns.
>  
> But eventually we need to make the optimization work with DESC columns too.
