-----------------------------------------

One small nit on RB, and tests need to be fixed.

> If all partition columns are constant folded then sorted dynamic partitioning should
not be used as it is similar to static partitioning. But if only subset of partition columns
are constant folded sorted dynamic partition optimization will be helpful. Currently, this
optimization is disabled if atleast one partition column constant folded.
