Ashutosh Chauhan commented on HIVE-12893:
-----------------------------------------
When all columns are constant folded, we disable SDPO, but do we also convert
this to static partition insert code path? Perhaps here:
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/ConstantPropagateProcFactory.java#L1220
Didn't get the intended behavior for case of subset getting folded. In the
existing test case it seems like ReduceSinkDedup wasn't kicking in. Was that
the primary bug being fixed here?

> 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.
