Kevin Risden commented on CALCITE-2736:
---------------------------------------

Moving fix version to 1.20.0 since it looks like this change caused some issues 
for Hive and no new test case has been provided. PR is still outstanding as 
well.

> ReduceExpressionsRule never reduces dynamic expressions but this should be 
> configurable

> There are situations where it is helpful to reduce dynamic SqlCalls. Right 
> now, the ReduceExpressionsRule always avoids doing this. We should enhance 
> the rule so this can be configurable depending on where in planning the rule 
> is used.
