Jesus Camacho Rodriguez updated HIVE-11627:
-------------------------------------------
Description: We retrieve the ExprInfo from the map each time we want to
change any of its properties. Instead, the number of calls to the map could be
drastically reduced by retrieving the ExprInfo once, and changing all its
properties.
> Make PPD optimizer run faster
