Vineet Garg commented on HIVE-19674:
------------------------------------
bq. Wonder if its possible to avoid this call altogether
getPulledUpPredicates() is used to figure out if any of the input ref
expressions are constant. I am not sure what else to use to figure it out. I
notice calcite rules like AggregateProjectPullUpConstantsRule use the same call.
bq. can we make that condition even more tighter?
Since we want to replace all {{group by <constant key(s)>}} I am not sure how
can this call be made more tight.
[~jcamachorodriguez] any suggestions?
> Group by Decimal Constants push down to Druid tables.
