   You might have to set the `groupby.trim.threshold` property as well. It's set to 1M by default so anything above that gets trimmed at the group by operator.
   
   See this code for more info: https://github.com/apache/pinot/blob/ae443e28f10acc349f3a3c4bec9a510fa6a4541a/pinot-core/src/main/java/org/apache/pinot/core/plan/maker/InstancePlanMakerImplV2.java#L83
