[GitHub] [druid] maytasm opened a new issue #9974: Improve groupBy on timestamp_floor expressions so that it matches timeseries query's performance

maytasm opened a new issue #9974:
URL: https://github.com/apache/druid/issues/9974


   ### Description
   
   Improve groupBy on timestamp_floor expressions so that it matches timeseries query's performance.
   
   ### Motivation
   
   When groupBy on timestamp_floor expressions is just as fast as a timeseries query (a noble goal) we can remove timeseries queries from the SQL. With this, we can remove multiple hacks that we put in our query engine to handle the special case of timeseries query with groupBy on timestamp_floor expressions.
