    Description

      Currently, when there is a filter on top of an aggregate e.g. on the result of an aggregation function, we do not push that filter to Druid.

      However, Druid supports 'having' clause for GroupBy queries, thus we should translate the Filter on top of the Aggregate and push it to Druid.
