In my Druid data source, I have a hyperUnique aggregation (ingestion time) on one of the fields.
I am trying to do the equivalent of COUNT(DISTINCT(<hyperunique_field>)) on this aggregated field. Is it supported in the Calcite Druid Adapter? If so, what is the correct way to go about it? P.S. In plywood, I can do COUNT_DISTINCT P.S. running the above returns 0 counts SQL select floor("__time" to HOUR) time_bucket,”field_1", count(distinct(“ingestion_time_aggregated_field")) as uniq from “datasource" where "__time" between '2017-01-01 00:00:00' and '2017-01-02 00:00:00' and “field_1" in (‘value_1') and “field_2”='value_2' and “field_3”='value_3' and “field_4”='value_4' group by floor("__time" to HOUR),”field_1" order by floor("__time" to HOUR); ingestion_time_aggregated_field: {"name": "ingestion_time_aggregated_field", "type": "hyperUnique","fieldName": “field” } Your help is much appreciated, Thanks, Vihag Gupta
