Julian Hyde commented on CALCITE-1589:
--------------------------------------
Looks good, but can you add a test case to DruidAdapterIT that returns the
wrong results if this bug is not fixed? I'm guessing that a very restrictive
WHERE clause would do it.
> Druid adapter: timeseries query shows all days, even if no data

> Key: CALCITE-1589
> URL: https://issues.apache.org/jira/browse/CALCITE-1589
> Project: Calcite
> Issue Type: Bug
> Components: druid
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
> Priority: Critical
> Fix For: 1.12.0
>
>
> Following query is transformed into timeseries Druid query which yields
> different results in Calcite vs Druid, since it will show all values for the
> given time granularity, even if there is no data for the given _i\_brand\_id_.
> {code:sql}
> SELECT floor_day(`__time`) as `granularity`, max(ss_quantity),
> sum(ss_wholesale_cost)
> FROM store_sales_sold_time_subset
> WHERE i_brand_id = 10001009
> GROUP BY floor_day(`__time`)
> ORDER BY `granularity`;
> OK
