------------------------------------------------
Summary: Druid adapter: wrong semantics of groupBy query limit
with granularity
Key: CALCITE-1579
URL: https://issues.apache.org/jira/browse/CALCITE-1579
Project: Calcite
Issue Type: Bug
Components: druid
Affects Versions: 1.11.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Priority: Critical
Similar to CALCITE-1578, but for GroupBy queries. Limit is applied per
granularity unit, not globally for the query.
Currently, the following SQL query infers granularity 'day' for Druid _groupBy_
and pushes the limit, which is incorrect.
{code:sql}
SELECT i_brand_id, floor_day(`__time`), max(ss_quantity),
sum(ss_wholesale_cost) as s
FROM store_sales_sold_time_subset
GROUP BY i_brand_id, floor_day(`__time`)
ORDER BY s
LIMIT 10;
{code}
