iercan opened a new issue, #12621:
URL: https://github.com/apache/druid/issues/12621
We were facing below exception on some queries sent from superset. I did
some investigation and realized it occurs if same key used in filter more than
once. For example
```
SELECT TIME_FLOOR(CAST("__time" AS TIMESTAMP), 'P1D') AS "__timestamp",
"id" AS "id",
sum("count") AS "SUM(count)"
FROM "druid"."example_table"
WHERE "__time" >= '2022-05-31 12:47:38.000000'
AND "__time" <= '2022-06-07 12:47:38.000000'
AND "key" IN ('value1')
AND "key" IN ('value2')
GROUP BY "id",
TIME_FLOOR(CAST("__time" AS TIMESTAMP), 'P1D')
ORDER BY "SUM(count)" DESC
LIMIT 10000
```
Above query throws exception. If I remove one of key filter, it solves
problem. If I add value1 to second filter like `"key" in ('value1, 'value2')`
without removing first one, it also solves problem. I believe this is a bug
```
