Svend Vanderveken commented on FLINK-17446:
-------------------------------------------
We'd be grateful if that feature was added to Flink.
For info, as a temporary workaround I'm currently writing queries similar to
the one below, which is not ideal since the state would then grow continuously
with each new {{time_period_start}}.
I'd be happy to contribute some testing if/when work start on this feature.
{code:sql}
WITH windowed AS (
SELECT
FLOOR(creation_time TO MINUTE) as time_period_start,
field_1,
field_2
FROM flat_post_events_view),
SELECT
time_period_start,
field_1,
field_1,
count(1) as total_count
FROM windowed
GROUP BY
GROUPING SETS (
(time_period_start, field_1),
(time_period_start, field_2),
(time_period_start, field_1, field_2)
)

> Blink supports cube and window together in group by

> Project: Flink
> Issue Type: New Feature
> Components: API / Core
> Reporter: Liu
> Priority: Minor
>
> Blink planner supports CUBE. CUBE can be used together with a field but
> not window. For example, the following SQL is not supported:
>
> SELECT A, B, sum(C)
> FROM person
> GROUP BY cube(A, B), TUMBLE(curTimestamp, interval '1' minute)
>
> It is a missing feature. Maybe it should be supported. Detail is in
