Hi folks! I would like to discuss next question: In PR #2965 (https://github.com/apache/flink/pull/2965) I have added support for such operators as CUBE / ROLLUP / GROUPING SETS in SQL queries. Should we do support for the same functionality in Table API? And if so, how will it look? Something like this `table.groupingBy("cube(...)").select("...")`, or `table.cube(...).select(...)` or something else?
Regards, Alexander
