Hi fanbin: It is "distinct aggregates for group window" in batch sql mode. Now, legacy planner: not support. blink planner: not support. There is no clear plan yet. But if the demand is strong, we can consider supporting it.

Hi, Just found that count distinct is supported in streaming but not in batch (version 1.8), is there any plan to add this to batch? SELECT user_id , hop_end(created_at, interval '30' second, interval '30' second) as bucket_ts , count(distinct name) FROM $table GROUP BY user_id , hop(created_at, interval '30' second, interval '30' second) Thanks, Fanbin
