count distinct not supported in batch?

[Fanbin Bu]

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
