SELECT k AS KEY, SUM(p) AS pv
FROM (
SELECT tumble_start(stime, INTERVAL '1' minute) AS k
, COUNT(*) AS p
FROM flink_test1
GROUP BY tumble(stime, INTERVAL '1' minute)
UNION ALL
SELECT tumble_start(stime, INTERVAL '1' minute) AS k
, COUNT(*) AS p
FROM flink_test2
GROUP BY tumble(stime, INTERVAL '1' minute)
) t
GROUP BY k
The Result of executing this sql is about 7000 per minute.But the result is 60
per minute for per table.Is there an error in your SQL statement?
