Lunny Xiao 4a7ab0abf0 Optimize heatmap query (#33853) ... When there are over 5M records on `action` table, the heatmap on dashboard is very slow as below SQL. ``` database duration=1.8881s db.sql="SELECT created_unix DIV 900 * 900 AS timestamp, count(user_id) as contributions FROM `action` WHERE user_id=? AND act_user_id=? AND (created_unix > ?) GROUP BY timestamp ORDER BY timestamp" ``` This PR add a new index for `action` table with columns `user_id`, `act_user_id` and `created_unix` so that this query will become about 6 times faster than before.		2025-03-20 09:30:45 -07:00
